How many ping pong balls does it take to float a sunken boat?
I think I remember seeing that on mythbusters once
Personally I don't own a boat to me they are nothing more than a temporary hole in the water that you pour money into.
Yes some perhaps many salvaging operations can be as simple as pulling a boat to the surface by allowing it to create its own lift due to hull design and forward movement,
The making of the ping pong balls just reminded me of the show I once saw where they tried several times to raise a sunken boat before they were successful.
Not all boats can be raised by the cable and tow method small pleasure craft or bass boats and jon boats sure but a cabin cruiser or just about any sail boat and all larger craft would require a tremendously powerful tug capable of attaining a good amount of headway. Even on small craft the sea cocks would have to be open and the boat would have to be towed sufficiently long enough for enough water to be evacuated before it could gain sufficient buoyancy to remain afloat long enough to be boarded and have the hull sealed. Temporary patches to a damaged hull if this was the reason for it sinking might be possible to install while the boat were on the bottom. If it were swamped due to a storm then it could be resting upright on its side or completely turreted. Or if it were resting near a drop off shelf or in a boulder strewn bottom there may not be enough area to pull it far enough for it to begin planing, that is why far more require the brute force of a barge crane or buoyancy bags even those fail sometimes if water cannot be displaced from within the cavities of the boat.
Maybe one might want to pump beach balls or inflate huge balloon type bags into the cavities then finish off with ever smaller balls until finally using ping pong balls to achieve at least neutral buoyancy.
I think his max was about 40' boats. I saw that show too, long ago.most use air bladders now days. FYI boats are not just a hole in the water to pour money into.some are land yachts that never leave the trailer....I made a good living working on boats.mostly go fast boats, cigg,fountain, douglass skater,apatche and a few not so go fast too. when your on the other end of the hole it aint bad!!!ESPECIALY WHEN IT'S A 3/4 MILLION PLAY TOY..
"" land yachts that never leave the trailer""
yep my younger sister's ex husband put them in debt to the tune of $90k for a bass boat he just had to have then she and he had to work overtime 2 jobs and weekends to stave off the repo man for many years by the time he could actually afford to get back into bass fishing he thought he had to have a new boat .
I'll give you one guess why he is an ex.
