Our Materials


Class 5 Boatworks LLC uses hulls made from thermoplastic sheets. Various thicknesses of plastic are used to provide not only strength and durability but also balance in the boat’s weight.

The sheets are cut and engraved with a CNC router. After all the parts are cut, certified plastic welders using extrusion welding equipment weld the various parts together into a hull.

Our welds are as thick or thicker than the plastic sheets themselves making the welded joints as strong as or stronger than the original material.

  • Resists denting (hit it with a sledge hammer and see!)
  • Self Healing (to some extent)
