Must Skis new triple Dyna-Ski. Notice how high this heavy boat floats unlike the older style triple rigs. Boat Builder
Sure it's got plenty of ballast up front. Looks just as high in back as any Tom Miller boat to me. Bob
Identical hull shapes displace the same water, unless we checked nautical engineering fact at the door. There can be no difference, actually, unless the lower hull mold was changed in a way that would impact upon water displacement. I don't think there is any difference. Of course, I don't happen to agree that higher is better...but then I digress....
There you go.... A longer hull will displace more water. The longer boat also allows for greater leverage from the increased distance from the bow balast to the stern. This would allow the boat to handle weight better on the back, although ,as always, you get some disadvantages (alas, compromise) from making a boat bigger. If the eight inches is added at the stern, where the boat is wider, it would make a bigger difference in water displacement. If it is added at the bow, it won't make as much difference in balast but will improve the effectiveness of the balast. I can't tell if the 8 inches was added up front or in back.
Mark, If you look at the transom of a Dyne 20 you will see that the deck is longer than the hull centerline. The transom is not flat. The PJP boats have the aft part of the hull extended to be as long as the deck, or more. In short the length was added to the stern. The makes the hull centerline 20 ft or a little more, and the transom is flat. jim
Gotcha. That makes sense. I wonder if anyone has driven both boats who could opine on whether they handle differently.
Must-ski has already commented on that. I am sure he will do it again. I think he said each has it's advantages. jim
