Catamaran stability = beam and buoyancy and this translates into slamming and bridge deck clearance. Acceptable bridge deck clearance is 5% of
LOA, good clearance is 6% of
LOA. A good
offshore catamaran requires good buoyancy forward and a robust COG so that when it is going to
weather it is climbing the wave before the chest comes into play. The length of the bridge deck is important in that the convergence of the bow waves on the inside of the bows should be behind the aft is the bridge deck or you will have "drumming".
