The 8.9m catamaran is 1 m longer than the 7.9m catamaran. This difference in length directly affects the overall capacity and load-carrying capacity of the hull. Typically, a longer hull means a larger deck area and cabin space, so an 8.9m catamaran may have a higher load capacity and more spacious deck space. Although the catamaran itself has good stability, the increase in hull length may further improve the stability of the 8.9m catamaran. A longer hull may have a better distribution of buoyancy, making it more stable in wind and waves. At the same time, changes in hull length may also affect handling, but the specific impact must also consider other factors such as hull design and power system. In general, a longer hull may have higher speed and lower fuel consumption, but this also depends on the specific design of the hull and the configuration of the power system. In addition, hull length can affect wave resistance and maneuvering flexibility.
