This is simply going to fascinate you, yeah.
The physics, therefore the engineering, of a trimaran is so different to a monohull.
It is not right to think that a trimaran is just a monohull with training wheels – the whole needs to be designed in sync, as there are dynamic values, not least which is ft lbs on the amas [floats]. And these are completely different for a tri coming off a wave onto an ama’s bow to the mono absorbing all that in the forequarters near the bow.
That main hull factor still exists, given a certain angle to the waves but it is expressed as a percentage of the total load at any one time. In other words, the force on the boat, in foot lbs, is distributed and that can only be good.
It’s far more dynamic and difficult to calculate than for a mono or cat, hence amateurs don’t often design and build oceangoing tris.…
