Heart of Gold clip to windward
So why don't you find us the polars from any 35 foot boat that claims a VMG to windward of 6 knots in any wind condition? I've read time and again about vessels beating their polars, Jeff and I bet you have as well. Polars are like hull speed....they're there to be surpassed! While you're at it, find us one that does it without going higher than 45 degrees. You still are commenting without knowing my POS, which is really the probem here! Oh, and catamarans don't count! My PDQ actually does have a VMG of 6.2 at 47 degrees in 20 knots true wind. I guess that means I would toast you upwind! Your cat is not a monohull and is about twice the size overall of my boat! I'd need two slips for it here! The comparison is about as relevant as comparing your boat to a F boat. At 14 knots, perhaps 38 degrees. Not that high at all, and winds were actually closer to 17 knots at times where we were. Wrong answer. VMG to a mark is quite different from VMG to Windward. The mark WAS to WINDWARD. So now you're claiming that you connected your instruments to your friend's handheld? Why would you do that? Never claimed that, but he's an experienced navigator and had all the info in front of him. I don't know all of the features of the latest handheld Garmins, but I don't believe they will pick up the wind data from your instruments. Perhaps you can enlighten us as to how this works. Are you now claiming that if you have a compass, wind instruments, GPS, mechanical knotmeter, you can't make a good estimate on VMG? But you said, many times, that you were talking about "VMG to Windward," not the VMG to a mark. Nope. But that's pretty creative! I have maintained that the MARK was to WINDWARD and WINDWARD is any course above a beam reach. That's the problem you have I knew it!!!! , you kept insisting that you weren't "hard on the wind" or beating, and that I couldn't predict your speed without knowing the exact point of sail. I wasn't beating, the video shows that clearly. But I don't have to, because by your own admission, the best you could have been doing is maybe 5.2 knots and it goes downhill from there. I admitted I was doing a VMG of 5.2 knots with my speed over ground at 8 knots or higher? So what do you mean when you insist that your boat can outperform its polars by 15%? It depends on the polars, who made them and how the aspects of a given design have been learned since. A 35s5 can do better than the polars made when she was built You do know who Steve Killing is, I assume. Didn't he make one of the ugliest boats ever in the Express 30? Most Nonsuch owners that I knew routinely tweaked their outhauls (called "chokers" by Ellis) as the wind changed, or they changed point of sail. The Nonsuch is not a twin spreader fractional sloop designed for cruising and around the bouys racing. Underway??? I'm impressed! Outside of using a guage and best guess tuning, how else would I do it except underway? Still probably too close, in one minute the angle would change around 6 degrees, so it really isn't directly upwind. Well, you didn't say this before. You said 1/4 mile would be too close. Your insistence that you were not beating simply created a hole for you that you can't crawl out of. I think I've done rather well. Busted! Yep, but don't beat yourself up over it. Now ask yourself, at what POS can a quick monohull make 6 knots VMG in 17 knots of wind? RB 35s5 NY |

I've read time and again about vessels beating their polars, Jeff and I bet you have as well. Polars are like hull speed....they're there to be surpassed! Yes, they can be surpassed by small amounts, and hi-tech sails can raise the bar a notch. However, the 15% improvement you're claiming would imply a 100 point PHRF improvement. Are you claiming that boats are routinely outperforming their PHRF by 100 points? When I asked if that meant a Westsail could go as fast as your benny or if your benny could go as fast as a Frers 45, and you said no. So it would appear that your major burst of speed only works on boats that are not racing, when no one is watching. What a pity. As always, you've demonstrated a complete lack of understanding of the way boats work. While you're at it, find us one that does it without going higher than 45 degrees. You still are commenting without knowing my POS, which is really the probem here! You kept saying you weren't pointing that high. However, you actually admitted several times that you have no idea what your point of sail actually was. So tell us Bob, were you even there? Its looking like you loaned your boat to someone else and asked them to take some videos. Then you tried to make up a lame story about it. Oh, and catamarans don't count! My PDQ actually does have a VMG of 6.2 at 47 degrees in 20 knots true wind. I guess that means I would toast you upwind! Your cat is not a monohull and is about twice the size overall of my boat! I'd need two slips for it here! The comparison is about as relevant as comparing your boat to a F boat. I mentioned it only because you and others are always so quick to point out the poor upwind performance of my cat. However, with a wind over 12-14 knots, my VMG to Windward exceeds that of even performance monohulls with the same length and sail area. Actually, my leeway will be higher so that advantage might be lost, but cats with boards (including the "express" version of mine) don't have that problem, and easily walk away from monohulls upwind in a breeze. Wrong answer. VMG to a mark is quite different from VMG to Windward. The mark WAS to WINDWARD. Sometime you say that, other times you don't. You don't know what the words mean or what your boat was doing. You probably weren't even there. So now you're claiming that you connected your instruments to your friend's handheld? Why would you do that? Never claimed that, but he's an experienced navigator and had all the info in front of him. You said several times he was reading off his GPS. A GPS alone simply can't report an accurate VMG to Windward, especially set to a nearby mark. Frankly I'm skeptical as to whether a basic system like Ray ST60 can do it, I certainly take my instruments with a huge grain of salt. Actually, that's one of the basic issues of the discussion; you should have realized immediately that a VMG to Windward of 6 knots was bogus. Its even possible that you could have momentarily hit that when close to the wind (but even then it would be bogus), but doing it when footing off (as you claim, sometimes) is a physical impossibility. Every sailor knows that, so its not surprising that you don't. Are you now claiming that if you have a compass, wind instruments, GPS, mechanical knotmeter, you can't make a good estimate on VMG? Sure, within about 15%. That's a pretty good estimate. (Actually, I'm not sure you could even do that good unless you had a quality setup and ideal conditions.) This is actually one of the most difficult things to measure. Think about what happens if you get a 5 degree header: Your instantaneous VMG to windward jumps half a knot, but if you don't react the boat starts to slow down. In a shifty wind, its quite easy to have a high VMG to the *average* wind, simply by playing the wind shifts. This, however, is not the same thing as VMG to Windward. But you said, many times, that you were talking about "VMG to Windward," not the VMG to a mark. Nope. But that's pretty creative! I have maintained that the MARK was to WINDWARD and WINDWARD is any course above a beam reach. You also claimed it was "directly to windward." So are you now claiming that "directly to windward" means anything on the windward side of your boat? Of course, you don't understand the meaning of these words, do you? I wasn't beating, the video shows that clearly. which video? Frankly, all of them are so poor that very little can be deduced about the performance. Why can't you actually tell use how close to the wind you were sailing? Weren't you there? But I don't have to, because by your own admission, the best you could have been doing is maybe 5.2 knots and it goes downhill from there. I admitted I was doing a VMG of 5.2 knots with my speed over ground at 8 knots or higher? Yes, you did. Again, you're showing your ignorance. I outlined the VMG to Windward that was implied by your claim of 8 knots. Since you were unable to tell point of sail (Gawd, are you that stupid???) I did the simple eighth grade math, to generate the VMG to Windward. Its apparent that you don't understand that VMG to Windward is actually defined mathematically from your course with respect to the true wind and your speed through the water. You gave the speed, I computed the VMG to Windward for different courses. Here it is again. Remember, this is what you told us, not some abstraction that could be debated. The 8 knots speed through the water, at 45 degrees to the wind, yields a VMG of 5.65 knots. At 50 degrees this becomes 5.1, at 55 degrees its 4.6, and at 60 its 4 knots. This doesn't include leeway, which the GPS would pick up, so you have to add 3 to 4 degrees and degrade the performance accordingly. So this is what you told us. You insisted that you were not "hard on the wind" and that your sails were not sheeted in. The closest you could have been pointing, and still moving efficiently, is 50 degrees. Thus, by your own admission, you best VMG to Windward was actually about 5 knots, probably even less with leeway. Then you seemed to be saying maybe it was 55 degrees, so the VMG to Windward was really well under 5 knots. So what do you mean when you insist that your boat can outperform its polars by 15%? It depends on the polars, who made them and how the aspects of a given design have been learned since. A 35s5 can do better than the polars made when she was built Maybe a bit, but not 15% upwind. You do know who Steve Killing is, I assume. Didn't he make one of the ugliest boats ever in the Express 30? The Express is a beauty compared to your boat. I usually don't talk much about the aesthetics of modern boats, but since you brought it up, I always thought yours was uglier than a mud fence. Most Nonsuch owners that I knew routinely tweaked their outhauls (called "chokers" by Ellis) as the wind changed, or they changed point of sail. The Nonsuch is not a twin spreader fractional sloop designed for cruising and around the bouys racing. yada yada yada. Whenever you lose an argument, you start using terms that you don't understand so you sound important. What a putz! Still probably too close, in one minute the angle would change around 6 degrees, so it really isn't directly upwind. Well, you didn't say this before. You said 1/4 mile would be too close. Yes I did. What about it? It doesn't change the math. And you should have known it. I did say that to be valid, the mark would have to be far away, directly upwind. Clearly, at 3/4 of a mile, a mark doesn't stay directly upwind for very long. Its also true the the wind would have to be steady, especially in direction, but also in strength. Moreover, you've said the mark was directly upwind, that it was 3/4 of a mile away, that you were closing on it, and that you weren't beating. Please explain how all of this could be true. Its looking more and more like your weren't even out there that day. Your insistence that you were not beating simply created a hole for you that you can't crawl out of. I think I've done rather well. If your goal was to demonstrate total ignorance about sailing, you've succeeded admirably! Busted! Yep, but don't beat yourself up over it. Now ask yourself, at what POS can a quick monohull make 6 knots VMG in 17 knots of wind? Directly To Windward? None, for your boat. But you seem to be confused about the term "VMG to Windward." Ask your friend about it and tell him to draw a picture and use small words. Maybe it will sink in. |

Heart of Gold clip to windward
However, the 15% improvement you're claiming
would imply a 100 point PHRF improvement. Only if the polars were correct. Quite a few boats have prove abilities well beyond the polars originally drawn up. So it would appear that your major burst of speed only works on boats that are not racing, when no one is watching. Nope, it appears on a coarse which you refuse to acknowledge. You kept saying you weren't pointing that high. However, you actually admitted several times that you have no idea what your point of sail actually was. That is to say I don't know the specific number you'd demand for this discussion. So tell us Bob, were you even there? Now you're just being silly. I shot the clips with my Casio. Oh, and catamarans don't count! My PDQ actually does have a VMG of 6.2 at 47 degrees in 20 knots true wind. I guess that means I would toast you upwind! I mentioned it only because you and others are always so quick to point out the poor upwind performance of my cat. Actually, your cat is quite fast, roomy and very practical as a floating home. It's just missing the fun and romance of sailing as many of us prefer. However, with a wind over 12-14 knots, my VMG to Windward exceeds that of even performance monohulls with the same length and sail area. Uh, okay. Jetskis are also faster. Sometime you say that, other times you don't. I have always maintained that the mark was to windward in clip #2, but that we weren't beating. You probably weren't even there. Oh no! You said several times he was reading off his GPS. A GPS alone Who said GPS alone? Were the other instruments to be ignored? Frankly I'm skeptical as to whether a basic system like Ray ST60 can do it, I certainly take my instruments with a huge grain of salt. Well, they're your instruments. Trust them or don't. Actually, that's one of the basic issues of the discussion; you should have realized immediately that a VMG to Windward of 6 knots was bogus. Except that you still refuse to admit that VMG to windward is ANY course above a beam reach. That's a fact. Its even possible that you could have momentarily hit that when close to the wind We weren't very close to the wind. Sure, within about 15%. That's a pretty good estimate. Estimate means GUESS, educated or not. You also claimed it was "directly to windward." So are you now claiming that "directly to windward" means anything on the windward side of your boat? Of course, you don't understand the meaning of these words, do you? Uh, Jeff. Let's try to be honest for a second. Here's my exact quote: "Second clip, still some nice air and off to windward at just over 6 knots VMG.... " OFF TO WINDWARD is not directly to windward, now is it??? Hmmmm? Where is the word DIRECTLY??? Looks like you read my post and inferred what you needed to draw out this entertaining debate! But the fact is that you got it wrong....which is what you wanted to do anyway. which video? Frankly, all of them are so poor that very little can be deduced about the performance. Really? The folks on the Beneteau lists liked them. Can I see one of your video clips that you generously posted to this or some other group? Why can't you actually tell use how close to the wind you were sailing? Weren't you there? Sure I was there. Will you take an estimate? The 8 knots speed through the water, at 45 degrees to the wind, yields a VMG of 5.65 knots. At 50 degrees this becomes 5.1, at 55 degrees its 4.6, and at 60 its 4 knots. This doesn't include leeway, which the GPS would pick up, so you have to add 3 to 4 degrees and degrade the performance accordingly. Sure, read all that...and as I also indicated we TOPPED 8 knots and winds were higher than 14 knots on the water. The 35s5 does a fine job of cutting leeway with her wing. With that in mind my 6 knot claim doesn't appear to be the gross error you make it out to be. And in all of this, knowing we were on the LIS you utterly failed to take into account a favorable current. I did not check, but that also could play a part. You've hardly been complete in your examination of the videos, the facts as presented and so on. Maybe a bit, but not 15% upwind. Are you sure? The Express is a beauty compared to your boat. Not many...and no one I know thinks the Express is a good looking boat. Then again, if you got past the looks of a PDQ 36, anything is possible. I've had nothing but compliments. yada yada yada. Whenever you lose an argument, you start using terms that you don't understand so you sound important. Oh no! Jeff says I lost the argument, so it must be true! What a putz! A putz who sails more than you and has a ton of fun! Doing a short cruise this weekend starting tomorrow afternoon, then delivering a Catalina 34 from Mystic to my club. How much sailing are you getting in? And I'm not even retired! Yes I did. What about it? So you lied. Exactly. It doesn't change the math. And yet you change the numbers when they fail to support you! Moreover, you've said the mark was directly upwind Another lie. I said it was to windward, which is NOT directly to windward regarding course. If your goal was to demonstrate total ignorance about sailing, you've succeeded admirably! Yes, I've exposed you. But I do feel sad about it. Directly To Windward? None, for your boat. But you seem to be confused about the term "VMG to Windward." There he goes again with the "directly" stuff. It's his ace in the a-hole! RB 35s5 NY |

RB Admits Defeat!
The Grand Backpedal Continues. Booby is now denying everything he
said. I guess he talked to his friend who set him straight. Let's see if we can count the number of times he contradicts what he said before, or otherwise demonstrates that he really doesn't understand the basic terminology. (Don't bother counting; the answer is every time he speaks.) Capt. Rob wrote: However, the 15% improvement you're claiming would imply a 100 point PHRF improvement. Only if the polars were correct.

So tell us Bob, were you even there? Now you're just being silly. I shot the clips with my Casio. That does not appear to be true. You can't tell us the point of sail. Sometime you say that, other times you don't. I have always maintained that the mark was to windward in clip #2, but that we weren't beating. Actually you said it was directly to windward. Except for the time when you said it was 10 degrees off the centerline. Of course, after the fact, you changed you mind and said that wasn't so. You said several times he was reading off his GPS. A GPS alone Who said GPS alone? Were the other instruments to be ignored? No, but they don't help that much. You asked if a handheld GPS was inferior, and I said yes it is because it is not integrated with the other instruments. You're just babbling here to cover up your little blunder. Frankly I'm skeptical as to whether a basic system like Ray ST60 can do it, I certainly take my instruments with a huge grain of salt. Well, they're your instruments. Trust them or don't. I trust them, within their limitations. But then, I use them when making actual trips, sometimes offshore. When you never leave sight of your slip you don't have to learn how your instruments work. You can just make up numbers to impress your "friends." Actually, that's one of the basic issues of the discussion; you should have realized immediately that a VMG to Windward of 6 knots was bogus. Except that you still refuse to admit that VMG to windward is ANY course above a beam reach. That's a fact. WRONG! Ask any sailor with experience. "VMG to Windward" has a very specific meaning. It is "the velocity made good in the direction the wind is coming from." It is not the VMG to some other arbitrary point that might happen to be somewhat to windward. If that's what you mean, then you have to VMG to some point. In fact, that is what the GPS reports, it is not "VMG to Windward." Its even possible that you could have momentarily hit that when close to the wind We weren't very close to the wind. You keep saying that. And that's why it is impossible that your VMG to Windward was 6 knots. When you figure out what "VMG to Windward" really means, you might understand this. Sure, within about 15%. That's a pretty good estimate. Estimate means GUESS, educated or not. Do you have a point? You also claimed it was "directly to windward." So are you now claiming that "directly to windward" means anything on the windward side of your boat? Of course, you don't understand the meaning of these words, do you? Uh, Jeff. Let's try to be honest for a second. Here's my exact quote: "Second clip, still some nice air and off to windward at just over 6 knots VMG.... " OFF TO WINDWARD is not directly to windward, now is it??? Hmmmm? Where is the word DIRECTLY??? The concept of directly is implied by "to windward at just over 6 knots VMG." If you hadn't said VMG, it would have been understood as speed through the water by most sailors. But by using "VMG" and "to windward" together, you imply the VMG directly into the wind. Looks like you read my post and inferred what you needed to draw out this entertaining debate! But the fact is that you got it wrong....which is what you wanted to do anyway. I inferred exactly what every sailor would infer. In fact, I explained exactly what the meaning of the phrase was and essentially admitted that you didn't understand the fundamental concept. Why can't you actually tell use how close to the wind you were sailing? Weren't you there? Sure I was there. Will you take an estimate? Given your ability, it would have to be a very coarse estimate. The 8 knots speed through the water, at 45 degrees to the wind, yields a VMG of 5.65 knots. At 50 degrees this becomes 5.1, at 55 degrees its 4.6, and at 60 its 4 knots. This doesn't include leeway, which the GPS would pick up, so you have to add 3 to 4 degrees and degrade the performance accordingly. Sure, read all that...and as I also indicated we TOPPED 8 knots and winds were higher than 14 knots on the water. The 35s5 does a fine job of cutting leeway with her wing. Ooops! You've just opened up another area where you can demonstrate ignorance. Here's a hint: your wing keel does not improve your performance to windward. It allows you to have performance almost as good as the normal keel with a smaller draft. Not too many boats have better upwind performance with a wing keel than with a deep keel. With that in mind my 6 knot claim doesn't appear to be the gross error you make it out to be. Nonsense. Its a pretty gross error. There's almost no 35 footers that can do 6 knots "VMG to Windward" while on a close reach. And since you're not claiming extreme speeds, its a physical impossibility. And in all of this, knowing we were on the LIS you utterly failed to take into account a favorable current. Actually, I mentioned "through the water" several times. And it takes a real jackass to try to explain off a blunder like this by saying you might have been confused by the current! I did not check, but that also could play a part. You've hardly been complete in your examination of the videos, the facts as presented and so on. Why should I? I was very specific about the meaning of "VMG to Windward." I even included "speed through the water." The videos were irrelevant. They only serve to show your ignorance, such as labeling a shot when you're on a close reach as "windward work." What a putz! A putz who sails more than you and has a ton of fun! Doing a short cruise this weekend starting tomorrow afternoon, then delivering a Catalina 34 from Mystic to my club. How much sailing are you getting in? And I'm not even retired! You have to sail another 50,000 miles or so to catch up to me. And if we just count to on the boat away from the dock, you don't even come close to me nowadays. For instance, I've averaged 70 full 24 hour days a year on aboard for the last 14 years. You probably don't do 70 day sail Yes I did. What about it? So you lied. Exactly. I lied? How you you figure that? I said 1/4 mile would be obviously too close, because I could do the math in my head. You said it was more like 3/4 of a mile - that took me a few seconds to do the calculation and it turns out that's also too close. You were there - you should have been able to eyeball it and say its too close because the bearing was shifting. You shouldn't need me to do this for you. And this is central to the discussion. Because you have never learned the fundamentals of sailing, you don't appreciate how stupid you sound when you make your claims. Your VMG of 6 knots was clearly bogus from the beginning, simply because this is extremely high, especially for a 35 foot boat. Once you said you weren't close to the wind, it became a physical impossibility. Everyone except knew that, except for you. And you should have realized immediately that any VMG described in your conditions clearly could not be the correct VMG to Windward. You desperately want everyone to think that you're knowledgeable about sailing, you certainly blown any chance of that with this thread! It doesn't change the math. And yet you change the numbers when they fail to support you! What numbers fail to support me? Moreover, you've said the mark was directly upwind Another lie. I said it was to windward, which is NOT directly to windward regarding course. Oh really??? When I said "Perhaps I should be more explicit: The mark has to be directly to windward. Not slightly to windward of your centerline. There is a huge difference." you replied: "Agreed. I'm giving you the bouy location to best of my ability." And when I said: "So what was it, directly upwind or 10 degrees off the bow?" you said: "In clip #2 it's directly to windward. Do you know what that means?" That certainly sounds like you were saying "directly to windward" to me. So now you're going to claim that "directly to windward" does not mean in the directly from which the wind is blowing, aren't you? You think you can weasel out of this by inventing new definitions of the terms. But no one is buying that. Its painfully clear that you simply didn't know the meaning of the terms until Bob educated you last night. Directly To Windward? None, for your boat. But you seem to be confused about the term "VMG to Windward." There he goes again with the "directly" stuff. It's his ace in the a-hole! No. It what sailors care about. You've just admitted that you really did not understand the meaning of the terms. I hope you thanked Bob for cluing you in on what sailors really talk about. |

RB Admits he has two feet!!
So let's see one that was done in the last 15 or 20 years that was off
by 15% in upwind prediction. What you're claiming is that Beneteau shipped a boat that the polars predicted was as slow upwind as a Westsail. 35s5 owners claim to beat the polars by 7-10%. What course is that? You're the one who doesn't know what course he was on. I've only said it doesn't matter. You keeping begging for the exact course, but it doesn't matter? Oh. I'm not demanding anything. I've only suggested that any sailor who was on the boat at the time might know what point of sail the boat was on. Roughly between 50-60 degrees. How's that? That does not appear to be true. You can't tell us the point of sail. Probably because I was enjoying myself and shooting some nice vids for the group. Someone else was sailing. But I gave you a ROUGH estimate. Actually you said it was directly to windward. Nope, never said that...and if I construed it as such it's wrong. The mark was to windward, but not directly. Except for the time when you said it was 10 degrees off the centerline. For clip #3, yes. Not what we're talking about. No, but they don't help that much. Oh my! I trust them, within their limitations. But then even you must essentially guess at those. By and large modern instruments are pretty good and mine are newer than yours. When you never leave sight of your slip you don't have to learn how your instruments work. You can't see my slip from Execution rocks. You can just make up numbers to impress your "friends." And show a video that impressed them even more....though it upset you for reasons we all understand! WRONG! Ask any sailor with experience. "VMG to Windward" has a very specific meaning. But I clearly made it clear so it would be clear that I was refering to a mark windward of us. How many times can I say it? You don't want to listen to that because then you have nothing left to stew about. You keep saying that. And that's why it is impossible that your VMG to Windward was 6 knots. See above, genius. You really are arguing a point based on something I never said. I know what VMG to windward means, but I was talking about a mark windward of us. The only backpedal here is YOU refusing to acknowledge this little point. Our VMG to the mark, was 6 knots. We were on a windward tack to get there. Can't you figure this out? Three people e-mailed me and THEY understand! Sheesh! Do you have a point? It's at the top of your head. Read above. But I think you're sort of like a mad bull at this point, working hard to keep this debate within the confines of a definition rather than an easy to see reality...both in my statements and in the clip. The concept of directly is implied by "to windward at just over 6 knots VMG." If you hadn't said VMG, it would have been understood as speed through the water by most sailors. But by using "VMG" and "to windward" together, you imply the VMG directly into the wind. Except that I then made it clear that I was sailing for a mark. AGAIN! Oh boy! I inferred exactly what every sailor would infer. Do you think any sailor would continue to make such an inference based on the facts as I gave them? Would they basically choose to ignore the fundamental details? Would they just get it as mind bleedingly wrong as you have??? I hope not!!! and essentially admitted that you didn't understand the fundamental concept. More lies from Jeff the Drunk. Please provide the link to my comment! Ooops! You've just opened up another area where you can demonstrate ignorance. Here's a hint: your wing keel does not improve your performance to windward. It allows you to have performance almost as good as the normal keel with a smaller draft. Not too many boats have better upwind performance with a wing keel than with a deep keel. BZZZZT!!! A perfect example of why you're losing this debate! I never said it outperformed the deep keel version. The Deep keel sails 3-4 points higher and has less leeway. Once again you infered idiocy conjured from your own depths. I simply said the wing does a good job, which it does. A wingless 4.9 draft of the same boat would not perform as well. And by the way, owners that have sailed BOTH versions have claimed less leeway with the wing on a reach all the way to a close reach. Heresay, but there it is. Nonsense. Its a pretty gross error. There's almost no 35 footers that can do 6 knots "VMG to Windward" while on a close reach. Luckily I never made such a claim. You DID! And since you're not claiming extreme speeds, its a physical impossibility. Just like beating hull speed. Guess why there's so little support for you on this, Jeff. Because most folks with experience know polars are often topped by significant margins. Actually, I mentioned "through the water" several times. And it takes a real jackass to try to explain off a blunder like this by saying you might have been confused by the current! Oooooo! Just pointing out that you're incapable of grasping both the gross and finer aspects of this discussion! Why should I? Why should you? Why make all this effort then? I was very specific about the meaning of "VMG to Windward." And I was VERY specific about my comment and what I meant. Why choose to ignore it? So you can argue about an intangible event? And let's not forget that you now claim I wasn't even aboard! You sure are working hard for someone who doesn't care! Wanna get on the phone and talk about it? They only serve to show your ignorance, such as labeling a shot when you're on a close reach as "windward work." Yep, I guess that was downwind work! You have to sail another 50,000 miles or so to catch up to me. I'm 43, Jeff. Lots of time and boats and sails ahead. And if we just count to on the boat away from the dock, you don't even come close to me nowadays. For instance, I've averaged 70 full 24 hour days a year on aboard for the last 14 years. You probably don't do 70 day sail Again with the lame "I sailed further, slept aboard and cooked brownies in the boom" crap. Play with your toys as you please. I lied? How you you figure that? Your VMG of 6 knots was clearly bogus from the beginning, simply because this is extremely high, especially for a 35 foot boat. And you're still wrong, Jeff. Because you've built your position on ignoring the facts. Everyone except knew that, except for you. Huh? Dude, calm down. Take a pill!! And you should have realized immediately that any VMG described in your conditions clearly could not be the correct VMG to Windward. Which is why I explained we were heading for a mark which was upwind and our VMG to that mark was 6 knots. NOTHING you're saying contradicts this. You're hanging onto the "VMG to windward" term for dear life, but you KNOW that's not what I was talking about. You've known it for 20 posts and yet you still prattle on. I think I have a great understanding of VMG. In fact, anyone with some clear understanding would have known what I meant. But even after I explained it...as if you're a two year old...you STILL can't grasp the events! What numbers fail to support me? All of them since you've created an event for my boat that I never described. "In clip #2 it's directly to windward. Do you know what that means?" THAT STATEMENT is in error. I meant that the mark was to windward. That certainly sounds like you were saying "directly to windward" to me. So now you're going to claim that "directly to windward" does not mean in the directly from which ... Nope....and again I think you clearly understand what I meant and I was clear that I was sailing on a windward course for a mark at 6 knots VMG. You don't want to admit to that because it destroys all of your hard work here! But it's much appreciated, Jeff. Last night I looked up a lot of polars online and refined my understanding of them. Now seriously, dude. Calm the F down! I'm sorry you lost this debate. Nothing you said was flawed, but your ability to adapt to my refined assertions were dreadful. And so you lost. Good try though!

Heart of Gold clip to windward
Jeff, remember that saying about teaching pigs to sing?
Scotty "Jeff" wrote in message . .. Capt. Rob wrote: ... Totally irrelevant. You might have something if he had a hand picked crew, new hi-tech sails, a fresh bottom job, and you lost the A/C. Well, now we're getting somewhere. My boat has the AC, but she's currently stripped out for the end of season cleaning. No water in the tanks, gear and even the anchor removed. My bottom is clean and my tired sails are less of a factor when I'm not hard on the wind. So you're saying you were not "hard on the wind"? And yet you exceeded the optimal VMG to Windward by 15%??? You still don't understand. But boats don't suddenly gain 15% over their optimal VMG to windward just because a competent hand is on the wheel. Calling this fellow competent is like saying O.J. Simpson needed a little therapy. He's a fairly top notch sailor and very respected in this area. Good for him. Doesn't change anything. You're simply mis-using the terms. Yes, it is. You just don't get it. Its like Road & Track said a certain car did the quarter in 5 seconds, and you claimed you did it in 4 seconds. In the snow. Not at all. And Road and Track has gotten a second more/less on cars compared to other rags. Such tests, along with Polars are rough estimates at best. By "rough" you mean off by a few percent. Not 15%. The biggest variance comes from sails, because the new technology can go beyond the assumptions of the VPP. However, if your sails are old, you loose any advantage there. And you've already admitted you weren't pointing at close to the optimal angle, so you lost any extra pointing ability. For example, my friend "claims" that he clobbers the published polars of the J30. "Clobber" going upwind means beating by 2 or 3 percent, not 15%. And he probably meant off the wind. This is another point you fail to grasp. While some boats can frequently exceed their "theoretical limit" off the wind, upwind it is much more difficult to beat. I grasp that, but your whole argument still hinges on polars made up when the boat was first designed and tested...more than 18 years ago. Optimal trim and sails were yet to be found. In fact, previous owner of 2 35s5's and Heart of Gold, Arthur Rodriguez said that Beneteau had the 35s5 main all wrong and recut it for better upwind performance. Mark P, at Doyle is looking at the cut of my main next week on this very issue. Actually, my argument hinges on the fact that the polars of almost every boat your size has an optimal VMG to Windward of well under 6 knots. Further, you claimed that you weren't even going upward, that you weren't hard on the wind. Further, you even claimed that the mark used for the VMG measurement was off the bow. And finally, you're claiming that the VMG was measured with GPS, and a handheld unit at that. All of these thing contradict your claim. Further, upwind performance to not vary very much between boats of the same style. Boats simply don't suddenly go 15% faster than predicted. In PHRF terms, this is like suddenly going 100 points faster than then rating. That's an exageration. No. Its not an exaggeration, its called basic math. At 5 knots you're doing 12 minutes per mile, or 720 seconds. At 6 knots, that's 600 seconds per mile. That's a difference of 120 second per mile, which translates directly into 120 points on the PHRF rating. Maybe its a bit less if you really get 5.2 knots, but its still up near 100 points. So what you're saying is that a quality skipper can make a Westsail 32 go upwind faster, that is, get better boat speed, than an average skipper on a 35s5. The 35s5 will stay with newer 1st boats upwind as reported by owners. Her weakness is in the downward leg. Even the deep keel does poorly dead downwind. It can stay close because in fact the differences are pretty small, only a few tenths. So when you sail nearby you can deceive yourself into thinking you're going almost as fast. The other day you said any Benny First would "smoke" an Ericson 35-3, when in fact your boat only has a couple of points on the Erikson. So when it suits you, 2 points is huge advantage, but now you're claiming that a proper rating for your boat should be around 30. It's funny how you lie again and again and nobody calls you on it. But I will. I NEVER said my boat would "smoke" a E35 Mk3. Sorry, you didn't say "smoke," you said "toast": "As you might know, 1st series Beneteau's will toast any Ericson 35. The III from Bruce King was a fast boat, but 1 & 2 were pretty slow. The Mark III version is still outrun by the older Beneteau 1st 345 for example" So who's the liar? In fact the rating for the Ericson Mk III is 123, SD is 132, the Benny 345 TM is 120, and the 35s5 TM WK is 123. These are all pretty close, only a few seconds a mile for the comparison you said would "outrun." I said 1st series Beneteau's are faster boats and that the E35 would have a hard time sailing around even a slow cruising Beneteau. You'd need a Mumm 30 for that! But Bart's silly post went unchallenged until I pointed out how dumb it was. Actually, we all assumed he was talking about the sailing ability of Benny owners, but you seemed to have missed that. Yes, I remember when a friend who was the local Star champion came on my Nonsuch and started playing with the sail twist. He made the boat perform close to the polars, not exceed them by 15%. Do you REALLY think this is a valid comparison? Your comparing a Nonsuch with a 1st 35s5 with a far more tunable and variable rig. If he only came close to the polars, then he must know have known how to sail your boat. Actually, if you knew anything, you'd understand that the Nonsuch rig is quite adjustable. Why don't you explain to us how often you adjust your outhaul or topping lift while underway? I tweaked mine at every point of sail. He probably told the truth. You, being a simpleton, misunderstood. He told you the VMG to a mark 10 degrees off the bow, that is not the VMG to Windward. Actually, when I asked him our speed, he clearly said 6 knots. I then asked what the VMG was and he repeated six knots and that our speed was showing over seven. He was impressed and so was I. The mark WAS to windward at this time. But again, and I'll state it again because you can't seem to accept it...we were NOT beating. The video clearly shows this as we are not sheeted for close hauled sailing. Perhaps I should be more explicit: The mark has to be directly to windward. Not slightly to windward of your centerline. There is a huge difference. And one more time you're claiming that you weren't even close to the wind, you weren't sheeted in, and yet you were going upwind faster than the polars predict! You really don't understand the meaning of these words, do you? His GPS does NOT report the VMG to Windward. This is the issue here. In order for the GPS to do that, the mark has to be directly to windward, preferably far away. Sigh. indeed. You told us it was nearby, off the bow. I gave that as an example for the 3rd clip, not the second. Can't you keep track of 3 short videos? The mark to windward was a bouy on the second clip/ So what was it, directly upwind or 10 degrees off the bow? You said: "We have a mark set on the GPS about a mile off and we're on a starboard tack (again, for example). Now, the mark is about 10 degrees off our starboard bow. GPS is reporting our VMG fluctuating between 5.6 and 6.1 knots as we close on the mark. " This sure sounds like it was not directly upwind. Nor was it far away. Everyone always assumes that everything you say is a lie. Yup...I lied about buying a 35s5, about sailing it 3-4 times a week, about pretty girls aboard, about shackles on the dock, even about selling boats and doing sea trials. And yet each was backed with pics and even video which drove people like you out of your skull. Even when I said Bob L. trimmed the main a few minutes later...BAM, you get a pic. You all tell stories. Big fish tales. I have documentation of my modest sails. I fish for you all here, but you should see the e-mails I get. Most people who come in here think the rest of you don't even have boats! yada yada yada. I'd rather you took a course on basic sailing so we wouldn't have to explain the simple concepts to you over and over again, You think they'd teach me that a close reach isn't to windward? That WAS your claim before you backpedalled like Lance Armstrong from a testicle biopsy. So once again you're claiming that even while on a close reach you had a faster VMG to Windward than the polar predicts or the touted review. You simply don't understand the meaning of the terms. Jeff, you really need Gilligan's help on this. Gilly has gone over to the dark side! |

Capt. Rob wrote:
So let's see one that was done in the last 15 or 20 years that was off by 15% in upwind prediction. What you're claiming is that Beneteau shipped a boat that the polars predicted was as slow upwind as a Westsail. 35s5 owners claim to beat the polars by 7-10%. Show me one such claim. And we're talking upwind, here, not off the wind. If this were upwind, it would be an improvement of 50-70 points on the PHRF What course is that? You're the one who doesn't know what course he was on. I've only said it doesn't matter. You keeping begging for the exact course, but it doesn't matter? Oh. Why do you think it matters? I only ask for the course so I can provide a more accurate value for the VMG to Windward. I've already given the formula: VMG to Windward = cosine(angle to the true wind) x speed through water. I'm not demanding anything. I've only suggested that any sailor who was on the boat at the time might know what point of sail the boat was on. Roughly between 50-60 degrees. How's that? At 55 degrees, a speed a 8.5 yields a VMG of only 4.8 knots. And that doesn't count leeway. That does not appear to be true. You can't tell us the point of sail. Probably because I was enjoying myself and shooting some nice vids for the group. Someone else was sailing. But I gave you a ROUGH estimate. Actually you said it was directly to windward. Nope, never said that...and if I construed it as such it's wrong. The mark was to windward, but not directly. Except for the time when you said it was 10 degrees off the centerline. For clip #3, yes. Not what we're talking about. I never figured out your number system. No, but they don't help that much. Oh my! Why should they help? Other than demonstrating that you weren't close to the wind, but you had already stated that. Since you gave upper limits for how high you were pointing, and how fast you were going, there was no further info needed. I trust them, within their limitations. But then even you must essentially guess at those. By and large modern instruments are pretty good and mine are newer than yours. Are you sure? How old are mine? When you never leave sight of your slip you don't have to learn how your instruments work. You can't see my slip from Execution rocks. Its only three miles. I'm sure that's very scary for you, Bob. Actually, IIRC Hart Island is not very high, you can probably see your slip from the masthead, or maybe with the radar. You can just make up numbers to impress your "friends." And show a video that impressed them even more....though it upset you for reasons we all understand! I hardly looked at the videos at all. You seem to be obsessed with them, but they really weren't that good. I reacted entirely to you obvious blunder in using the term "VMG to Windward." WRONG! Ask any sailor with experience. "VMG to Windward" has a very specific meaning. But I clearly made it clear so it would be clear that I was refering to a mark windward of us. How many times can I say it? You don't want to listen to that because then you have nothing left to stew about. And when I said that that doesn't work unless the mark was exactly to windward you then said it was. You screwed up. You didn't know the meaning of the term. You're now trying to weasel out. You're Busted! You keep saying that. And that's why it is impossible that your VMG to Windward was 6 knots. See above, genius. You really are arguing a point based on something I never said. Of course you said it. Its right there, in your first post: "to windward at just over 6 knots VMG." That only has one meaning to a sailor. I know what VMG to windward means, but I was talking about a mark windward of us. No, now you're obviously lying. The only backpedal here is YOU refusing to acknowledge this little point. Why would anyone misuse a precise term so blatantly? Its very clear you didn't understand the difference. You had plenty of time to correct it if it was a misunderstanding. No, you screwed up and now you're lying to to cover it up. Our VMG to the mark, was 6 knots. We were on a windward tack to get there. Can't you figure this out? Three people e-mailed me and THEY understand! Sheesh! Bull****. You're lying again. They may have understood that you were confused and misused the term. No competent sailor says "to windward with a VMG of 6 knots" when they mean a VMG to an arbitrary point. Its a meaningless statement. The concept of directly is implied by "to windward at just over 6 knots VMG." If you hadn't said VMG, it would have been understood as speed through the water by most sailors. But by using "VMG" and "to windward" together, you imply the VMG directly into the wind. Except that I then made it clear that I was sailing for a mark. AGAIN! Oh boy! And yet, when I insisted that the mark had to be directly to windward you said it was. I inferred exactly what every sailor would infer. Do you think any sailor would continue to make such an inference based on the facts as I gave them? Would they basically choose to ignore the fundamental details? Would they just get it as mind bleedingly wrong as you have??? I hope not!!! What facts? What details? You didn't know the course, you seemed confused about where the mark was. First off the bow, then directly upwind, now somewhere else but you don't know where. and essentially admitted that you didn't understand the fundamental concept. More lies from Jeff the Drunk. Please provide the link to my comment! Its right here in this post. You're now claiming the VMG to Windward doesn't mean directly into the wind, it can mean to some random point somewhere upwind. I can certainly find numerous references that support my side, can you find a single one that supports yours? Every book on yacht design uses VMG almost exclusively to mean either directly upwind or directly downwind (actually, they are the same, just a sign change). Ooops! You've just opened up another area where you can demonstrate ignorance. Here's a hint: your wing keel does not improve your performance to windward. It allows you to have performance almost as good as the normal keel with a smaller draft. Not too many boats have better upwind performance with a wing keel than with a deep keel. BZZZZT!!! A perfect example of why you're losing this debate! I never said it outperformed the deep keel version. The Deep keel sails 3-4 points higher and has less leeway. Once again you infered idiocy conjured from your own depths. I simply said the wing does a good job, which it does. A wingless 4.9 draft of the same boat would not perform as well. And by the way, owners that have sailed BOTH versions have claimed less leeway with the wing on a reach all the way to a close reach. Heresay, but there it is. A complete performance package report (not just the polar part) would tell, but the difference would be pretty small, I'm not sure how any owner could actually detect it. The leeway on a beam-close reach would be in the order of 2-3 degrees, so to claim one is better would imply measuring a difference of maybe one degree or less on different boats with different sails and setup. How can such a comment be meaningful? You implied that because of the wing your boat has less than normal leeway; that's simply not the case. Nonsense. Its a pretty gross error. There's almost no 35 footers that can do 6 knots "VMG to Windward" while on a close reach. Luckily I never made such a claim. You DID! Gee, you made the claim that you were going "to windward at just over 6 knots VMG." And you showed a video, and then verified that you were on a close reach. Sounds to me like you made the claim. And since you're not claiming extreme speeds, its a physical impossibility. Just like beating hull speed. Guess why there's so little support for you on this, Jeff. Because most folks with experience know polars are often topped by significant margins. No support??? Every other person who has contributed to this thread has taken my side. Maybe someone else will jump in and claim they frequently exceed their upwind polar by 15%, for more than a few seconds. I'm waiting. I was very specific about the meaning of "VMG to Windward." And I was VERY specific about my comment and what I meant. Yes. And you had it wrong. Much later you tried to change it. Why choose to ignore it? So you can argue about an intangible event? And let's not forget that you now claim I wasn't even aboard! You sure are working hard for someone who doesn't care! Wanna get on the phone and talk about it? No, I'm happy to have everyone watch you embarrass yourself. You must know that every claim you make in the future is tainted by your blunder here. They only serve to show your ignorance, such as labeling a shot when you're on a close reach as "windward work." Yep, I guess that was downwind work! And again you mis-use a common phrase. Every sailor would understand "windward work" to imply going upwind, not reaching slightly higher than a beam reach. You have to sail another 50,000 miles or so to catch up to me. I'm 43, Jeff. Lots of time and boats and sails ahead. And if we just count to on the boat away from the dock, you don't even come close to me nowadays. For instance, I've averaged 70 full 24 hour days a year on aboard for the last 14 years. You probably don't do 70 day sail Again with the lame "I sailed further, slept aboard and cooked brownies in the boom" crap. Play with your toys as you please. And I will. You're the one who insists that surely everyone must be envious of you. Personally, I don't envy your boat or your sailing area, and given a choice between daysailing 4 or 5 days a week, or cruising 6-7 weeks every summer with an occasional full year cruise, I'll take my life style every time. Your VMG of 6 knots was clearly bogus from the beginning, simply because this is extremely high, especially for a 35 foot boat. And you're still wrong, Jeff. Because you've built your position on ignoring the facts. And what fact is that? The only defense you've stated is that you mis-used the term "VMG to Windward." Stupidity is not a great defense. Everyone except knew that, except for you. Huh? Dude, calm down. Take a pill!! And you should have realized immediately that any VMG described in your conditions clearly could not be the correct VMG to Windward. Which is why I explained we were heading for a mark which was upwind and our VMG to that mark was 6 knots. NOTHING you're saying contradicts this. You're hanging onto the "VMG to windward" term for dear life, but you KNOW that's not what I was talking about. You've known it for 20 posts and yet you still prattle on. Of course I knew that's the mistake you were making. I claim that you didn't understand the difference until someone explained it to you last night. I think I have a great understanding of VMG. In fact, anyone with some clear understanding would have known what I meant. But even after I explained it...as if you're a two year old...you STILL can't grasp the events! The event is simply that you mis-used a very precise and commonly used term, and failed to see your blunder for about 20 posts. What numbers fail to support me? All of them since you've created an event for my boat that I never described. "In clip #2 it's directly to windward. Do you know what that means?" THAT STATEMENT is in error. I meant that the mark was to windward. In other words, when the essential issue was whether the mark was directly to windward, or just somewhere to windward of the course, you got it wrong and then failed to correct yourself. It sure looks like you really didn't understand what was going on here. That certainly sounds like you were saying "directly to windward" to me. So now you're going to claim that "directly to windward" does not mean in the directly from which ... Nope....and again I think you clearly understand what I meant and I was clear that I was sailing on a windward course for a mark at 6 knots VMG. Your original post did not mention a mark. When you then mentioned a mark I assumed it must be a distant mark directly upwind. You don't want to admit to that because it destroys all of your hard work here! But it's much appreciated, Jeff. Last night I looked up a lot of polars online and refined my understanding of them. Actually, why don't you share them here - I always like to check them out. Now seriously, dude. Calm the F down! I'm sorry you lost this debate. Nothing you said was flawed, but your ability to adapt to my refined assertions were dreadful. Especially when you insisted the mark was directly upwind. We're still waiting for any reference that supports your claim that "to windward with a VMG of 6 knots" would commonly be taken as anything other than "VMG to Windward." Until then, this is a big win for me. |
