Sure, it must be better because it points higher.
Of course, he can't use the head while underway! This could explain why he claims that past Execution Rock (3 miles from his slip) is "deep into the Sound"! Going any further would be horrific!

He's beating to windward @ 36° making 4.7k - decent performance. But, you, with your loaded-for-cruising slug that can't point, foot off to about 50°, but in doing so are holding 6.5k. Yeah, you're faster, but you're not pointing. Then, down wind, he's sailing 170° making about 4.5k and you reach off to about 150° and are making just over 6k. Again, you're faster, but he's sailing closer to the mark. Can't you just accept the fact that his boat is better because he can point higher? S. "Capt.

Throwing the helm over just applies the brakes. So in a sense, a cat will maintain speed better than a monohull that crosses the wind like a buffalo (the correct spelling--perhaps you should use "ta tonka" instead--easier to spell) wallowing in the mud. Second, he's not thrashing anyone unless he has conditions and wind to do it. This is true of just about any boat in existence. No boat does well in all conditions. For example, Mooron's boat would give yours a thrashing in 20kts. or better. The better pointing boat is the better performing boat. This depends strictly upon the usage or task at hand. In around-the-buoys racing the higher the ability to point the better. In extended cruising it may be meaningless. So it has been and always shall be. Are you having delusions of godhood again, Bubbles? Tacks on the upwind even in reasonably fair conditions off a 10 degree deficit? Do you know how that would effect his VMG versus a high pointing monohull? I'd suggest you take the time to read Ted Well's book "Scientific Sailboat Racing" and learn something about the art of pointing. You obviously are clueless. And what of the more common light air? PDQ 36 is a cruiser with a very fast off the wind ability, but a performance boat it aint. Compared with a J120, your boat, too, is a slug. Everything's relative, Bubbles. Max |

Then how come so many folks can afford a Multi and don't have one? Where's your multi? Where's mine? Where's Loco's? How come Doug says he's looking at a C&C and not a multi? Where's Bart's multi? Ganz seems to want one. Not me. Someone has to speak up for the group during hard times. Do you want a boat that is "tedious to tack?" Do you want a boat that "won't point higher than 45-50 degrees"? I am the chosen one, Skywalker! RB 35s5...the top performing boat here! NY |

The single biggest problem with cats is that they're expensive. While there are lot of small cruising boats for $20K, its hard to find a good cat used for under $80K. And since the smaller ones don't work that well, the entry for a true long distance cruiser is well over $100K. Where's your multi? Where's mine? Where's Loco's? How come Doug says he's looking at a C&C and not a multi? Where's Bart's multi? Ganz seems to want one. Not me. So how many have said your boat would be their first choice? Someone has to speak up for the group during hard times. Hard times? Is that what you call it when you buy a boat? Do you want a boat that is "tedious to tack?" Do you want a boat that "won't point higher than 45-50 degrees"? Hopefully you did, because that's what you bought! If you wanted to point higher without pinching, you would have got the deep keel! I am the frozen one, Skywalker! RB 35s5...the top performing boat in my slip! NY |

Then how come so many folks can afford a Multi and don't have one? 1. limited availability of slips beamy enough to accommodate cats 2. no experience with cats, therefore they buy what they know 3. very few cats available in some regions of the planet 4. many of the good cats are made in France :-) 5. many of the cats available in the USA are ex-charter boats, and rather well, um . . . *used* 6. good quality cats generally cost about 20-50% more than equivalent-sized monohulls 7. cats, being a rarity in some areas, are perceived as difficult to resell need more?

But the tradition of sailing is what most of us prefer, and that included healing and the most important thing of all....Upwind ability where a multi faulters 10 degrees or more away from a boat like mine. On a long reach Jeff's boat is faster, but in any real race on various tacks, the PDQ couldn't even STAY ON the course. Finally admitted??? I finally admitted that cats don't point well??? And that's thats the best you've got? Booby, have you ever heard of VMG? Pointing ability is only one component of going upwind, speed is another. We don't have the polars for either of our boats, but we can make some guesses. Here's the polar for a Beneteau First 407, designed by Farr, and a much better upwind performer than yours: http://www.1stsailing.com/Boats/BoaI...hnicalData.jpg Speed at 45 degrees true tops out at a bit over 7 knots. Multiplying by the cosine of 45 degrees (0.707), we get a VMG (Velocity Made Good) of about 5. The Benny can point a tad higher, but if it loses even half a knot the VMG drops. The actual optimum point may be 40-42 degrees but there is actually very little difference between that and 45, except on the race course where pointing can be a tactical advantage. So how does this compare to a 35s5? The 407 has PHRF of 57 compared to around 130 for the smaller version, so that's over a minute a mile or at perhaps 10% on VMG. So the upper limit of VMG for the 35s5 might be 4.5 knots. Now, how about a cat? If we foot off all the way to 60 degrees true, VMG will be half of boat speed, so we have to do 9 knots, which the PDQ will do in 18 knots. Of course the comment of 60 degrees is fairly approximate, if the optimum is actually at 55 degrees, then the cat only has to do a bit over 8 knots to beat the monohull. Its pretty clear that in a breeze, the cat can keep up with, or even beat a Benny upwind. In lighter air the cat's speed will drop off faster, so upwind the cat will fall behind. But this is only part of the story. We haven't factored in leeway. The Benny may point at 45 degrees, but what's its actually course? Heeled on its ear, its making at least 3 degrees of leeway, considerably more if its puffy. At 3 degrees the hit to VMG is 5%, at 5 degrees the hit is over 10%. In fact, on a puffy day, it takes considerable skill and attention to get the most of the Benny. The cat, on the other hand, will be going flat and fast at 60 degree true, with minimal work. A number of times we've blown past a mono stalled out in a puff, heeled over, making maybe 15 degrees leeway, sometime worse. So what's the true break even point? It would depend a lot on the conditions. In protected fla****er and steady wind, it might be 16 knots, add a chop and puffs and it might be 12 knots of wind. With a full crew in a race the benny might do better; shorthanded the cat is easier to keep moving. On a small race course, a mono certainly has a tactical advantage, but remember that the small version of my cat races at a PHRF equivalent of about 104. This is before we take into account Bob's primary claim, that most people prefer a boat the heels and goes upwind as fast as possible, especially in light air. Frankly, I don't care what "most" people prefer, I only care what suits my needs. Certainly, if your sailing is limited to a few hours of daysailing, its understandable that you want to get the most "sailing" out of it. In fact, I sail at a local club where I can take out a racing dink, or more likely a Rhodes 19, so I can do some daysailing and get the real "experience." But my purpose in having a larger boat is to go cruising, which usually means traveling 100 miles or more to interesting destinations. I have no desire so spend a whole day heeled over 40 degrees, or making 2 knots VMG upwind in light air. In fact, I never heard a cruiser say they want to heel more, and there are rather few that will "take what comes" and wander around in a drifter. Go ask at any cruising anchorage and you'll that 90% of the would prefer to sail flatter, and most would fire up the engine when the VMG goes below half of their normal "good" speed. So...in Jeff's OWN WORDS, ladies and gentlemen... I know what I said, and stand by it. Does Bob know what he's talking about? Doubtful. And so...with winds below 10 knots MANY times in MANY areas, the PDQ gets an engine workout. So would many other boats. Do you have a point? Cruising boats often don't do well in light air??? What a revelation!! With limited upwind performance the engines get another workout. 45-50 degrees is NOT ACCEPTABLE. Then you better get rid of your Bendy, because it doesn't do significantly better than 45 degrees. You really don't know anything about sailing, do you, Bob? I bet newer multis manage better. Sure, lots have daggerboards. In fact, you could buy my boat with daggerboards. I didn't have that option at the time, but it isn't something I would want to sacrifice convenience and interior space for. Raising the VMG from 2 to 3 knots doesn't mean much - I've freely admitted I probably be powering at 8 knots in that case. And so would most other cruisers. On the LIS these boats have to be motored much of the time and these are otherwise classic sailing grounds hosting some great sailing events. We see few Multi's sailing and for good reason...sooner or later you need to sail upwind better than 50 degrees! Gee, do you think maybe that's why I said this boat is an appropriate choice for you? I'll say it again: A Beneteau 35s5 is possibly the best boat for someone who only sails 5 miles from his slip in light air. Are you happy now? RB 35s5...the best performing boat on LIS, but not anyplace a real sailor would want to be! NY |

"It won't point too high (45-50 degrees true) but it will go upwind side by side with any cruising boat. Foot off 5 to 10 degrees, and it takes off like a bandit. Tacking is tedious, it certainly isn't good for short tacking out a channel. Light air is another sore point, because the large wetted surface starts to dominate. However, in 10 knots and over will do about half the wind speed. It continues to hold this ratio up to 12 to 15 knots of boat speed, depending on how long you hold off on reefing." And so...with winds below 10 knots MANY times in MANY areas, the PDQ gets an engine workout. With limited upwind performance the engines get another workout. 45-50 degrees is NOT ACCEPTABLE.

NY The fact that every record in ocean racing is being set by multihulls kinda pokes holes in everything you say. It doesn't matter how high you can point if you go twice as fast 10 degrees lower. Where I race, in light airs or big winds the first boat home is always a multihull. Gaz |

I raced a Snipe with a sailing club that for years had Snipe, MC-Scow, and Hobie 16 fleets. The general rule was that if the air was very light to dead calm, the cats would be started behind the monos. If the wind was 5 kts. or better, the cats were started first. I recall races in which the cats were started behind the other two fleets, only to have the wind freshen subsequently. The Hobies would then blast through the other two fleets and be back on their trailers before we made it back to the club dock. Max |
