Muovirunko

Muovirunko refers to a plastic hull, a common construction material for various watercraft. This type of hull is typically made from fiberglass-reinforced plastic (GRP), also known as glass-reinforced plastic or simply fiberglass. The manufacturing process involves layering fiberglass matting or cloth with a polyester or epoxy resin. Once the resin cures, it forms a strong, rigid, and waterproof shell.

The popularity of muovirunko stems from several advantages. GRP is lightweight, which contributes to better fuel efficiency and maneuverability in boats. It is also highly resistant to corrosion and rot, unlike traditional wooden hulls, and requires less maintenance. Furthermore, the molding process allows for complex shapes and designs, enabling manufacturers to create efficient and aesthetically pleasing boat hulls.

However, muovirunko also has some drawbacks. While durable, it can be susceptible to damage from impacts, and repairs, though possible, can be labor-intensive. UV exposure over time can degrade the gelcoat, the outer protective layer, leading to fading and chalking if not properly maintained. The production of fiberglass boats also involves chemicals that can have environmental impacts if not handled responsibly. Despite these considerations, muovirunko remains a dominant material in the recreational boating industry due to its balance of cost, performance, and durability.
