Well, basically, if the line should come off the cleat, then the sail will
unfurl and flog itself to death.

I generally cleat off both sheets fairly tight. Then as Roger says, if I'm
expecting a storm or will be gone for a long time I'll add a separate tie
around the sail.

I add the sail tie whenever I "stop" anywhere. That way, it's part of
the routine, and I don't forget it. That also means I don't forget to
untie it before taking off, which could be a real inconvenience at
times, especially when single-handing.
