Hull design refers to the shape and structure of a boat or ship's body, which is crucial for its performance in water. The hull affects how the vessel moves through waves, its stability, and its overall efficiency. Different types of hull designs, such as displacement hulls and planing hulls, serve various purposes, from fishing boats to luxury yachts. The materials used in hull construction, like fiberglass, aluminum, or wood, also play a significant role in durability and weight. Effective hull design considers factors like hydrodynamics, load capacity, and intended use, ensuring that the vessel meets safety and performance standards.
