Hi folks, first post from a lurker. I've been looking for damage control solutions beyond the standard peg/wedge/hammer, particularly for folks who may not have had formal training and could use all the help they can to give the bilge
pumps a fighting chance.
I'm envisioning a flat sack made of a strong rough fabric
material that is filled with hydrogel beads, which in their dry form resembles pebbles. You'll be able to roughly jam it in the breach, and as the gel absorbs water
and expands it'll maintain a strong wedge on both sides of the hull
. The beads are shelf stable if the sack is sealed in a pouch to be opened for user?
