Asymmetrical Spinnakers and Gennakers

Asymmetrical spinnaker, also known as a Gennaker, offers a shape and radial construction that 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.

Asymmetric spinnakers operate more like a jib, generating lift from the side, rather than the top like a symmetric spinnaker. Precision Sails offers 7 size options for our Asymmetrical sails; each spinnaker is custom designed from scratch and reviewed before production to maximize performance and handling. When it comes to customizing your asymmetrical spinnaker the options are endless! [


Predesigned Asymmetrical Spinnaker Sail

Our Standard Sized Asymmetrical All Purpose Spinnaker is a discounted option for cruisers needing a versatile sail.

It’s ideal for those who sail with just one spinnaker, suitable for running and broad-reaching angles. The sail’s modern design allows for easy trimming and reduces heeling when reaching. The spinnaker’s modern cross-section design creates a forgiving shape with a smooth, rounded entry that straightens towards the leech. Made of High Tenacity Nylon, it works for apparent wind angles of 80-155 degrees. This also allows for the sail to be used without a spinnaker pole.

Pre-designed options include solid colors and a red, white, and blue pattern.
