Awwwww, no EPIRB?
Every single-handed sailor seeking solitude, and an ultimate test of himself against the elements using only skill, wit, intellect, and maturity will of course take along a device to summon help when things get too scary.
I think they call this the 'run home to mama'.
If you go in the drink out there, or you're attacked by a grizzly out there, or a really harsh cold front blows through, or you snap a leg in a slip and fall, or you run out of food or water, then you're dead--EPIRB or no EPIRB.
I'm surprised to read replies from self-professed 'pro' and 'knowledgeable' sailors who suggest a beacon would have helped the protagonist. An EPIRB would help 'rescuers' rescue the body. That's why no EPIRB.
