Hull cross section

Round Hull: Easy maneuverability. V-shaped Hull: Potential for speed. Primary stability is less. Flat Hull: The most versatile. Common for ww kayaks. Tunnel Hull: Most stable.

Planing hull: Flat bottomed or sometimes V-bottomed and more rarely round-bilged. Displacement hull:

Chine

Hard or soft chine. Usually harder chines on ww kayaks, though it is easier to flip instantly. Can vary from 0 to 90 deg.

Rocker

Kayaks with high rocker are better for rough water, but they have less performance on flat water. Low rocker hulls goes on a straight line in the calm water.

Playboats, creek boats and river runners.
