Plans include: Full size drawings of paddle blades, thigh braces, seat templates and backrest template. Detailed building instructions and many illustrations. Also included is a list of material sources. Plus a background on the features and technique of the native Aleut style paddle.
Thigh braces are carved foam blocks glued under the front of the cockpit rim to form a comfortable contact point for your thighs to brace against during paddle strokes for a most efficient transfer of power. Thigh braces are also very important in outfitting a kayak to make Eskimo rolls easier.
One thigh brace block is visible in the picture below on the lower right edge of the cockpit rim.
This is the most comfortable seat you'll ever use. Carved from closed cell foam to fit you!
The contoured backrest is a curved wood strip panel covered with 3/4" thick close celled foam. A tongue of wood strip panel on the rear of the back rest fits into a slot in the foam seat to hold the backrest up. This allows clear space behind the backrest to stow gear. The backrest is adjusted forward and back via nylon straps at the sides.
The closed cell foam the seat is made from is extremely resilient and will never absorb water. It adds to the flotation of your boat. You can retrofit this seat into any kayak, glass, plastic, wood strip, stitch and glue, or skin on frame for paddling nirvana.
