    I am a new member and an amatuer inventor. I designed the beam/hull system to litteraly make the catamaran as strong as the best monohulls.

    It is a real public disclosure of my invention. I want ALL multihulls to freely use this design system. A structural engineer is recommended to complete concept versus reality stages of building.

    I have a lot of small boat ideas to try to develop a small homebuilder market.

    Sincerely DME

    There is a multihull forum here where you might make out better. I've been around multis for 40 years, but I am not sure I ever saw that. On the other hand, there is no problem making beams that will make a catamaran as strong as a mono. Structural failure is not the main problem.

    There are a few very successful designs that use metal tubing for the beams. For the most part, beams are made of either wood or synthetics. These are not difficult to massively connect, lightly, and without the need for metal working gear in the shop.
