This thread has gone completely to the technical or should I say mathematical side of the equation, instead of the basic question of should he build it or not. I say build it. As to the earlier statement that A's are out because of their 7'6" BEAM. That is not applicable here, for you would be using other beams. I know of a few sets of A class hulls that could be had for this project. All of them need some work, but that is about it. I also possess two T-Hulls that could be had for the right price.
What I like about tri's beyond their inherent stability is the fact that they point higher than most cats do. I built my trimaran "Skyhook V" with my partner Ken King, formerly of Navtec and launched 1994. 39’10”LOL and 28’4” on the beam. Built of western red cedar with e-glass skins and carbon fiber at the main stress points. The design was one that we began and Chris White finalized. This is a 20 design of his to look at for ideas.

Build it and goes have some fun.
