It can float smoothly on the water mainly because the materials used and the hull structure have four advantages.
1. Lightweight and strong: Fiberglass is a very lightweight material, much lighter than steel, and at the same time has high strength, good toughness and corrosion resistance. The lightweight of the ship can reduce the weight of the hull, reduce the probability of damage, and increase the load capacity.
2. Foam sealing material: The interior of the FRP hull is usually filled with thermoplastic materials, such as foam (PP/PE), etc., to increase the buoyancy of the hull, improve the sealing of the entire hull, and reduce the risk of water leakage.
3. Good streamlined shape: FRP material can be cut into various shapes according to design requirements. It is easier to shape and design than traditional hull materials. It conforms to streamlined design and reduces towing resistance and pressure loss.
4. Structures that can be welded: FRP structural parts can be connected through welding technology, showing high overall strength, certain wear resistance and impact resistance, and the mutual fixation of welding points is also Helps improve stability
