This design is an 18′ one-sheet canoe called “The Dug”.
The prospect of building a one-sheet kayak, as presented in the original Prism section, has aroused some interest. This design is an attempt to overcome the balancing difficulties inherent in the original “maximum volume” design.
The design has been modified, using the righting moment calculator (free excel calculator) as an aid, to give an acceptable compromise between stability, volume, and looks.
