Recently bought a used Laser on a Greek island. When it turned turtle on us we couldn't right it. How would injecting polyurethane foam in the mast end and possibly the gooseneck end of the boom work for keeping some water out as well as floatation, so the mast won't sink , work? I'd drill 1/4' holes in mast in a spiral pattern, inject the foam and after foam cures, epoxy the small drill holes. Anyone see any problems with that?
