=== 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 [https://en.wikipedia.org/wiki/Chine_(boating) chine]. Usually harder chines on ww kayaks, though it is easier to flip instantly. Can vary from 0 to 90 deg.

=== Rocker ===
