New to Tri-marines

Hey all
well the IOM sailor has decided to give it a go. I was going to go about and design a foiler( I saw a few videos of the guy in Germany) but i decided that build a multi hull from plans first. get the problems out of the way first. then go play. I looked around and could not find a 3d printed tri. BUT i did find Nightmare off rcsailing. I have not gotten the plans yet. but when i do. I wonder what i should be looking for. I dont have a sail pattern yet. ( hoping the plans give me a set of numbers anyway.) If Dick is around maybe he can give me a clue as to what is needed.

wish me luck
