The CAT 40 is a comfortable cruising catamaran using the latest thoughts on wide bodied hulls enabling much more accommodation than usual on a catamaran of this length. The standard arrangement has 8 dedicated berths (including 3 doubles) with the ability to sleep many more. There are 2 wc's and a large galley and deck saloon along with plenty of deep stowage space, a large cockpit and inside and outside steering positions. Construction is based upon pre-shaped ply bulkheads and frames being slotted onto the ply hogs/stems so preforming the shape of the hulls accurately without the need for lofting. Obviously on such a capacious boat, there is much scope for alteration both in layout and in the basic use of the boat. She could for instance, be used purely as a motor yacht providing a very stable platform for diving etc.
