Monohull sailors have for years argued that multihulls are not nearly as safe. I heartily disagree. One of the primary laws of physics is that “Everything in nature seeks its most stable position.” The most stable position for a catamaran is indeed upside down on the top of the ocean. But the most stable position for a monohull is at the bottom of the ocean. A well built and properly designed catamaran is very hard to sink – you must either be run over by a tanker or suffer a massive fire.
