Anybody used this seabung thingie yet? May beat a diver under the boat with a plunger (been there). http://www.seabung.com/index.html
I've always carried a bag of various wooden bungs, never failed yet. Big hole in the side of the hull? Deflate the rubber dinghy and strap it over the gap. Not pretty but it works.
It looks like it would work, however the sealing section seems to be pretty pliable. I have not seen them in person yet.
A customer pointed this thingie out to me and ask what I thought. I hate to offer single opinions on something not in my hand. Wood pencils, plugs, plungers & up to #4 PFDs have been in my hands and have worked for me. I'll let this thread run a few days more and then get this customer to enroll and check this thread out.
