:: What is the "class shape"? Is this described anywhere?

:: Thx, M.

Every sailmaker has their unique class kite shape. Class shape are full girth specified by rule measurment and primarily shouldered runners. These sails are ideal for windward-leward courses. Some are relatively flat across their head gores being more all purpose for apparent angles to 130 degrees. Other are fuller shapes up high for 160 to 180 degress down wind. .7 nylonn airex for sale is the Quantum design evoled from Paxton protoype effort. All current Quantum sails I know of are this design.
