Sink the boat and climb the mast. It is important to stay with the boat!

You're about 300 feet offshore, so it's too far to swim. You've got
Bob****'s boat and he was too cheap to put in gas, so you run out.
There's a slight breeze pushing you away from shore. You don't dare
take off the mainsail cover because the mainsail has long ago
disintergrated from lack of use, and you don't dare unfurl the jib for
the same reason.

The last time you checked the flares, they had expired in June 1981,
and were thrown out. You've got no oars or paddles, and the radio
doesn't work.

What do you do?
