[quote=Edchris177]Other options that come to mind. Back in WWII, the US air force sank some planes in a river in China. The locals swam out & inserted a bunch of bamboo into the fuselage til it floated, very low tech, but effective.
I'm not fmiliar with the hatches on the Dart, but if they are problematic, you could get a couple of webbing straps under the hull,(using a sawing motion), then tie a coupe of inner tubes to the webbing & inflate with a compressor. Once the hull comes off the bottom it is very easy to place a truck tube under the hull & inflate. Any tire shop should have a "pig", a 5 gal canister that holds compressed air to fill tires. You can recharge it on shore via an electric compressor, then wade out & fill tubes.
I moved an elderly neighbors SeaDoo lift to his dock by tying several 5 gal plastic containers to the frame,(upside down) then blowing air into the open bung to displace the water.
You will be surprised how much a single car inner tube will float. You entire boat is only 300lb. Less mast, rudders etc, probably 200, & you still have one hull floating. It won't take much to get the other one floating to where you can hand pump it out.[/quote]
