Flotation placement is a bit of a conundrum. The best way to keep a holed boat upright is to put the flotation up as high as possible so it can't turn turtle in a wavy sea - BUT - flotation doesn't help a bit until it's underwater. Like GA, I also added styrofoam in the walls below the side trays and both ahead and behind them, but that's a limited space. I also put it under the gunwales and under the stern deck as well as in the nose. Apart from loss of lives, I figure my worst case scenario is watching the boat disappear into the depths with me responsible to raise it again for environmental reasons. - GrandadI have got a little done,floor cut and painted , bought my pink Styrofoam boards to replace old flotation foam.I guess I will
put it everywhere I can,I only want to keep the power head ABOVE water should the worse happen.
