What materials are used to make jet skis?

Jet skis are primarily made from materials such as fiberglass, reinforced plastic, and high-density polyethylene (HDPE) for their hulls, which provide durability and resistance to water. The interior components often include aluminum and stainless steel for structural support and corrosion resistance. Additionally, jet skis may have foam or rubber materials for insulation and cushioning, and various plastics for smaller components and controls.
