Several pros and cons for flotation but if your gonna do it why not use polystyrene? It's much lighter and cheaper than the expanding polyurethane foams. You could fill most of the voids with polystyrene blocks then make up the rest of the volume with the expanding foam. Just a thought.
50lbs at the ends of an 18' boat will contribute to pitching motion.
