I agree that traditionally wetting out glass, doesn't strike me as a viable emergency procedure. It was one of the scenes in Robert Redford's, All is Lost, that I found silly (many others too, including how the hole was made in the first place).

However, epoxy made for underwater use is a different story. It's thick (some even as thick as putty) and typically mixes 1:1, so measuring isn't that hard. I've not needed it for survival, but have for other purposes. Perhaps the bigger problem, especially in bad conditions, is that it could find itself adhered to everything within striking distance, including the crew. Very, very sticky. A box of nitrile gloves is a good idea aboard, for all sorts of reasons.

it's hard enough to work with epoxy on a calm day and a level surface. Use the stuff Minni recommends. have storm covers for the ports in the hull and plywood and the right range of screws and washers to make emergency repairs.

pay attention... someone's life depends on it

Very nifty trick!

I will keep that idea in the shaddows of my mind.

Re: Which emergency use fibreglass matting should I have?

Good ideas. I was thinking about how to seal the repair of a plywood hatch cover. Still consider using toilet bowl wax to stuff in the "lip" of the gap between plywood and deck. Think: deck, rubber matting, plywood with the wax to fill any cracks. Or use pieces of cloth to fill any gaps. Then I thought (the reason for this post) ... I wonder if you could use expanding foam (like from an aroseol can you buy at a hardware store). Would it become waterproof? Would it set in a moist environment? It would be interesting to experiment with it, to see if it works.
