I prefer tri's for cruising. With any cat under 40 ft the room in the floats is not really much use and the bridgedeck is too low.
I have designed and built a 40 ft aluminium tri (look up beaus' boat on this multihull
Mine is a motor
sailor, with the sailing bit only with the wind
Designed for cruising and not racing
I believe a tri has more useable space, I have even gone double decker with mine.
I have outrigger floats that fold in like the Dragonfly so I can use Monohull
berths. I can also fit the boat inside a 40 ft shipping
container and ship it to cruising spots around the world.
I put two 30 hp honda
outboards on the back and I can cruise
at 8 knots with a top speed of 10 knots. However the fast displacement
design could easily take two 60 hp outboards. I am expecting to achieve 15 knots.
