The width of the two cat hulls will be so wide that you don't even need beams to secure the two hulls to eachother. You can just lash them together. Another cost saver !
It will be like a heavier optimist (because it has decks) with a wall running through the middle of the hull.
Keep the good idea's flowing everybody !
