LOL exactly!!

Well, not really

Everything on the boat needs to have multiple functions or there is no space. This includes emergency equipment.

A bit of extra fibreglass could be used for a multiple of ideas. including to splint a fracture.

But the comments here have been very instructive. A sheet of 3-ply, a few screws, a bit of rubber etc is a good solution to the blown hatch thoughts.



Alsways good to have ideas.

Further, they are very cheap, already on board, multiple uses etc.

Fibreglass too is very cheap and doesn't take much space at all.

I think it will be quite difficult to get any sealer or epoxy to stick well to the topsides or bottom and a piece of plywood without grinding off the wax or antifouling paint. Think more toward a cover with a gasket and sealer than a patch job if you are offshore.

I've read so many times that toilet bowl wax is a good emergency supply to keep on board. I carry two of them. Slather on a piece of plywood and screw it over the hole. I've never had to do it, but it sounds reasonable.

I have some. But this scenario is for a hole 1 or 2 feet wide x 1 foot long.

If it will adhere to a wet boat hull it should be good for your temp repair use with glass cloth/ply or most any thing

There are impressive tapes that would seal cloth, ply, most anything

A while back...
Overthehorizon posted about replacing bug screens with a poly or acrylic in their frames...when on passage.
To me, this makes good sense.

Mark,

Unsure if it answers all your questions, but few years back I read a short article on the subject in passagemaker dot com / channels / the ethos of damage control. Drill, screws, 1/4" plywood, 5200, putty epoxy, 100mph tape, felt or blanket, and expanding foam for support.

Quite correct, I missed the epoxy bit, cloth for epoxy.
