You should really spend some time learning about your boat, Jim. I never questioned whether there was a substantial amount forward of the mast. Nevertheless, since the hull, and the tank, narrows toward the bow, and since the lever arm extending from the mast to the bow is relatively short, water ballast at the bow would have little effect on the distribution of mass. Jeff, did you happen to take courses in geometry and logic in high school or junior high? The reason I ask is that you obviously know nothing about either subject. Actually, I majored in Naval Architecture for two years before switching to Physics. Then I worked for NASA for 6 years. Any more questions? Yes, several. - If you majored in physics and Naval Architecture, why do you seem to know so little about them. And, what did you do for NASA. - Surely you weren't designing any boats for them, I hope. (Incidentally, I worked for NASA for 11 years, and was recently asked to do more work for them.) - The fact that the water ballast tank in the Mac extends toward the bow, forward of the mast, is not determinative of whether it extends about 2/3rd the length of the boat. It starts at the bow, and it ends at the stern. The diagram clearly shows the water ballast running the entire length of the boat. If anything, it looks that the tanks is deepest in the forward area. The cross-section at the forward station under the hatch appears to be by far the largest, indicting that a large portion of the water ballast is forward. Here's the diagram again: http://www.macgregor26.com/drawings/drawings.htm please tell us if there's any other way to interpret this? The issue, of course, is whether the mass is substantially centered or whether substantial mass exists at the bow and stern, which might affect the distribution of mass throughout the length of the boat. Since that's the substantive issue, why don't we concentrate on that one. And with a 250 pound engine hanging of the stern, that's a lot of mass in the extremities. Nope. The hull is built to handle the weight of the motor. As well as the weight of several adults in the cockpit. (Remember that my statement was in response to Scotty's ridiculous remark that the water ballast extends "all the way from stem to stern." - Why didn't you criticize Scotty for making such a stupid remark?) Because I made it. And is what is your problem with it? Are you claiming that the diagram on the Mac site is faulty, that the tank does not run the entire length? Or are you arguing on the meaning of "stem to stern"? As stated, the drawings clearly show that the ballast tank has narrowed toward the stern such that there is an insignificant volume of ballast water (and mass) toward the stern. Instead, by far the greatest volume (and mass) is in the area near the mast. Thus, the water ballast tank, with greatest mass located near the center of the boat, would help rather than augment any pitching moment. Also, the ballast tank is tapered at the front and back such that the volume (and mass) of water held at the front and rear portions is substantially less then that held toward amidships. Clearly, there seems to be little ballast in the stern, but with the heavy engine, plus the possibility of a full cockpit, its probably not possible. However, the largest cross-section of the tank is shown at the station halfway between the keel and the bow at the waterline. While the bow obviously "tapers in" (yes indeed, they did make the bow at the pointy end) which means the ballast must be reduced in the forward few feet, but so is the buoyancy. Additionally, the heavier, permanent ballast is positioned amidships, below the mast. Just where ballast should be. Good for them. Jeff, I've sailed many boats. The Mac 26M doesn't pitch excessively and doesn't pitch more than most others. (Have you sailed the 26M? - No?) I'd love to, but most of the Mac owners hardly ever go out. I have sailed by them a number of times and they do seem to bob around more than heavier boats. Perhaps you need to have your eyes examined. Jim |

Thus, the water ballast tank, with greatest mass located near the center of the boat, would help rather than augment any pitching moment. Yes, there is less ballast aft, but it is certainly not "insignificant." You have a way twisting the truth around. You're saying, "Yes, I lied about the ballast but it doesn't really matter." And, as I said, with that large engine hanging off the stern there's a huge amount of weight back there. In fact, with a 50Hp engine running well over 200 pounds, or perhaps 8% of the displacement, that's like a 30 foot cruising boat carrying a 800 pound dinghy in davits. Now try telling us that has no affect on the pitch moment of inertia. Wrong again. it extends about 2/3rds, and the front and rear portions of the tank taper to sharp end portions and are therefore of little mass and no real consequence re the distribution of mass. Not according to the published diagram: http://www.macgregor26.com/drawings/drawings.htm Its pretty clear from this that the ballast extends all the way forward, and that in fact a substantial amount is forward of the mast. You should really spend some time learning about your boat, Jim. I never questioned whether there was a substantial amount forward of the mast. Nevertheless, since the hull, and the tank, narrows toward the bow, Actually, it doesn't look like it narrows that quickly. In fact there looks like there's a lot more water ballast at station 1 than anywhere else. Since you keep denying the truth, we'll just keep posting the diagram so that everyone can appreciate your sense of reality: http://www.macgregor26.com/drawings/drawings.htm and since the lever arm extending from the mast to the bow is relatively short, Gee, isn't the lever arm forward of the center of mass roughly half the length? Actually, we want to use the center of buoyancy, which is well aft, thus increasing the lever arm. water ballast at the bow would have little effect on the distribution of mass. This is total nonsense. Most designers make an effort to keep the fuel and water tanks as close as possible to the center of the boat. My large water tank, for example is athartships at the center. Look at any large Hatteras and many other powerboats and you'll find the fuel tank is at the center. You've been making a big deal about the water ballast, but now you're claiming its not in the stern, its not in the middle (because that's where the fixed ballast is), and the amount forward would have "little effect." What are you Jim, some sort of lawyer? Jeff, did you happen to take courses in geometry and logic in high school or junior high? The reason I ask is that you obviously know nothing about either subject. Actually, I majored in Naval Architecture for two years before switching to Physics. Then I worked for NASA for 6 years. Any more questions? Yes, several. - If you majored in physics and Naval Architecture, why do you seem to know so little about them. Right Jim. You sound like a total idiot saying one thing when the drawing of your boat clearly shows you're lying. And, what did you do for NASA. - I was the senior programmer for the data analysis for the Einstein X-ray Observatory. Everything from telemetry to navigation to image processing. Surely you weren't designing any boats for them, No, but I did work for a year for a successful America's Cup defender. However, my work was almost entirely in sail research. Does that count? I hope. (Incidentally, I worked for NASA for 11 years, and was recently asked to do more work for them.) So how much engineering did you do? - The fact that the water ballast tank in the Mac extends toward the bow, forward of the mast, is not determinative of whether it extends about 2/3rd the length of the boat. It starts at the bow, and it ends at the stern. The diagram clearly shows the water ballast running the entire length of the boat. If anything, it looks that the tanks is deepest in the forward area. The cross-section at the forward station under the hatch appears to be by far the largest, indicting that a large portion of the water ballast is forward. Here's the diagram again: http://www.macgregor26.com/drawings/drawings.htm please tell us if there's any other way to interpret this? The issue, of course, is whether the mass is substantially centered or whether substantial mass exists at the bow and stern, which might affect the distribution of mass throughout the length of the boat. Since that's the substantive issue, why don't we concentrate on that one. OK. The boat weighs 3700 lbs with 1150 lbs, or 31%, of that water ballast. Now you just claimed that at sections 4 and 5 the water ballast is "insignificant." And the diagram clearly shows that much of the ballast tank at section 2 and 3 is actually occupied by the fixed ballast. So in fact, a large portion of that 1150 pounds of water is well forward. And while the boat obviously narrows at the bow, since the ballast tank doesn't extend the entire width, there is actually very little narrowing of the tank until you get to the last two feet. And, since there isn't much of a bow overhang, its pretty clear the there is a lot of mass well forward when the tank is full. And with a 250 pound engine hanging of the stern, that's a lot of mass in the extremities. Nope. The hull is built to handle the weight of the motor. As well as the weight of several adults in the cockpit. Again, you sound like an idiot here, Jim. You should quit trying to sound like an engineer. There was no claim that the stern was going to fall off. The point is that boats are usually designed to minimize mass in the extremities, and thus reduce the pitch moment of inertia. By comparison, on my boat, which weighs triple yours, I use the lightest possible ground tackle to save a hundred pounds or so from the bows. There is no excess mass at all in the forward ten feet of the boat. As stated, the drawings clearly show that the ballast tank has narrowed toward the stern such that there is an insignificant volume of ballast water (and mass) toward the stern. Instead, by far the greatest volume (and mass) is in the area near the mast. No, the drawing clearly shows that there is even more water forward of the mast. Have you even looked at the drawing? By claiming there's little water ballast aft you're claiming there's even more forward of the mast! Thus, the water ballast tank, with greatest mass located near the center of the boat, would help rather than augment any pitching moment. Sorry Jim, anyone can clearly see that you're lying. Let's have another look at that drawing: http://www.macgregor26.com/drawings/drawings.htm Yup, it still shows the largest cross section of water ballast at section 1, well forward of the the mast. Sorry, Jim. The Republican approach of repeating the lie over and over until someone thinks it must be true has been discredited. Perhaps you can get someone else here to explain it to you. |

The Mac 26M has a a drainage opening and large gate valve positioned on the lower portion of its transom, the purpose of which is to permit the ballast water to drain out of the tank when desired. The narrow, elongated, cross-hatched "bulges" shown at the bottom of the hull in cross-sections 4 and 5 are actually channels that conduct ballast water from the ballast tank to the drainage opening when the bow is elevated.

And, because of their small volume, they have little effect on the distribution of mass along the longitudinal axis of the boat.

Seems to me that this is just one more example of the fact that the most opinionated, inflexible critics of the Mac 26m are those who have never sailed one. From everything you've posted Jim, there's no evidence you've ever been on one either. Well, have a nice evening anyway Jeff. Happy sailing. Jim |

Or that your statement, copied below, was wrong? "And the other issue is that the water ballast extends all the way from stem to stern. This can't be helping the pitching moment at all." You really don't get it. First of all, the tank truly does extend all the way from the stem to the stern. If all they wanted was a conduit, they could have put in a tube with a lot less expense. You're only claiming that the volume aft is relatively small. But that just means the the volume forward of the mast is that much higher. This supports my claim that there is a lot of mass in the extremities. Go back to my comments, this is about mass in the extremities which increase the moment of inertia. And of course, your claim that the ballast tank is only a "conduit" rather blows away your "double hull" assertion. And by the way, what happened to your claim that the entire boat was protected by a "doubled hull" - now you're claiming it's just a small portion. Was that just "lawyer talk" that we can ignore? Give us a break Jeff. - Where did I say that the "entire boat" was protected by a doubled hull? A large portion of the lower portion of the hull is, indeed, "doubled," but the two-layer "doubled" portion doesn't extend beyond the ballast tank. In all prior discussions of the matter, I have certainly attempted to make that point clear. But the problem is that when the boat is at high speed it will be planing with the bow raised up. Thus the vulnerable portion is the aft part that you're claiming now is not double hulled. In other words, although you have repeatedly claimed this as a significant advantage, its value is really limited. In fact, even the Mac marketing literature doesn't mention this; why do you think this is? Is this something you made up, or just something a salesman told a gullible customer? BTW, if the hull was compromised and you brought it up on a plane, the tank could possibly drain, leaving you in the dangerous situation of having several hundred pounds of water surging around. Jeff, you criticise me for making ad hominem attacks, etc. Actually, my friends and colleagues consider me a courteous, laid-back, amicable kind of guy willing to listen patiently to all sides of a discussion. I'm sure you're one helluva guy. Did I ever mention that my closest sailing buddy had, as his first boat, a Venture 22? (Its a period he doesn't like to talk about!) - I would be happy to minimize the ad hominems and to treat you and other Mac-Bashers with all the respect and deference you deserve, I really don't know why you consider me a "mac basher," all I've tried to do is honestly consider the attributes of the boat. In fact, my involvement in this thread only started with a consideration of how water ballast affects stability. You've tried to make it sound like all proper boats (you said "most ocean-going vessels") use internal ballast, but in fact most designers would consider it a choice of last resort. Of course, for a trailerable boat it makes sense, but a lot of Macs I see are kept in slips, which certainly minimizes that. and I'll do so just as soon as I see some of the same from you and the other Mac-Bashers. Meanwhile, I suppose that I'll continue to give as well as I get. I wouldn't get too excited about how much you've "given." |

I sailed a water-ballasted boat for years and was quite happy with it. I didn't try to claim that it was wonderful & perfect & faster than everything else. Did your's have a weighted keel? Yes, but just barely enough that it would sink when you released the pennant. The centerboard did not form any meaningful percentage of the ballast. FWIW that boat (1994 model Hunter 19) sailed rings around the Mac 26X in all conditions.... we did so many times while sailing in company with the ones in our sailing club. And I have a great deal of confidence it would also sail rings around the new -M model. It was a practical and fun little boat. Fresh Breezes- Doug King |

Google proves MacGregor 26 is flimsy
Jeff, I have had other matters to take care of the past several days
(including cooking Thanksgiving dinner for family and guests, and also taking the boat out), and I have been somewhat derelict in not responding to some comments in your more recent notes. - Jeff wrote: I actually did engineering, what did you do? Write product liability waivers? You have trouble taking the high road here, Jim, after you explained to us that all of the warnings that come with a Mac is just lawyer talk that can be ignored. Unless, of course, it can be used to save the company when children die as the boat rolls over in calm weather. It really amazes me how you can shift positions to suit your need. Is that what you learn in lawyer school? Sure thing Jeff. - Of course, it's clear that you cherry-picked and substantially misrepresented what I said. I never said that the warnings that come with a Mac can be ignored, and you know it. In fact, in the very discussion from which you quote, I made that point quite clear. What I said was that, IMHO, attorneys were involved in the wording and display of the warning, and that in later sections of the owners' manual instructions are given for motoring WITHOUT the water ballast! (Incidentally, Jeff, do you actually think that attorneys were NOT involved in this matter?) As far as my own interpretation and practice, I have never sailed or motored my Mac 26M without the ballast, though I would not be adverse to motoring WOB in relatively calm conditions. I note that many other Mac owners routinely motor the boat without the ballast. Also, remember that the 26M includes substantial permenant ballast that remains without the water ballast. Once more, Jeff, where did I say that those warnings could be ignored? Or were you confusing your own particular interpretation of supposed implications with what I actually said? Also, why would you stoop to cherry-pick that one statement, when you know full well that my further statements during that particular discussion made it quite clear that I certainly did not think the warnings should be ignored? It starts at the bow, and it ends at the stern. The diagram clearly shows the water ballast running the entire length of the boat. If anything, it looks that the tanks is deepest in the forward area. The cross-section at the forward station under the hatch appears to be by far the largest, indicting that a large portion of the water ballast is forward. Here's the diagram again: http://www.macgregor26.com/drawings/drawings.htm please tell us if there's any other way to interpret this? Yes, there is another way to interpret it. - The correct way. The Mac 26M has a a drainage opening and large gate valve positioned on the lower portion of its transom, the purpose of which is to permit the ballast water to drain out of the tank when desired. The narrow, elongated, cross-hatched "bulges" shown at the bottom of the hull in cross-sections 4 and 5 are actually channels that conduct ballast water from the ballast tank to the drainage opening when the bow is elevated. When the gate valve on the stern is opened with the boat sitting on a launch ramp, for example, water from the ballast tank is permitted to drain out through the drainage valve, a process that takes about 4 minutes. - In other words, the cross-hatched portions you interpreted as being part of the ballast tank are actually conduits that communicate with the ballast tank for permitting the ballast water to drain out, but they are not part of the tank itself. And, because of their small volume, they have little effect on the distribution of mass along the longitudinal axis of the boat. OK, you made your point, there's not much ballast aft of the mast. Of course, my point has really been that there's a lot forward of the mast, so you just helped prove my point. I think it's pretty clear by now that you lost on that point, Jeff. The sections you thought were extensions of the ballast tank were drainage tubes for permitting the tank to drain out the valve on the stern when parked on the launch ramp. More significantly, your original theory was that, because the ballast extended "the entire length of the boat," you thought it would contribute to pitching of the boat. As should now be understood, the volume and mass of the ballast is in an area slightly forward of amidships, rather near the mast. Moreover, the ballast tank is tapered at its forward and rear end portions, further reducing the mass of ballast spaced furthest from the central or largest portion, thereby lessening the moment of inertia of the ballast when the boat pitches upon a wave, etc. As to the fact that the ballast tank extends forward to the bow, two factors apply. First, the distance from the longitudinal center (largest or widest portion) of the ballast tank to the bow is substantially shorter then that to the stern, so it's appropriate that the ballast tank extend to the bow (remembering also that the forward portion or the tank is tapered, thereby reducing pitching inertia). Secondly, for balancing the boat in the water to compensate for the weight of crew and motor at the stern, it would again be appropriate to position the longitudinal center of mass of the ballast tank somewhat forward along the length of the hull. And by the way, what happened to your claim that the entire boat was protected by a "doubled hull" - now you're claiming it's just a small portion. Was that just "lawyer talk" that we can ignore? And with a 250 pound engine hanging of the stern, that's a lot of mass in the extremities. Nope. The boat is designed to be balanced fore and aft with an outboard and several persons in the cockpit. Jeff, you again misquote what I said to make your point. - I never said that the "entire boat" was protected by a doubled hull. Only that adjacent the ballast tank. - Do you have any ethics at all? You also again cherry picked the statement you relied on, since in later portions of that discussion some months ago I made it quite clear that the boat didn't have a doubled hull protecting the entire boat. - But you knew that when you decided to misrepresent and cherry pick my statement, didn't you Jeff? You shamelessly misquote and cherry-pick when you think you can get by with it. - Do you have no self-respect whatsoever, Jeff? In other words, you are totally ignorant of the concept of "moment of inertia." Perhaps you should take some time off now and review basic physics. This is the central issue of the discussion, and now you're confessing that you have no idea what its about. Good one, Jim. ... Additionally, the heavier, permanent ballast is positioned amidships, below the mast. Just where ballast should be. Good for them. As noted above, the boat is designed to be balanced with an outboard and with several persons in the cockpit. And it is. Yes, the large mass in the stern (the engine) is nicely balanced by the large mass of the water ballast in the bow. Now explain to us the meaning and significance of "moment of inertia." Moment of inertia in this context relates to rotational inertia, that is, the tendency of the boat during pitching movement to keep rotating, or pitching, in the same rotational direction. The moment of intertia of a body with respect to any axis is the sum of the products obtained by multiplying each elementary mass by the square of its distance from the axis. Since it's proportional to the square of the distance from the axis of pitching rotation, MacGregor's design (positioning most of the mass near amidships rather than evenly distributed along the entire length of the boat) was proper. Incidentally, Jeff, there are other forms of inertia (e.g., resistance to upward and downward movement, resistance to deceleration of the boat during forward movement) that are in some respects disadvantages to small, light boats such as the Mac. As I have consistently stated, the Mac has good and bad features, and one of the disadvantages to any light boat is that it doesn't sail as steadily, with as much forward momentum, as does a large, heavy vessel. (You would have done better to ignore the ballast issue altogether and concentrated instead on some of the obvious disadvantages of small, light boats.) Jeff, I've sailed many boats. The Mac 26M doesn't pitch excessively and doesn't pitch more than most others. (Have you sailed the 26M? - No?) I'd love to, but most of the Mac owners hardly ever go out. Really? And do you have any evidence to back up that bit of propaganda? In any event, I was out sailing my Mac yesterday. - When was the last time you took your boat out Jeff? I have sailed by them a number of times and they do seem to bob around more than heavier boats. Actually, it's probably true that the Macs, weighing only around 4,000 pounds with ballast and crew, "bob" around more than a 20,000 lb vessel. Then again, its also true that a Ferrari or Porsche weighs less than and has a stiffer ride than a Lincoln Town Car. It sort of relates to personal taste, and what you're going to do with the vehicle or vessel. For example, I motored back to the marina at around 13 knots, despite rather choppy water conditions, which gave me more time out on the Bay for sailing. And, when did you last have your eyes examined, Jeff? Funny thing, as I've grown older my vision has improved. Now I spend most of the time without wearing the glasses I've worn since I was ten. I guess that means I've just gotten smarter. Interesting. I also stopped wearing glasses several years ago. - Does that mean I'm getting smarter too? Jim |

Jim I was just joking around Jim. The thread has gone on way longer tha I expected and broken up into so many different discussions...I was trying to be silly. |

The boat is built to be balanced in the water with crew and with an outboard of 50 - 70 hp. If the moter were removed, the boat would tend to "lean" forwardly, with the stern too high in the water. The weight of the outboard is far less than the weight of a typical diesel in a 27-29 Not really.

The chief disadvantage of the larger engine is that it gives Mac-bashers who have never sailed a 26M another opportunity to turn their noses up at Mac owners. Although the Macs don't point as well as conventional boats with weighted keels, I doubt seriously that the weight of the motor is a major factor. Rather, it's the compromises relating to the internal ballast, trailerable hull, and lack of weighted keel. (The metactric effect.) Actually, the engine by itself doesn't bother me that much. I think that if you asked detractors if they would accept an engine with 3 time the power if there was no cost in weight, fuel usage, initial or maintenance costs, etc., most would take it. The problem is that most hulls are designed for sailing, not powering at high speed. The Mac made a number of compromises - a flat "powerboat" hull, no external ballast, that greatly diminish its sailing ability. 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. The more important factor, however, is that they are lots of fun to sail. So you say. Why is it that you almost never post a trip report? |

Nothing to do with sailing? Sure it does, Capt. - If you can't get out to the sailing area with time for sailing, and return in time to get guests home in time to get to the opera or theater (or wherever), you can't go sailing as often. The whole boat is a compromise that anyone with any sense of what sailing is all about would only accept in a very, very narrow set of circumstances. Yes, the boat entails compromises, but it's still a lot of fun to sail. Actually, if we are honest, all boats are compromises Capt. - For example, the 40-ft Valiant I liked so much entailed a number of "compromises." For example, it couldn't motor faster than 7-9 knots, if that, so getting it out from the marina to where we sail, and getting it back, took quite a long time. - You would have to consider carefully whether you had the time to get it out and back and cleaned up before deciding to go out on an afternoon. Also, the draft was so deep that, at low tide, I couldn't make it through the channel leading to a preferred anchorage in the Galveston area. Further, because of its weight and size, it usually required at least one additional crewman when maneuvering into and away from a dock. Additionally, the costs of upkeep, bottom treatment, slip rental, etc., were substantial. - In contrast, I don't suffer from those "compromises" with my Mac. - I can get out to sailing areas at speeds of 13-14 knots, and similarly return to the dock after sailing, even in rather breezy weather, so I'm able to get out and sail even when I can only spare a few hours. Regarding the "compromise" of not being able to navigate channels at low tide, on the Mac I can easily raise the dagger board somewhat and motor through waters of two - three feet. (A big advantage when the local marina has no more transient slips available.) Moreover, the boat is small enough for easy single-handed sailing and docking, in contrast with the larger and heavier boat, which is "compromised" in that it usually requires putting together a crew before going out. (In my case, I can go out with or without a crew.) The Valiant was a great sailing vessel and could reach nine knots in a good wind, but it took a rather long time to get there. - In contrast, I feel the acceleration and the effects of the wind more quickly and more directly in the Mac (making it more like a sports car rather than a Lincoln Town Car or Suburban, etc.). - Sort of a personal preference thing, of course. As to the "compromise" of high expenses for maintenance, slip fees, etc., I pay $70 per month to keep my boat in a lot. Launching involves merely hooking up to the trailer and towing it 100 yards to the ramp. No bottom treatments are necessary, no wear and tear in a slip, no continued salt water exposure, and I don't have to run down to the boat to move it or chain it down when we get storm warnings. Again, the "compromises" experienced with a larger conventional vessel are largely avoided. Capt., I had my 26M out Saturday, sailing in 15-kt winds. Some of the heavier, conventional boats (with twice the water line) were faster and probably pointed higher, but I still had a great day of sailing. - Which is what I bought the boat for in the first place.

Jim, you can rant all you want, but yours is the a very restrictive
application for a compromised vessel. It's not a great sailing vessel; it's not a great power boat. In fact, it kinda sucks at both. All your efforts at supporting your boat must take away from your sail time. -- "j" ganz @@ www.sailnow.com "JimC" wrote in message om... Capt.

Neither would I. I just don't want one on a 26'er.
