The invention relates to a system and apparatus to improve performance characteristics of catamaran hulls. A catamaran hull comprises two sponsons, each sponson having an inner chine, and at least one chine extension attached to the inner chine of at least one sponson. The chine extension extends into a tunnel between the two sponsons and is angled downward from a horizontal plane. This system and apparatus provide a solution that generates lift by increasing the surface area of the chine and allows the catamaran to lean into turns rather than outward. Overall, it offers improved stability, reduced drag, and enhanced maneuverability for catamaran boats, particularly at higher speeds and during turning maneuvers.
