A spinnaker is a sail designed specifically for sailing off the wind from a reaching course to a downwind, i.e. with the wind 90–180° off bow. The spinnaker fills with wind and balloons out in front of the boat when it is deployed, called flying. It is constructed of lightweight fabric, usually nylon, and is often brightly colored. It may be optimised for a particular range of wind angles, as either a reaching or a running spinnaker, by the shaping of the panels and seams.
A gennaker is a sail that was developed around 1990. Used when sailing downwind, it is a cross between a genoa and a spinnaker. It is not symmetric like a true spinnaker but is asymmetric like a genoa, but the gennaker is not attached to the forestay like a jib or genoa. The gennaker is rigged like a spinnaker but the tack is fastened to the hull or to a bowsprit. It has greater camber than a genoa. This is optimal for generating lift at larger angles of attack. An early form of gennaker was the "gollywhomper", used briefly in the 1870s.
The Spinnaker Tower is a 170 metres (560 ft) landmark observation tower in Portsmouth, England. It is the centrepiece of the redevelopment of Portsmouth Harbour, which was supported by a National Lottery grant. Its shape was chosen by Portsmouth residents from a selection. The tower, designed by local firm HGP Architects and engineering consultants Scott Wilson and built by Mowlem, reflects Portsmouth's maritime history through its being modelled and named after a spinnaker, a type of sail that balloons outward. The tower was opened on 18 October 2005.
In Search of the Most Amazing Thing is a video game designed by Tom Snyder Productions and published by Spinnaker Software in 1983. Although marketed as a children's game, it drew acclaim from players of all ages for its original concept and imaginative game world.
The Melges 24 is a one-design class of sailboat commonly used for racing. The monohull sportsboat is notable for its ability to plane over the water downwind in modest winds, and for its combination of a simple design that is highly tunable.
Spinnaker Software was a software company founded in 1982 known primarily for its line of non-curriculum based educational software, which was a major seller during the 1980s. It was founded by chairman Bill Bowman and president C. David Seuss.

An asymmetrical spinnaker is a sail used when sailing downwind. Also known as an "asym", "aspin", or "A-sail" it can be described as a cross between a genoa jib and a spinnaker. It is asymmetric like a genoa, but, the asymmetrical spinnaker is not attached to the forestay over the full length of its luff, being rigged like a spinnaker. The asymmetrical spinnaker has a larger camber than a genoa, making it optimal for generating lift at larger angles of attack, but the camber is significantly less than that of a spinnaker.
