We've salvaged many different kinds and sizes of center console boats that were upside down when we arrived, most of them were full of foam and unsinkable almost all of these unsinkable boats will capsize when full of water i think this is a center of gravity issue not foam placement. But i could be wrong. The latest salvage i went on was a 26 searay pleasure boat i/o merc lost a inlet hose for the generator its also was upsidedown when we arrived.
