[quote=charlescarlis]Welding the hulls depends entirely upon the type of plastic used in the roto-molding process. Martin is correct, at least for Hobie's plastic concoction; don't know about anyone else. There's a whole science to that business and the stuff that is thermoplastic/weldable isn't near as stiff as the stuff Hobie and others use - so they don't use it as much.[/quote]
