One of the regulars on an email list I belong to just posted this:

************************************************** ********
The local coast guard came down to a boat which had hit a rock with a
can of foam-in-place. If you can slow the leak down somehow you can
fire that into the bilge or wherever and it will hold the water back
long enough for you to get somewhere. It is tenaciously gooey. I'm
planning on putting a can onboard.

Interesting...

If you read the about the exploration trips of the 1500's to 1800's one
of the techniques to save the ship was to rig a canvas patch over the
hole. The technique was used when a ship hit the rocks or when a cannon
ball holed the ship below the water line.

The foam sounds like a good substitute for canvas, and would probable
provide a better seal. Wish I had thought of it and I hope I will never
have to use it.
