Fusion Kit Catamarans
Boomerang is the one that we met in the bahamas. Check out that galley. very nice layout. Check out the double drawer stainless fridges and freezers. Much better than a C400.
I do agree that Lagoons, especially the 380, has small galleys. They have somewhat adressed that on the Lagoon 400.
Check out the Lagoon 400. LAGOON Catamaran - construction, vente et location - constructeur catamaran de luxe, bateau de plaisance et de croisère
The storage for clothes etc in the L400 owner's hull by far surpasses that of the aft statesroom in the C400.
And another benefit, your kids gets an entire port hull to themselves!
My C400 was relatively fast, in 15 kts she would easily do hull speed on a reach. I seem to remember to have seen above 9 kts on a broad reach in 25-30 kts of wind (need to get home on a sunday syndrome). Wild ride and it punctured my brand new dinghy as it was moving around in the davits.
She is an excellent power boat as well, would easily do 7.5 kts cruising at 2200 rpm, so the hull must be easily driven.
It's not that I need to go much faster than a C400's hull speed, it is that I would like a boat that sails very well in light winds because that's when I motored a lot (need to get to where I'm going syndrome...).
Given more time, I would have done what Jon suggested earlier, get a code 0 on a roller.
