There really isn't a lot of difference in weight. Not sure I'm following you here Jeff. In your previous note, you stated: that: "And, as I said, with that large engine hanging off the stern there's a huge amount of weight back there." - So which is it Jeff? - A "huge amount of weight back there," or "not really a lot of difference in weight." If the latter, wouldn't that tend to counter your arguments about the motor and ballast messing up the handling of the boat during pitching movement? I was simply responding to your claim that the weight of a 50-70HP outboard is "far less than the weight of a typical diesel." In fact, its about the same weight. Jeeze, Jim, do you really feel the need to fight tooth and nail on every issue, including those where you're completely wrong? Is this a lawyer thing - do you get paid the same even when your arguments are stupid? And let me point out again, its not the weight, its the location. A 250 pound engine hanging off the stern contribute far more to the pitch moment than an inboard close to the center of the boat. My boat actually could accept large engines - the builder put twin 100's into the smaller version of it, and with only minor hull mods, created a best selling powercat. But this formula does not work well for monohulls. I understand that you have a 36-ft cat. Quite a bit larger boat. - What's a typical cruising speed? 7.5 to 9 knots in most conditions, though in a breeze its seen 13+ knots. The powercat with twin 100's cruises at 16-18 knots, using only 4 gal/hour. They originally offered smaller engines, but found the big ones actually had better efficiency, so there was little point. So you say. Why is it that you almost never post a trip report? What, exactly, would you like to know? I had the boat out Saturday in 15-knot winds with fairly rough chop and some whitecaps, and the boat handled steadily and smoothly except for hitting some nasty wakes of large speedboats. As mentioned above, I was thankful for the larger motor when going out against the wind and chop. Under sail, we were heeling about 20 degrees fairly consistently with one reef in main, and the jib rolled in slightly. Lots of other boats on the water, substantially larger than mine for the most part, and quite a few of them flying only one sail. Coming back, the Mac motored through the chop at over 13 knots quite smoothly. This was an afternoon sail in Galveston Bay, not an extended cruise. Sounds like fun. Might I remind you that a few years ago you were insisting the Mac could do 18 knots while I was saying that was unrealistic, you probably wouldn't do much over 12. ... Now, where is your last trip report? No reports this summer, my spare time (and a chunk of the cruising time) got preempted by family issues. However, here's the most recent set of pictures: http://www.sv-loki.com/Summer_06/summer_06.html In years gone by I've posted a few reports each summer, such as this one: http://groups.google.com/group/alt.s...994c6e8d4fd9bf or this: http://groups.google.com/group/alt.s...4bf089a2629977 If you want to see a long trip report, here's two.

Either you're too stupid to follow the discussion, or you just showing what type of lawyer you really are. Obviously the boat was designed to float on its lines with full ballast and an engine. The issue is whether a different distribution of mass would lead to a boat that sails better. Actually, the motor isn't much more astern then the crew sitting in the cockpit, or the skipper sitting on the back seat over the transom. If a 4000 lb racing boat boat sailed with one large (250 lb) crew hanging off the stern, and another standing on the bow, it would be substantially slower than its competitors.

I thought I just gave one. The weight of a 15 Hp Yanmar, including everything (alternator, pumps, filter) except the shaft and prop is 249 lbs. Clearly one might add another fuel filter or water filter, and the muffler weighs a few pounds (mine are plastic) but all of this is only a few pounds, and then your outboard also has a few extra bits and pieces not included in its base weight.

Yes, buts that's been my point. If you want to keep the boat very light, and are willing to forgo ballast on a flat clam, you can achieve the high speeds. But you've just proven my old point that loaded up with a bit a gear, and dealing with a bit of weather, you won't want to go that fast. Very nice. Beautiful little girl, and dog also. I suppose you can anchor in fairly shallow water also. I'm in the same area as Joe, between Houston and Galveston (third largest number of pleasure boats in the US). I don't think our harbors and anchorages are as nice as yours, although we can get to the gulf in a few hours. I've only sailed on the FL side of the Gulf - I enjoyed it a lot, the Naples area has been on our short list of possible places to move to in a few years.

(I think that's because the forces of "wrong" can afford more of them!) If there are lawyers representing both sides, how can more lawyers be on the "wrong" side? - Some of them must be on the "right" side. Regarding my particular specialty, I was an intellectual property and licensing attorney, not a trial lawyer. Our legal system has problems, and I'm not defending it, except to say that most cases are settled more or less equitably without going to trial. - It's the outrageous ones that get the publicity, not the other 95%. Sort of like the rest of the news - everyday hard work and ethical standards isn't newsworthy. And let me point out again, its not the weight, its the location. A 250 pound engine hanging off the stern contribute far more to the pitch moment than an inboard close to the center of the boat. Well, that's clear enough, and I agree. But once more, the boat is built to be balanced fore and aft with a motor and a crew in the cockpit. And it is. Totally irrelevant. Nope. It's actually quite relevant. The boat is built to be balanced, under sail or power, with the motor and a typical crew in the cockpit. It's built to sail and motor as efficiently as possible with the compromises inherent for it's intended use. In general, it's well balanced,it doesn't "pitch" excessively, and it is fun to sail. Either you're too stupid to follow the discussion, or you just showing what type of lawyer you really are. Obviously the boat was designed to float on its lines with full ballast and an engine. The issue is whether a different distribution of mass would lead to a boat that sails better. Maybe it would. But it's still a lot of fun to sail as it is. (I'm repeating myself, but isn't that the point, after all? The reason I bought the boat is to have fun sailing it, not to race it.) Also, I believe that the new 26M hull is more efficient for sailing, and smoother when plaining(though perhaps not quite as efficient) as the older model. Actually, the motor isn't much more astern then the crew sitting in the cockpit, or the skipper sitting on the back seat over the transom. If a 4000 lb racing boat boat sailed with one large (250 lb) crew hanging off the stern, and another standing on the bow, it would be substantially slower than its competitors. (Not to mention being more uncomfortable.) So, what's your point. The 26M was built as a family cruiser, not a racer. Most racing boats in this size range wouldn't be as comfortable or as roomy or as versatile as the Mac. Plus, it's lots of fun to sail. However, I don't think I agree that a typical diesel, with generator, fuel pump, filters, prop shaft, etc., would weigh about the same as a modern outboard. - Any stats on that one?

Also, since the diesel generates almost twice the power from a pound of fuel, one can claim a huge weight advantage on that front. That's more than my 50 hp weighs. Also, add the weight of the drive shaft, the drive shaft bushings, the mounting hardware, the reinforcements to the hull supporting the motor, etc. Sounds like fun. Might I remind you that a few years ago you were insisting the Mac could do 18 knots while I was saying that was unrealistic, you probably wouldn't do much over 12. Here's the quote to which you apparently refer: "JAX, did it ever occur to you that some owners of cruising sailboats may take them out to enjoy a pleasant day of cruising with friends or family from time to time rather than racing their boats? If I'm taking my family or grandkids out for a day on the water, there may actually be times when I sail the boat with everyone sitting in the rear and with less than optimum balance and sail trim. - Shame, shame on me! On other days I may want to take more care in adjusting the sails and balancing the distribution of weight in the boat to get as much speed as possible. (Like, planing the boat at around 12 knots under sail, or 18 knots under power.) The bottom line is that some of us sail for the pleasure of it, and some of us go sailing as a competitive sport, so that they will be able to brag about winning a race or sailing by several other boats. I enjoy both aspects, but I recognize that the Mac isn't a J-boat and isn't designed as a racer. So I don't expect to pass many large displacement boats" Incidentally, in notes on the MacGregor discussion groups, speeds of over 20 knots are being reported when sailing without the ballast, and with a larger motor. - I personally haven't wanted to motor without the ballast so far, but I'll give it a try this Spring. This particular day was fairly rough, and I wasn't running the motor full throttle. - I still think the boat would motor at 18 knots on a smooth day without the ballast. - But I haven't seen those speeds yet, because I've been reticent to motor without the ballast.

I was still doing substantially more than any other sailboat on the Bay, and there were plenty out there. (And as mentioned above, I didn't have the throttle wide open.) Very nice. Beautiful little girl, and dog also. I suppose you can anchor in fairly shallow water also.

Half the time you claim your boat is fast, the rest of the time you claim your boat is slow but you don't care. This discussion was specifically about how the distribution of mass affects stability and performance, and all you shown is that you have no concept of these matters, nor do you care. However, I don't think I agree that a typical diesel, with generator, fuel pump, filters, prop shaft, etc., would weigh about the same as a modern outboard. - Any stats on that one?

Also, add the weight of the drive shaft, the drive shaft bushings, the mounting hardware, the reinforcements to the hull supporting the motor, etc. Yes, we know that the mac has no reinforcements to the hull supporting its motor. You really are intent on showing how lawyers lie, aren't you? You made the claim that a diesel is much heavier than an outboard, and that simply isn't true. Further, the issue has nothing to do with the possible difference of 20 pounds, it has to do with the distribution. And BTW, the diesel appropriate for a boat as light as yours would be a single cylinder, which would weigh just about the same as your outboard. Sounds like fun. Might I remind you that a few years ago you were insisting the Mac could do 18 knots while I was saying that was unrealistic, you probably wouldn't do much over 12. Here's the quote to which you apparently refer: No, that wasn't the specific quote, but it was one of several. Actually, I objected to the claim that the high speeds could be used when returning in bad weather. Given all of the warnings about running at high speed or without ballast in chop over one foot, this appears unrealistic, if not impossible. Incidentally, in notes on the MacGregor discussion groups, speeds of over 20 knots are being reported when sailing without the ballast, and with a larger motor. - I personally haven't wanted to motor without the ballast so far, but I'll give it a try this Spring. There is no doubt that it can be fast in flat water and unloaded. Of course, put that engine on a proper powerboat and you'd do about 40 knots, so what's your point? I was still doing substantially more than any other sailboat on the Bay, and there were plenty out there. (And as mentioned above, I didn't have the throttle wide open.) yada yada yada bragging that you can power faster than sailboats. impressive. |

It seems to be in their blood. Jeff, I don't have time to defend lawyers on this ng. - I hardly have time to discuss the Mac. But I do remember that the usual quote from Shakespeare - "The first thing we'll do, let's kill all the lawyers" was from the thieves and robbers who didn't want lawyers interfering with their "businesses". And let me point out again, its not the weight, its the location. A 250 pound engine hanging off the stern contribute far more to the pitch moment than an inboard close to the center of the boat. Well, that's clear enough, and I agree. But once more, the boat is built to be balanced fore and aft with a motor and a crew in the cockpit. And it is. Totally irrelevant. Nope. It's actually quite relevant. The boat is built to be balanced, under sail or power, with the motor and a typical crew in the cockpit. By "balance" I meant that the hull, motor, ballast, and sails work togther to cause the boat to to sail and motor as efficiently as possible under a variety of applications. In general, it sails and powers well, it doesn't "pitch" excessively, and it is fun to sail. And once again, you prove my point that you will blatantly lie in order to claim that, as you say, you "seldom loose." The issue has nothing to to with "balance," it has to do with distribution.

The issue is whether a different distribution of mass would lead to a boat that sails better. And just how would you redistribute the mass, Jeff? - Where would you move the outboard, and where would you move the ballast? The 26M is the result of years of development, feedback, and mods. It does a lot of things most sailboats can't do. If serves the needs of most sailors, under the conditions experienced 90% of the time. It's relatively inexpensive, if you are willing to compare the costs of new boats to new boats, or used boats to used boats, and not compare the costs of 15 year old boats with that of a new Mac 26M similarly equipped. And, (I almost forgot) it's a lot of fun to sail. Maybe it would. But it's still a lot of fun to sail as it is. (I'm repeating myself, but isn't that the point, after all? Is it? Little children think picking their nose is fun, is that your standard? You fight every detail tooth and nail, even when you know you're wrong, and then you say "it doesn't matter that I'm lying because I'm having fun." Jeff, we may have differing opinions, and you seem to have confused your own opinions as facts, but would you please name the more egregious instances of my lying? Perhaps you could list the top ten instances? The reason I bought the boat is to have fun sailing it, not to race it.) Also, I believe that the new 26M hull is more efficient for sailing, and smoother when plaining(though perhaps not quite as efficient) as the older model.

This discussion was specifically about how the distribution of mass affects stability and performance, and all you shown is that you have no concept of these matters, nor do you care. The boat is fast enough to be fun to sail, Jeff. It's not as fast as some other boats, but it's still fun to sail. - Isn't that the important factor.? (Actually, I wasn't having too much problem keeping up with some, though not all, of the larger boats on my last cruise.) However, I don't think I agree that a typical diesel, with generator, fuel pump, filters, prop shaft, etc., would weigh about the same as a modern outboard. - Any stats on that one?

Also, since the diesel generates almost twice the power from a pound of fuel, one can claim a huge weight advantage on that front. That's more than my 50 hp weighs. Also, add the weight of the drive shaft, the drive shaft bushings, the mounting hardware, the reinforcements to the hull supporting the motor, etc. Yes, we know that the mac has no reinforcements to the hull supporting its motor. You really are intent on showing how lawyers lie, aren't you? It has enough. You made the claim that a diesel is much heavier than an outboard, and that simply isn't true. Further, the issue has nothing to do with the possible difference of 20 pounds, it has to do with the distribution. As to the relative weight, it seems that you want us to accept your personal opinions about how much the typical diesel engine for a small sailboat weighs from your single example, which omitted the necessary weight of the drive shaft, the mounting, etc.. From your note, it seems that you are saying that I should just shut up and accept your propaganda based on that example. - Perhaps it would clarify things if you provided some stats about the weight of several typical diesel installations on smaller boats. (Including ALL associated components, including drive shaft, cooling system, through-hull components, fuel and water filters, pumps, mounting structures, controls, fuel tanks, etc.) Remember also that the Mac, with its light weight and high freeboard, needs reserve power for control and to get through chop, adverse winds, etc. (And to avoid going through the usual discussion of why the Mac should have been designed differently to avoid such limitations in the first place, I acknowledge that the high freeboard is a disadvantage, but it's also an advantage in that the boat is roomy and comfortable and includes an unusually large cabin. - The light weight and lack of weighted keel are disadvantages, but they permit convenient tailoring, motoring or sailing in shallow waters, and high-speed motoring, etc.) As previously noted, my comments on this ng are intended to help provide a balanced representation of the Mac (missing in other discussions), not to claim it has no limitations.) And BTW, the diesel appropriate for a boat as light as yours would be a single cylinder, which would weigh just about the same as your outboard. Care to provide specs on a few examples, Jeff, along with their gross weight? And, as mentioned above, remember that the Mac, with its high freeboard and light weight, needs substantial power to get through chop and adverse wind conditions, to stay on course in extreme weather, and to dock efficiently. - A small diesel isn't going to cut it. Also, a small diesel isn't going to get the boat on a plane either. - No more quick runs back to the marina, no quick passages to desired skiing areas, no water tubing for the kids, etc.) Sounds like fun. Might I remind you that a few years ago you were insisting the Mac could do 18 knots while I was saying that was unrealistic, you probably wouldn't do much over 12. Here's the quote to which you apparently refer: No, that wasn't the specific quote, but it was one of several. Actually, I objected to the claim that the high speeds could be used when returning in bad weather. Given all of the warnings about running at high speed or without ballast in chop over one foot, this appears unrealistic, if not impossible. Incidentally, in notes on the MacGregor discussion groups, speeds of over 20 knots are being reported when sailing without the ballast, and with a larger motor. - I personally haven't wanted to motor without the ballast so far, but I'll give it a try this Spring. There is no doubt that it can be fast in flat water and unloaded. I was referring to comments of Mac owners about powering from California to Catalina and elsewhere with full loads at high speed, but without ballast. Flat water, Jeff? All the way to Catalina? Of course, put that engine on a proper powerboat and you'd do about 40 knots, so what's your point? Most owners of 26-foot cabin cruiser power boats seem to use two or three outboards substantially larger than mine, or large inboard-outboards. Don't think your plan (one 50 hp outboard) is going to work Jeff. I was still doing substantially more than any other sailboat on the Bay, and there were plenty out there. (And as mentioned above, I didn't have the throttle wide open.) yada yada yada And, despite the "yada yada yada", ..... doesn't that example indicate that the Mac has obvious advantages relative to its capabilities under power? I think most unbiased readers would acknowledge that fact. bragging that you can power faster than sailboats. impressive. You didn't quite get it, Jeff. I was responding to your remarks to the effect that the Macs can't power efficiently under severe weather conditions. (On this trip we had chop, white-caps, winds sufficient to convince skippers of several larger boats to sail with only a main or jib, and I was motoring under partial power.) You introduced the topic. You then tried to put me down, referring to (selected portions of) remarks of mine posted over a year ago, because I was "only" doing 13 knots. - I merely responded. Jim |

In general, it sails and powers well, it doesn't "pitch" excessively, and it is fun to sail. But not as much fun as a boat that sails better. What is pitching "excessively"? Enough to notice? Enough to cause ridicule by other sailors? If the boat's moment of inertia is too high, then the boat sails slowly and pitches more than it would if the weights were closer to the hull's center of volume. In other words, the hull, motor, and ballast, are inherently flawed in design to enable the big heavy motor. A compromise, not an efficient or effective design. JimC wrote: The 26M is the result of years of development, feedback, and mods. It does a lot of things most sailboats can't do.

It's relatively inexpensive, if you are willing to compare the costs of new boats to new boats, or used boats to used boats, and not compare the costs of 15 year old boats with that of a new Mac 26M similarly equipped. It's cheap compared to motorboats of similar cabin size. *That* is the key selling point, plus the bonus that trailerable motorboats of similar cabin room require a much heavier & more expensive towing vehicle. And, (I almost forgot) it's a lot of fun to sail. If you're not picky. DSK |

It clearly isn't what you meant the first few times around, but if you think it saves some face for you, so be it. or you just showing what type of lawyer you really are. Obviously the boat was designed to float on its lines with full ballast and an engine. The issue is whether a different distribution of mass would lead to a boat that sails better. And just how would you redistribute the mass, Jeff? - Where would you move the outboard, and where would you move the ballast? I would not have designed this boat at all, so don't asked me have I might change it. All I wanted to do when I started this topic of discussion was to rationally consider how the different weight distribution affects stability and balance. But you wanted to turn this into something quite different. The 26M is the result of years of development, feedback, and mods. It does a lot of things most sailboats can't do. If serves the needs of most sailors, under the conditions experienced 90% of the time. That's nonsense!!! It's relatively inexpensive, debatable if you are willing to compare the costs of new boats to new boats, or used boats to used boats, and not compare the costs of 15 year old boats with that of a new Mac 26M similarly equipped. So why do they seem to depreciate twice as fast as other boats? And, (I almost forgot) it's a lot of fun to sail. only for those with low standards. Maybe it would. But it's still a lot of fun to sail as it is. (I'm repeating myself, but isn't that the point, after all? Is it? Little children think picking their nose is fun, is that your standard? You fight every detail tooth and nail, even when you know you're wrong, and then you say "it doesn't matter that I'm lying because I'm having fun." Jeff, we may have differing opinions, and you seem to have confused your own opinions as facts, but would you please name the more egregious instances of my lying? Perhaps you could list the top ten instances? Being a clever lawyer, you word things so that they will be taken one way, but you can claim you said something different. Your comment above about balance was one such example. The "double liner" discussion is another. Your claim that the outboard is much lighter than a diesel is another. Your claim that the ballast is very close to the center is yet another. They question is, Jim, when have you been completely truthful? The boat is fast enough to be fun to sail, Jeff. It's not as fast as some other boats, but it's still fun to sail. - Isn't that the important factor.? (Actually, I wasn't having too much problem keeping up with some, though not all, of the larger boats on my last cruise.) All boats are fun to sail. That's not the point. You make lots of claims, and then try to write them off by saying, "but its fun to sail." What's your point? However, I don't think I agree that a typical diesel, with generator, fuel pump, filters, prop shaft, etc., would weigh about the same as a modern outboard. - Any stats on that one? I thought I just gave one. The weight of a 15 Hp Yanmar, including everything (alternator, pumps, filter) except the shaft and prop is 249 lbs.

As to the relative weight, it seems that you want us to accept your personal opinions about how much the typical diesel engine for a small sailboat weighs from your I was quoting from the Yanmar specs, using the most frequently spec'd diesel for small sailboats. Originally I mentioned to two cylinder version, because you had asked what someone had in their boat. But for one as light as the Mac, a one cylinder could do. single example, which omitted the necessary weight of the drive shaft, the mounting, etc.. I mentioned to driver shaft. However, the weight on that could vary a lot, and its so low it could be considered ballast. From your note, it seems that you are saying that I should just shut up and accept your propaganda based on that example. - Perhaps it would clarify things if you provided some stats about the weight of several typical diesel installations on smaller boats. (Including ALL associated components, including drive shaft, cooling system, through-hull components, fuel and water filters, pumps, mounting structures, controls, fuel tanks, etc.) More lies! I mentioned that the weight for a diesel doesn't include several items, including the drive shaft. It does include most of the others you've mentioned - fuel filter, cooling system, pumps, alternators etc. Some of what you claim are needed for your installation. Are you trying to claim there is no mounting hardware or reinforcement, no controls, no fuel tanks? How about the fact that the gas engine needs twice the fuel? And of course, the primary issue here is that the weight of the diesel is well forward, while the outboard is as far aft as possible. And BTW, the diesel appropriate for a boat as light as yours would be a single cylinder, which would weigh just about the same as your outboard. Care to provide specs on a few examples, Jeff, along with their gross weight? The Yanmar 1GM is 179 pounds with transmission. And, as mentioned above, remember that the Mac, with its high freeboard and light weight, needs substantial power to get through chop and adverse wind conditions, to stay on course in extreme weather, and to dock efficiently. - A small diesel isn't going to cut it.

You claimed your engine was much lighter than the diesel on most similarly sized sailboats. I pointed out you're wrong. |

Jeeze, Jim, do you really feel the need to fight tooth and nail on every issue, including those where you're completely wrong? Is this a lawyer thing - do you get paid the same even when your arguments are stupid? I sort of get paid for knowing what the hell I'm doing, Jeff. And I seldom loose. But winning in your business is not the same as being right. In my experience, lawyers are more often on the side of "wrong" than on the side of "right." (I think that's because the forces of "wrong" can afford more of them!) If there are lawyers representing both sides, how can more lawyers be on the "wrong" side? - Some of them must be on the "right" side. Regarding my particular specialty, I was an intellectual property and licensing attorney, not a trial lawyer. Our legal system has problems, and I'm not defending it, except to say that most cases are settled more or less equitably without going to trial. - It's the outrageous ones that get the publicity, not the other 95%. Sort of like the rest of the news - everyday hard work and ethical standards isn't newsworthy. And let me point out again, its not the weight, its the location. A 250 pound engine hanging off the stern contribute far more to the pitch moment than an inboard close to the center of the boat. Well, that's clear enough, and I agree.

The boat is built to be balanced, under sail or power, with the motor and a typical crew in the cockpit. It's built to sail and motor as efficiently as possible with the compromises inherent for it's intended use. In general, it's well balanced, it doesn't "pitch" excessively, and it is fun to sail. Either you're too stupid to follow the discussion, or you just showing what type of lawyer you really are. Obviously the boat was designed to float on its lines with full ballast and an engine. The issue is whether a different distribution of mass would lead to a boat that sails better. Maybe it would. But it's still a lot of fun to sail as it is. (I'm repeating myself, but isn't that the point, after all? The reason I bought the boat is to have fun sailing it, not to race it.) Also, I believe that the new 26M hull is more efficient for sailing, and smoother when plaining(though perhaps not quite as efficiently) as the older model. Actually, the motor isn't much more astern then the crew sitting in the cockpit, or the skipper sitting on the back seat over the transom. If a 4000 lb racing boat boat sailed with one large (250 lb) crew hanging off the stern, and another standing on the bow, it would be substantially slower than its competitors. (Not to mention being more uncomfortable.) So, what's your point. The 26M was built as a family cruiser, not a racer. Most racing boats in this size range wouldn't be as comfortable or as roomy or as versatile as the Mac. Plus, it's lots of fun to sail. However, I don't think I agree that a typical diesel, with generator, fuel pump, filters, prop shaft, etc., would weigh about the same as a modern outboard. - Any stats on that one?

Here's the quote to which you apparently refer: "JAX, did it ever occur to you that some owners of cruising sailboats may take them out to enjoy a pleasant day of cruising with friends or family from time to time rather than racing their boats? If I'm taking my family or grandkids out for a day on the water, there may actually be times when I sail the boat with everyone sitting in the rear and with less than optimum balance and sail trim. - Shame, shame on me! On other days I may want to take more care in adjusting the sails and balancing the distribution of weight in the boat to get as much speed as possible. (Like, planing the boat at around 12 knots under sail, or 18 knots under power.) The bottom line is that some of us sail for the pleasure of it, and some of us go sailing as a competitive sport, so that they will be able to brag about winning a race or sailing by several other boats. I enjoy both aspects, but I recognize that the Mac isn't a J-boat and isn't designed as a racer. So I don't expect to pass many large displacement boats" Incidentally, in notes on the MacGregor discussion groups, speeds of over 20 knots are being reported when sailing without the ballast, and with a larger motor. - I personally haven't wanted to motor without the ballast so far, but I'll give it a try this Spring. This particular day was fairly rough, and I wasn't running the motor full throttle. - I still think the boat would motor at 18 knots on a smooth day without the ballast. - But I haven't seen those speeds yet, because I've been reticent to motor without the ballast. Yes, buts that's been my point. If you want to keep the boat very light, and are willing to forgo ballast on a flat clam, you can achieve the high speeds. But you've just proven my old point that loaded up with a bit a gear, and dealing with a bit of weather, you won't want to go that fast. I was still doing substantially more than any other sailboat on the Bay, and there were plenty out there. (And as mentioned above, I didn't have the throttle wide open.) Very nice. Beautiful little girl, and dog also. I suppose you can anchor in fairly shallow water also. I'm in the same area as Joe, between Houston and Galveston (third largest number of pleasure boats in the US). I don't think our harbors and anchorages are as nice as yours, although we can get to the gulf in a few hours. I've only sailed on the FL side of the Gulf - I enjoyed it a lot, the Naples area has been on our short list of possible places to move to in a few years. Incidentally, does Durgins Park still serve Indian Pudding? Fresh baked. The best. Jim |
