Just before sunset, nine hundred nautical miles from shore, three sailors and a dog jump into in a four-person liferaft as waves crash around them. For four hours they bail water by the gallon, surrounded only by a vast and encroaching darkness.
By their nature, larger catamarans are exceptionally safe offshore. It is not unusual to sail through mildly uncomfortable conditions, such as a gale, only to arrive in port and hear sailors on keelboats talk of “surviving” horrendous weather. A large modern catamaran has plenty of buoyancy and exceptional roll inertia.
