What is jetski made of?

Jet skis are primarily made of fiberglass or plastic materials, which provide a lightweight and durable structure. The hull is often constructed from high-density polyethylene (HDPE) or fiberglass-reinforced composites for strength and resistance to corrosion. Internal components, such as the engine and mechanical parts, are typically made from metals such as aluminum and stainless steel. Some high-performance models may also incorporate carbon fiber for added strength and reduced weight.
