Anybody can get a sail up; it takes a sailor to get it down. This statement is particularly true regarding the spinnaker. Hoisting the sail is not a problem. Getting it back on the boat is. That's how the ATN Spinnaker Sleeve makes the average sailboat owner a great sailor. Douse your spinnaker without drama: Without any help, the ATN Spinnaker Sleeve makes this very powerful and expensive sail disappear with a minimum of fuss and trauma. And the sail is ready to be hoisted again immediately, with no more repacking needed. Proven in the world's toughest offshore shorthanded racing: ATN Spinnaker Sleeves have been widely used in the Vendee Globe, Singlehanded Transpac and other solo and doublehanded races. Know your hoist measurement: To order an ATN Spinnaker Sleeve, you will need to know how high the sail can be hoisted (known as the "I" measurement). Your Spinnaker Sleeve will be made to the right measurement for your boat. For more information on how to order, contact West Marine Rigging.
