Abstract
Abstract A sit-on-top kayak having a seating and footwell arrangement that allows three people to sit comfortably in a cockpit of the kayak. Three seating surfaces and footwells are preferably employed. The footwells associated with the two rearmost seating surfaces straddle the two forwardmost seating surfaces. An improved hull is provided having a keel and winglets extending on either side of the keel. The keel and winglets terminate at the front in a bow portion of the hull lower surface and come together at a point at the stern of the kayak.
