Abstract

A keel system for an inflatable kayak which is a one-piece plate of plastic material defining a pressure plate at an upper end, a skeg at a lower end and an attachment portion therebetween. The attachment portion includes upper and lower engaging elements to cooperate with the web and a grommet of a typical inflatable kayak to lock the structure at the stern. A similar device with a keel strip extending rearwardly under the hull is provided at the bow of the kayak. A rudder may be pivotally mounted to the aft edge of a skeg and stern post portion and in turn receive an outboard motor. Locking plate may be extended perpendicularly across the tops of the pressure plates to cooperate with the gunwales and spray cover of the kayak.
