I have a free hobie 18 foot cat without sails but with mast boom. The
Tramp would need to be replaced. The hulls are solid. I have been
trying to come with ideas with what to do with it.
I built a puddle duck racer and thought of making a trimaran using the
hobie cat hulls.
This looks like something fun to make at this link

Does anyone have any cool ideas to do with the hobie cat hulls?

That looks like the Kelsall Typhoon to me. It was based on
Tornado parts plus a new, third hull. I think Kelsall may
have designed something similar based on the H18.

Dick Newick did a lovely little trimaran based on the H16.

A friend of mine once built a 30' trimaran as a quick-and-
dirty project. The side hulls were lengthened A-cat hulls and
the middle hull was a scaled up Tornado hull with small
cabin. It was ugly and leaky but he cruised more with it
than I have done in my boat.

Somewhere on the Internet you may still find the Austrian guy
and his girlfriend who converted a Soling into a camper
trimaran.

So, in conclusion, you can have quite some fun creating
something new out of what you have plus some imagination
and time.
