We just received this picture from North Idaho College. This is one of the small G-Spinns built in a Bi-Radial design. It shows how the sail is being used to make sailing easier. It is made with 1.54 oz. nylon, has a spinnaker sock to make it easier to use. This is the sailing instructor for North Idaho College.
New G-Spinn with vertical battens, reaching and pointing in light air.
