Fishing kayak

Abstract

A fishing kayak is described comprising a body having a bow end and a stern end the body comprising a deck and a hull. The deck defines a top side of the body of the fishing kayak and the hull defines a bottom side of the body of the fishing kayak. The hull comprises a pontoon hull portion extending from the stern end of the body along a longitudinal axis of the body, the pontoon hull portion being comprised of two pontoon members positioned in an opposing relationship, the pontoon hull portion defining a concave recess to form a tunnel structure. The hull also comprises a convex hull portion extending from the bow end of the body along the longitudinal axis, the convex hull portion being comprised of a convex hull member. The two pontoon members converge into the convex hull portion to form at least in part the convex hull member.
