@maritimemaster: One boat leans in every gust, the other sails flat, and the flat one is the one that cannot right herself after a capsize. A catamaran gets a big righting lever from width alone, but it usually runs out before she is on her side, while a ballasted keelboat still has hers with the mast in the water. So reef a cat by the wind speed and never wait for the lean. #catamaran #sailing #sailboat #seamanship #maritimeindustry
