Asymmetrical Spinnakers (Gennakers)

The Asymmetrical Sail’s shape and radial construction make it ideal for running and broad reaching angles. With a triangular shape their cross-section design allows for a smooth, rounded entry tapering to a straight edge at the leech. Easy to handle, these spinnakers minimize a boat’s heeling angle when reaching.

Standard Size

Precision Sails’ Standard Sized Asymmetrical All Purpose Spinnaker is a good option for cruisers who need an asymmetric spinnaker for the widest possible range of uses. This versatile sail is ideal for anyone hoping to sail with only one spinnaker on board.

Its medium-full shape and full radial panel layout make it fitting for running and broad reaching angles. The spinnaker’s modern cross section design creates a forgiving shape with a smooth, rounded entry that straightens towards the leech. This makes it easy to trim and minimizes the boat’s heeling angle when reaching. The Asymmetrical Spinnaker is available in our High Tenacity Nylon and is designed for apparent wind angles of 80-155 degrees.
