Re: Which emergency use fibreglass matting should I have?

In those conditions, it doesn't seem likely that you would be able to make a suitable patch with mat/roving and resin.

For an emergency in which a hatch or portlight has been broken, I'd want something like self-adhesive Typar flashing or self-adhesive ice and water roof underlayment. That stuff is tough, it sticks to anything, and it would make a good, water-tight gasket. Put it over the broken port. Have two pre-cut pieces of plywood that are slightly larger than the hatch's frame, one for the inside and one on the outside. Thread a bolt through a small hole drilled in the centers of the plywood pieces. Tighten up with a wing nut. Use a little butyl tape and an extra nut between the inner plywood and the flashing to keep the bolt from leaking. Once you have the situation stabilized, you can then think about sealing things better with more butyl tape, underwater epoxy, or resin & mat.
