Pigeons and Gudgeons has 245 pages with 135 photos and drawings. Two of the terms explained in Pigeons and Gudgeons are Sprit Rig and Spanish Windlass , both of which are illustrated with these photos. Other terms that appear in bold type are also defined in the book. The shape of the sail, you'll notice is like that of a gaff rig , but in this case the sail is peaked by means of the snotter attached to the lower end of her sprit. To the left are a pair of Spanish Windlasses being used to maintain the beam of a lapstrake canoe while she is being repaired .
Tension is applied by turning the levers inserted in the lines.
Bar or pipe clamps would be difficult to use in this instance because of the shape of the hull. The folded 2' rule is included for scale.
