Just ordered two packages of this for my damage control kit. It's
available from West Marine and Jamestown Distributors although JD
seems to have the better deal. The video is impressive.

I suppose if this is a low pressure leak it might get you home. Better
than an old rag and duct tape . ;-)

Absolutely, and a lot less collateral damage than running your boat up
on a sandbar or beach. I think it would be particularly useful on a
boat with exposed running gear where a strong prop hit can push the
shaft strut up through the hull. I've seen boats where that has
happened and even a 40 footer will start sinking *very* quickly.

I used to hang out with the DCs when I was bored on the ship and I sat
in on some damage control exercises. They make a whole lot more
substantial patches. Granted the depth of the hull might be more but
if you are trying to fix bow damage and you plan to get underway,
there will be a surprising amount of pressure on your patch.
If you just used this for the "gasket" and backed it up with some
shoring you might have something that would get you back from the
islands.
I agree having a couple cans of this on board is not a bad Idea. It
just might not be all you need. I wonder how long it lasts.

It's really not designed to get you back from the islands - more of a
first aid measure to stop the bleeding and buy you some time. Getting
underway at more than idle speed is probably not advised but if you
can stop or slow the ingress, you have a chance to catch up with your
pumps, get outside assistance and/or jerry rig something more
substantial. First priority is to keep the water out of the boat.
Once it hits the engines or batteries you're pretty well pooched.
