A spinnaker is a large triangular headsail, secured only at the corners, used on sailboats when running down wind. Spinnakers are constructed of lightweight nylon fabric and are often brightly colored.  Many panels are assembled to create that deep sail shape characteristic of a spinnaker. They may be designed to perform best as either a reaching or a running spinnaker, by the shaping of the panels and seams. 

At MAD Sails we use Contender Superkote nylon sailcloth to construct our lightweight and durable spinnakers. The nylon sailcloth comes in a wide variety of colors to let you create the perfect spinnaker for your boat.
