What type of boat hull is often known for its air pocket that produces lift?

The tunnel hull is specifically designed with a unique shape that creates an air pocket beneath the boat as it moves through the water. This air pocket generates lift, allowing the boat to rise up on top of the water rather than plowing through it. This feature enables faster speeds and improved fuel efficiency, which makes tunnel hulls particularly popular for high-performance applications, such as racing or shallow-water navigation. The design helps reduce drag and enhance maneuverability, which is a significant advantage when operating in various water conditions.

Other hull types, while they have their own benefits, do not possess this unique air pocket lift mechanism. For instance, flat bottom hulls provide stability in calm waters but are less effective at higher speeds. Deep-vee hulls are designed for cutting through waves, enhancing performance in choppy conditions, but they do not produce the same lift as tunnel hulls. Cathedral hulls offer a wider base for stability, but they also lack the specialized lift produced by the tunnel design.
