Night Heron Double Sea Kayak
Night Heron Double Sea Kayak
Allen Newhouse Night Heron Double

Drawing inspiration from my Night Heron design to create a tandem kayak, this boat has the swept up ends and overhangs characteristic of that design along with the raked cockpit that makes entry easier.

Although the plans for this design are currently available, I have not built a prototype and am reluctant to fully vouch for the performance so I consider it still on the drawing board.
