How to Make a Sail Pack Video

Item # X-HT-200598

Are you looking for a quicker way to flake and cover your mainsail? Have you tried using a sail pack? Sail packs are an adaptation of traditional sail covers that work with a lazy jack system to make setting and dousing your mainsail quick and easy. Our How to Make a Sail Pack Video highlights tips, techniques, and step-by-step instructions for making this popular sail cover.

Sail Pack Installation

Sail packs are held upright by lazy jack lines and stay in place while you sail. The pack is always open and when you are ready to lower the sail, the lazy jack lines help the sail to flake neatly in place inside the cover. This sail pack design features sleeves for battens or PVC pipes to be inserted along the top, which helps keep the cover open during flaking and reduces flutter when the sail is hoisted.

This sail pack is made from Sunbrella® Marine Grade Fabric and features a long zipper along the top of the cover for quick closure and a removable forward mast boot for closing off the front of the cover. In this video you will learn how to measure your sail and pattern, sew, and install a sail pack.
