SPY-10 Folding Sailrig (TDY, Oct 2002)

This sailrig is designed for use with FAP-16. It can be adapted to other folding kayaks with minor modifications. The amas are constructed using aluminum tubing, HDPE Cross sections, and a nylon/neoprene skin.

This ama design is based on, but not a copy of, the Chesapeake Light Craft Eight Footers that appear in Woodenboats #131, July/August, 1996. The CLC amas are made of plywood and feature a "V" shape cross section. The SPY-10 folding ama utilizes aluminum tubing with a nylon/neoprene skin. The cross sections are "Hard-Chine". The amas are 10 feet long to approximate other designs currently in use.

With 3 cross section and 3/4"X.035 tubing, the amas weigh 7lbs. each. Estimated weight with Nylon/Neoprene skin is approx. 10lbs. each. The 120lb. displacement figure is at point of submersion. The twin 10 foot akas are made of 1.5"X.049 tubing and break down into three sections. The center section is 4 feet, and the outer sections are 3 feet each. There are two 27" inserts per aka, which are made of 1-3/8"X.058 tubing. The akas are spaced six feet apart as Tom felt that was a minimum distance for paddle clearance.

Tom's workshop is pushed nearly to it's limit when the sailrig is assembled.
