| If you just look at the TransPac website it's clear as day that 3rd place goes to Coruba a Nelson Marek 68. The owner's are Rob and Suzanne Fleming. Why do you post lies and then claim innocence when you know you are wrong to start with? |

note smiley. all you are looking for in crew is a bag of mostly water to compensate for the disign flaw of the vessel. Hear my note here. It is becoming the rally cry of US Sailing. Lets chat seriously about converting the TP52s to IRC racers after next year when their IRC ratings will be adjusted. James Boyd in his April 2005 Sailing World article (page 45) notes that the Vende Globe machines with canting keels also have water ballast. The question as to which is the primary ballast system on boats that have both may have been answered in that article. Vincent Riou, who is kind of a McGyver (technically proficient) when it comes to fixing things, was unable to fix hydraulic rams used to cant PRB's keel. This forced him to drop the keel down to leeward before any maneuver in the Southern Ocean passage of the 2004/2005 Vende Globe race, slowing things down considerably. However Boyd paints the failure of one of six centerline water ballast tanks on the same boat as more dramatic. The tank could not be repaired allowing air to enter it in a way that meant that 1.5 tons of water ballast could not be used effectively when PRB was on port tack. Boyd says there was an "explosion" involving the tank. So both ballast systems had failures. We come to see from Boyd's article that water ballast is the primary movable ballast form 50 miles from the finish line when the newly-launched-for-the-race Ecover's canting keel falls off. Rather than abandoning the race. Golding, fills the water tanks, extends the twin outboard dagger boards and twin rudders and then further stabilizes the boat by reducing sail. In this Mac26x configuration, Ecover sails at 9 knot speeds to become the first monohull in recent history to ever have finished a major race without the benefit of an external keel foil. The experience of PRB and Encover should be conclusive regarding which form of movable ballast is best. However debate will continue because of vested interests in canting technology and bulb keels. The best countering argument involves the fact that Riou had the benefit of high speed Internet access where as the other sailors were not able to keep their computer and wireless equipment operating at that speed. Fast web surfing for weather and sea information, in combination with a center foil that could gybe to windward (like the Mac26x) meant Riou could find better wind and sea conditions, point high to get to them, and make a better course to the finish line to win. This argument ignores the fact that Riou had moved ballast off of the canting keel of PRB by using a significantly smaller bulb and thiner foil so that he could add an additional internal (though possibly flawed) water ballast tank. TP52 owners could do the same. Pascal Conq and Guillaume Verder further explained PRBs tanks in an article in the July 2005 Seahorse magazine (page 45). PRB has water ballast tanks remarkably similar to Mac26x vessels. The designers call these tanks inertia ballast tanks and they are placed to make the center of gravity align with the center of buoyancy at a 10 degree angle of heel. Additional tanks along the centerline running bow to stern are being contemplated. The inertia ballast tanks provide substantial extra righting moment. "The distribution of these low centre of gravity ballast tanks is chosen to offer both increased inertia to go through waves in the upwind conditon and to counteract the pitching moment induced by the sail driving force in the reaching condition. This set-up was first trialled on Christophe Auguin's successful Finot 60 Geodis some 10 years ago." Christophe Auguin sailed Geodis to victory in both the 1994-95 Around Alone and 1996-97 Vendee Globe. PRB continues to demonstrate the winning ways of this design.

| Going back a couple of pages to the whole "planing wake" shot, let me post, for the benfit of those who have never seen it, what the transom looks like when you are planing. This is from a 40-footer at about 17 knots. Steve |

Frank, thanks for responding. So, it appears to me that the case of the children's deaths, operator of the 26X got underway without the water ballast the boat rolled over and the kids died. At least that is what I think happened. If I'm wrong, please say so and clarify for me. It would seem to me that if this is the case, the builder would have a lock out, tag out system that would prevent this type of manouver. You don't have to be drunk to forget something important. Then, I get confused when I also read in your additional posts that the 26X instructions say you can operate with or without the water ballast. At least that is what I thought you said. Please help me out if I'm wrong. I am also wondering if you could tell me what the limits of stability of the 26X is when it is unballasted and when it is ballasted. Back to the TP52, I see that you don't like the boats because they take a lot of crew, are big, are on the low end of positive stability and you don't like they keel. Does that about sum it up? Also, you don't like Tripp Gal because she doesn't like your boat and didn't give you the rating you thought you should have. Do I have that right? I look forward to your response so that I can understand this thread. |

[quote] Frankie also likes to omit the fact that the boat was grossly overloaded with something like 11 persons on board, plus a dog.The collective IQ of the adults on board was somewhere around 73. Edit: Make that two dogs, eight adults, and three children. Far over it's capacity, with or without the ballast tank filled. |

| "operator of the 26X got underway without the water ballast the boat rolled over and the kids died." And there is ONE of many problems with water-ballast...

| Frank did you know that the reason genoas, or any overlapping jibs arent used on boats today is because they are inefficient in anything over 8 knots? That is why there are code 0 sails. The only reason you get better upwind performance by easing your main is because your heading straight into the wind with the 50 HP down and running. |

I have to give Mr Ed shining marks today for posting this So we hear that resident Latitude 38 writer Rob Moore is leaving the mag after too many years. Rob turned in fairly pedestrian reports, and while there was not much to complain about his work, his love affair with a very few sailors bordered on ridiculous. That we dared to critique his boyfriends from time to time turned ol' Rob against us pretty quickly, and here is an e-mail that he sent out back in 2001: Scot Tempesta is a bitter person who is burning a lot of bridges in San Diego with his personal attacks on people (Leweck, Isler, Conner and many others) and things (PHRF, etc.). It isn't journalism, and no one in the industry expects it to last much longer. Scot has an occasional decent 'innerview', but most of it sounds like the rantings of a deranged and mostly ignored wierdo screaming at people from the street corner, shaking his fist at the world. That's just my opinion, of course. Cheers, R. Well guess what Rob - we're still here! And yes, I've taken a few good whacks at some of your idols, hell I even did just that yesterday, but who would have thought that you'd be dragging your sorry ass off to obscurity, and I would be commanding the most visited sailing site in the world? I think that is either great irony or poetic justice, either of which works for me. Scot and I share our concern for 38 north. In my case the article regarding the Mac26x had been about the only reason. See http://www.latitude38.com/features/ensenada.htm. I mean you finish first and it is a negative. Such spins. Scot clearly has many more reasons to be upset with 38 North than I. I point out that 38 North is now free at west marine. It use to be a buck here in the Pacific Northwest. So I suppose the price is right and it is time to check it out again. How many more articles from Sudie can any reader of 48 north take Seriously though, she claims to be an engineer. What rational reader would expect anything but dry prose from that back ground. Lets say she writes well for an engineer but her bias for the big boats and against IRC disqualifies her. |
