See............. cofferdam or cason

But why bother when ya can just yank the boat out with a sling
put on the beach at high tide.... wait for low tide
put lift bags on the stern bouy the aft end up
there are a few others but anint gonna give up all my secrects.

Duhh, put it on a trailer and take it home................

Check spelling
coffer dam or CASSION

I recently read of a Japanese or Chinese freighter with a holed hull
being fixed in Hawaii by use of a cofferdam. I think the article was in
Professional Mariner. Seems it was going to Cuba and was embargoed from
US ports. Took all kinds of diplomatic shenanigans to get her fixed.

Don't know of anything for a small boat.

Closest thing would be a "collision mat" but that would not allow you
the working space.

Given the buoyancy needed you might be better off to use wreckers floats
or "lift bags" to lift the boats stern.
