A patented hull design invented by Wesley himself, the Expandacraft hull parts are lightweight and easy to put together/take apart.
Expandacraft hulls were designed with a wave piercing bow which has several benefits. Tracking straight through a wave even at an angle is effortless and pitching motion is dampened. Drag in rough water is dramatically reduced compared to a typical kayak. A ridge along the bottom of Expandacraft hull parts also gives lateral resistance making them great for sailing upwind.
