Just like fuel and a motor is to a power boat sails eventually
disintegrate after prolonged exposure to UV rays. Therefore even with a crew
who didn't require food or water any sailboat would eventually loose her sails
and come to a stop.

How sad a post for Loco! Sailboats have unlimited range. A sailboat can carry
enough sails to sail around the world twice with ease.
Sorry, Loco. You just joined Thom is the loser circle.
But if you really want to be crazy, lets just say that eventually the
fiberglass will turn to dust or the sun will expand and dry out the oceans
or.....

Bwahahahahaha!
