Get a new bottom on then see if you can vacuum bag oil into everything else. you know, for science. this'll be a good one to watch
I've seen vacuum filling with small objects; but a whole boat? Have you ever done it or seen it done? Would need a powerful vacuum pump.
I was kind of joking. It would be pretty cool if you could squeeze oil into a boat though
might I suggest..... a new bottom using MDO. I've used it on my current powerboat build, and have fallen in love with this stuff. Do not confuse MDO with MDF....two totally different things. Medium Density Overlay. Tough stuff. Marine glues; plies laid up the same a marine plywood (which mdo is), and covered either one face paper or two faces paper. Paper is phenolic resin impregnated. Will withstand water/soaking without any treatment. But it's best if you epoxy/paint/or whatever coating(s) you desire, all faces and edges. The paper takes paint really nicely, giving an almost factory shiny look. Takes bumps pretty well, too. Saws/works really well. Comes in 3/8, 1/2, 5/8, 3/4, 1, 1 1/8. Glues extremely well. I used 2 layers of 3/8 on bottom of my 22 foot power boat. A little stiff, but she went on. Bronze screws all thru my boat, to avoid rust/corrosion. Great source for Pacific Northwest area builders is up in Woodland, Wa (find them on craigslist); as well as Eagle Plywood, in Harrisburg, Or (call them first and see if they'll help you....they were very willing to help me out). Other sources are in Lebanon, and Rickreall, Or. If you've never used MDO, I think you'll be impressed. I won't use any other material now to build a boat.
Thanks for your suggestion. I am familiar with MDO in another life as a wood products mill manager. I still like marine plywood. The bottom and sides are salvageable with a little trimming. New chines out of white ash I have done in my prior restoration. It's in the shop now fully drying out and getting rid of the accumulation of debris.
