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 comes in a wide variety of colors to let you create the perfect spinnaker for your boat.

** Please note fluorescent colors are more sensitive to UV and not colorfast and therefore not recommended for offshore and transoceanic sailing. Always make sure your spinnaker is completely dry before folding and storing it to help keep colors from bleeding.
