With a U-shaped & thinned-down bow section the hull works at its best when being driven hard. Inverted bow maximize the length of the waterline and hence the hull speed, reduce the size of the bow wave and has a better overall hydrodynamic drag.
It has solid longitudinal stability for rapid acceleration and minimum pitching movements. The kayak stays level in the water so is able to pick up maximum speed quickly, cleanly and efficiently.
Sharp cut away deck allows for close paddle entries and catches in both bow and stern positions.
Constructions differ in the materials and technologies used during the manufacturing process. These determine the stiffness and the interior appearance of the boat. In practice, an upper construction results a stiffer & more eye-catching boat.
Besides, the standard and available fittings may be also different in some constructions. These are listed at the "Fittings" section of this article.
