Advanced hull shapes refer to the design of a boat's body that enhances its performance in water. These shapes are engineered to reduce drag, improve stability, and increase speed. Common examples include the catamaran hull, which features two parallel hulls for better balance, and the V-hull, designed for cutting through waves efficiently. These innovative designs often incorporate materials like fiberglass or carbon fiber, which contribute to lighter and stronger structures. Advanced hull shapes are crucial in various applications, from recreational yachts to competitive sailing vessels, as they significantly impact maneuverability and fuel efficiency.
