What is the disadvantage of catamarans?

The disadvantage of catamarans on charter comes down to three things. First: in head seas, catamarans pound — the bridge deck slap is real, and some guests find it unsettling. A monohull cuts through the same water with a smoother motion. Second: most catamarans don’t sail close to the wind as well as a comparable monohull, so motoring is needed on tight passages. Third: dock space. Catamarans take up two slips’ worth of beam at marinas, which sometimes limits overnight options. None of this matters much in the BVI, where waters are protected, passages are short, and most overnights are on mooring balls. It’s why catamarans dominate the Caribbean charter fleet.
