Flotation 

          Never skimp on extra floatation in your hull. Some of the things used to help keep you hull floating if it rolls over and starts to fill with water are styrofoam, shipping air bags & swimming pool noodles. I don't suggest the foam in a can, because it expands and can cause damage to the hull. Also I like things that can the removed and dried out.

Don't loose that expensive, hard to replace hatch!

          Tape styrofoam to the underneath of the hatch cover, when it gets torn off in an accident it wont sink!
