Beneteau's premium line??? What are you talking about, I wonder? . . . I was refering to the custom series, . . . semi-custom...they are very capable blue water boats. Beneteau will work closely with a buyer on these and heft mods can be had. www.beneteauusa.com/custom/57_photos.php And not only that, they (or, at least, the one sold so far in the U.S.) have the ability to "disappear" from the dock, too!! www.noonsite.com/Members/doina/R2004-01-20-1 charleston.net/stories/011704/loc_17sailboat.shtml beaufortgazette.com/state_news/regional/story/3232497p-2891624c.html www.coastnews.net/missingboat.html |

Graduates of the JAXAshby Advanced School of Scientific Sounding Sailboat Gibberish. Is there a correspondence course? Do they offer any electives in diesel mechanics? I doubt I could get in...I struggle with math. JAXAshby wrote Bob Perry would say different, but then Bob has publicly called me an asshole, but Bob has also publicly stated that he has struggled with math all his life, a statement on his part that I do not doubt. Actually, I don't doubt either statement Actually, I suspect that this is no more true than any other of Jax's claims, such as having sex with various well known actresses or sailing around the Atlantic looking for the Gulf Stream for a week. I am fairly certain that Bob called Jax an asshole in the old Cruising World forum. Then again, I suspect that it wasn't the first or last time Jax has been "misidentified" as an asshole, so I am not certain what that has to do with the boat, or the designer in question ..... Are you suggesting that yacht design is ultimately a mathmatical exercise and the best slide rule operator will design the best boat? That would be an interesting theory to test. It's already been tested. Ever since the origin of geometry, people have tried to use math to design better (usually meaning faster) boats. While the use of large computers has advanced the practice quite a bit lately, it seems that there is more to it than pure abstract number crunching. As proven by a certain groups highly advanced number crunched design that also crunched spars..... I think Bob's success speaks for itself. The boat has been a success, commercially and out on the water for over 30 years and is in the Sailboat Hall of Fame. If "scientifically trained sailors" wish to nitpick, then so be it. If memory serves correctly a few years ago there was an article in Good Old Boat magazine on factors affecting hull speed. The canoe stern doesn't allow as clean a separation of the stern wave in addition to a slightly shorter effective waterline at hull speed, both of which add a little drag. In another article the designer of the Valiant acknowledged the design limitations of the canoe stern but it was a requirement of the customer and that he worked very hard to minimize them. But above all, remember ALL boats are a compromise. JJ My only nitpick would be that the canoe stern reduces reserve bouyancy, and makes it awkward to mount hardware back there. Some people seem to think that the Valiant is similar in more than superficial aesthetics to some kind of historic pilot cutter or rescue vessel from the days of sail, but it is really a modern (1970s era) design. In it's day it was not a crab-crusher, rather it was on the light end of the displacement/length scale. Fresh Breezes- Doug King Well, I agree it is an "old" design. I have asked the Valiant folks if they have considered that a newer design might be about due, but they seem to feel that "if it aint broke, why fix it." Hard to argue with, I suppose. While I have never been aboard a Passport, I suspect that it might be a design that would have more appeal to me, particularly the stern, as you mention. A large part of why I admire the Valiants, though, is knowing the people who build them and seeing the way they are put together. They are very well made, and that is something that is every bit as important as the design. James Johnson remove the "dot" from after sail in email address to reply |

One benefit of the canoe stern that I don't think anybody has mentioned yet is that it is structurally stronger (all else being equal) than a transom. FB Doug King |

dougie, a "benefit" is something that adds to the overall effect. In this case
there is no benefit because there is no problem with transoms not being strong enough on the size and type sailboats under discussion. Calling it a benefit doesn't make it one. Don't you sell concrete slabs to trailor home people? You should know the difference between a feature, an advantage and a benefit.

Let's see... an inherently stronger structure is not better than an inherently weaker one? What sort of engineering is this? Oh wait, it's JAXINEERING! .... Don't you sell concrete slabs to trailor home people? No. Why, do you need to buy a concrete slab for your trailer home? Dsk |

so, making a transom (that doesn't break) 10 times stronger is a *benefit*?
Sounds like a disadvantage to me. Extra cost, extra weight, slower boat speed, all to fix a problem that doesn't exist.

That must explain why there's no such thing as hull speed... structural strength can be zero because they never break... that means boats can be weightless! Getting all this MC? DSK |

Oh that's a real benefit. I guess Doug must be saying that yachts often sink from their transomes falling off. Hahahhahahahaha. Cheers |

A reverse transom is still lighter and faster than a canoe and is designed to be strong enough. Your argument is ridiculous. Cheers |

Yes I'm seeing your ass get whipped again on very basic concepts. Why not throw in the towel? Cheers |
