My questions....if ya look in the middle...the planning hull.....as you start to move threw the water don't you think the air will get trapped under neath and help break the water friction? I know ..... the comments "oh that is too heavy, a Motorboat planning hull will never work....its just too heavy" I am sitting at about 175 pound right now. so its a lot lighter then I was expecting.

I guess it is possible for air to get trapped, but by making that 'W' shape you have increased surface area and weight. Yes, This half hull is heavy at 175lbs. looks like you still need a deck, a place to sit, mast step.. You are doing a trimaran correct? so you need structure for the beams to mount., etc. So with everything, I'd expect that weight to at least double. As long as you have enough power, weight alone is not a show stopper. You will need a fairly large rig/kite and/or a lot of wind. If you are going to use a kite-surfing kite as a sail, keep in mind those are designed to move a person and not much more (~200lbs). Your total weight will be triple that.
A foiling Moth weighs about 80lbs complete with rigging, foils, everything.

And also marine engineer,****ing idiots go in school,study 4-5 year, gain some experience about 10 year and maybe have the capacity in a group make all calculation to come on America's Cup, Volvo etc,

Have you picked a name yet for this project?

You could do something like what Eric Dahlkamp has done, converting a planing hull dinghy into a trimaran.....definitely worth a look...

I love my home built 16 ft trimaran, thin plywood and beach cat hulls I got for a song, and an 18 ft catamaran mast. It flew with 5 people on board, with just me it was wild.
Guess the designer?

I regret selling it but I had built too many sailboats and the wife put her foot down. It was a bit faster then the pacific proa,but many times I felt I was going to cart wheel
