Sew it yourself! Spinnaker Sock Kit 42'1" to 45' lets you make your own spinnaker sleeve. Spinnaker socks are popular with both cruising and racing sailors because they make setting and dousing a spinnaker easy, as well as protect your valuable sail investment. Widely used by both cruising and racing sailors, a spinnaker sock is a tapered sleeve generally made from a light, breathable polyester mesh. The Sailrite® Spinnaker Sock Kit features a white sock with a colored exterior pocket (pocket color varies) to indicate any twist in the sock. A continuous line is run through the pocket to raise and lower it, as well as keeping the lines from getting tangled in the chute.

Sailrite’s tapered spinnaker sock design is extremely effective and easy to make. This Spinnaker Sock Kit can be made on a home sewing machine. Scissors and a hotknife, wood burning tool or other tool for sealing openings will also be needed to complete the kit.

Please Note: This Spinnaker Sock Kit is for SLE (spinnaker leech length) of 42'1"–45'.

Ordering Information: For spinnakers, select the sock size based on the sail's SLE — spinnaker leech length.

I'm happy.

The project came together more easily than I expected. The instructions were clear and helpful. The result looks good.

Spin Sock Kit - Great for big boats, with one minor improvement.

This is my second spin sock kit, which I am making for a friend. The kit is complete, the instructions clear and the finished product works great on my old Cheoy Lee 38. One minor criticism and suggestion: The cheek block sewn to the inside of the hoisting line sleeve tends to bend the collar at the top, and jams if you need to pull hard on the hoisting line to deploy the chute. I made a 2-legged wire strop that attaches to the head of the sail, the halyard, and a bullet block for the hoisting line, and seized the wire rope to the collar just above the bullet block. Now you're pulling against the halyard directly, which is uber-strong and the hoisting line will not cock the bullet block and jam. The factory design is probably fine for a smaller boat with lighter loads, but I prefer my mod for a big boat.
