Throated Sail Cover Kit - Standard Sunbrella Color (Booms to 13')
SKU: 1152

Please Select an Option Above



Sew it yourself! Sail Cover Kit for Booms to 13' lets you make your own mainsail cover. Cover and protect your mainsail when flaked with this throated sail cover. The sail cover fastens under the boom with Twist-Lock fasteners with a snap button finish to provide a clean look and reduce chafe. Secure the cover around the mast with a marine zipper. This sail cover pattern features pre-plotted, long-lasting Sunbrella fabric for easy construction. Approximate construction time is 4 hours.

To determine which sail cover kit is right for your boat, measure the length of the boom (dimension "E") from the mast to its end (not including the mast width). Choose the kit with a length equal to or greater than the length of your boom.

Note: Maximum Boom Length - 13'

Lazy Jack Slits: The mainsail cover pattern instructions include directions for creating lazy jack slits. If required, order an additional 6 feet of 1" acrylic binding tape, an additional yard of Sunbrella fabric and 3 to 4 Twist-Lock fasteners for each slit. Ordering 1 square foot of 2-3oz. leather should accommodate up to 8 slits.

Inclusive kit

The "first draft", before zippers and snaps, looked very nice, but someone else made it and we don't have it yet, so I can't do a full review. The kit included everything needed.

Great kit, initial tight fit but fixed with a positive remedy.

Great kit and directions clear. Initially to small for a crunchy new sail and fit was tight. Materials were high quality and I would recommend it for a first time project. Thank you Sailrite for finding a solution to the tight fit. I look forward to doing more projects as was rewarding to do.


Love this kit

I ordered this kit to make a replacement cover for our Corsair mainsail. The kit came with everything I needed and a wonderful instruction book. The fabric comes with 2 pattern sizes plotted on it. Our sail is carbon fiber and required the larger of the two sizes. This was an easy project that produced a very professional looking cover for a very reasonable price.

Arrived quickly. Appears to be complete kit . Haven't started yet so no further review


Great kit, there are some caveats...

This is a great kit, has... almost everything you need. If you have a heavy duty home sewing machine you're going to have a bad time. The thread supplied with the kit is too heavy and you'll need to order the lighter
