Before sailing any Corsair trimaran, it's important that the safety compartment be loaded with the appropriate safety gear. This compartment is accessible from top or bottom and is usually located in a cockpit coaming or under the cockpit seat. Its purpose is to keep important safety equipment that should be available to the crew in any emergency situation, including a capsize. The equipment stored here should include flares, a handheld VHF radio, EPIRB (offshore), extra line, spare tools, cutting implement etc. and all in watertight bags (this is not a watertight compartment). No multihull should venture offshore without safety gear in such a compartment.
