Dan,

Sorry I haven't responded for a while. Been enjoying the nice weather in the south of France.
Looked at your latest *.dxf and that is what a planing hull should look like! For your troubles with the calculations, try different things! The program maybe made for single hull, but can give you an idea for catamaran. You have two pontoons, together 50 inch wide!

Thanks for getting back to me. I attached the "narrow" version here (see earlier post). It is also significantly longer.

I think I may need to flatten out the deadrise again on this one.
