A guy in town has some 18 foot catamaran hulls that are in really good shape, and they are about 28 inches tall - he only wants $150 for the pair. I was wondering if I could use these as a basis to build a cat power boat? You know, take the hulls, space them about 7 feet apart and build a deck on top of it. Power could be twin 15hp outboards? I bet it would work, what do you think?

I think its a great project, and not too time intensive. Keep it simple and get out on the water.

Hi there, converted hobie cat hulls to a powered vessel using 4 hulls and glass over ply deck. The hobie cat 14 hulls are not great for carrying any weight so I joined two each side and glassed a flat bottom internally just below the waterline. She cuts through the waves with ease and I am getting 18 knots out of a 9.9 horse johnny! Very stable and allows me to go 24 kms offshore to my fishing ground and return in any weather. as per pics, the pics show the early days of the build before reassembly with glass, the seats swivel to allow for travelling and fishing and access to the bait sink in the centre which is also great for the berly which drains out through the waste and under the boat.
