How to Build a Spinnaker Sail Kit

Item # X-HT-102743

Sewing your own spinnaker sail is fun and enjoyable, though it is a project that takes a lot of time and attention. It’s an easy type of sewing DIY, so you don’t need to be an expert sewer to tackle sewing your own spinnaker sail. Watch our video series on the steps involved in sewing a spinnaker using a Spinnaker Kit from Sailrite®. Sailrite will customize a spinnaker to your exact specifications that will fit your boat perfectly.

We make it easy to sew your own sails by preplotting all the matchup lines on the sail panels so all you have to do is baste them together and then sew the panels together. It’s that easy! Our how-to videos will walk you, step by step, through the process of assembling and sewing a spinnaker. Let’s get started.

In our first video, we baste together the panels with Seamstick Basting Tape for Sailmaking & Vinyl. This can be a time-consuming process, but take your time and make sure you match up your marked lines exactly. It’s easy to peel the panels apart and realign them to get them exactly right. Then sew the panels together using a zigzag stitch sewing machine. We’re using the Sailrite® Professional 4-Point Sewing Machine to sew our spinnaker sail and sewing one row of 4-point zigzag stitch per panel. If you don’t own the Professional, you can also use the Sailrite® Ultrafeed® LSZ-1 Sewing Machine and sew two rows of 2-point zigzag stitches on each panel overlap.

In the second video, we’ll show you how to do the patch assembly for the sail. There are two options to doing a patch assembly: grommets webbing and corner rings. When you order a Spinnaker Kit from Sailrite, your Spinnaker Kit Instructions will tell you whether to use grommets or webbing and rings in your sail. In this video we’re using grommets. If your instructions say to use webbing and rings, skip ahead to the third and final video in our series.

In the last video of this asymmetrical spinnaker series, we show you how to install the patch assembly using webbing and rings. Again, refer to your Spinnaker Kit Instructions for which method you need to use for your sail. Watch this video for the last part of sewing your own spinnaker and any final instructions and advice.
