Rotational Molding Watercraft
“ Watercraft is a boat, vessel, or craft designed to move across or through water. The name is derived from the term "craft" which was used to describe all types of water going vessels. The term craft has since been expanded to include all types of vessels which travel on water (watercraft), in air (aircraft) and in space (spacecraft).”
“Most watercraft would be described as either a ship or a boat. However, there are a number of craft which many people would consider neither a ship nor a boat, such as: canoes, kayaks, rafts, barges, catamarans, hydrofoils, windsurfers, surfboards (when used as a paddle board), jet skis, underwater robots, seaplanes, and torpedoes.”
