Sail Pack Kit for 13' Boom

Sew it yourself! Sail Pack Kit for 13’ Boom lets you make your own sail pack mainsail cover. A sail pack mainsail cover (also known as a Stack Pack®, Lazy pack, or Mack Pack®) is a popular adaptation of a standard mainsail cover that is used in conjunction with lazy jacks to make dousing and covering a mainsail quick and easy. Simply drop the sail and zip the cover panels shut. The two halves of the cover attach below the foot with webbing straps and common sense fasteners.
This stack pack mainsail cover is integrated with a lazy jack system (not included) to support the top of the sail pack and guide the sail neatly into place inside the cover. The sail pack is also designed with sleeves for schedule 40 PVC 3/4” pipe to keep the cover open when the sail is lowered, a zippered closure across the top, and a removable forward mast boot. Lazy pack attaches below the sail’s foot with webbing straps and fasteners.
The Mack Pack system works best with mainsails that have slugs or slides on the luff, but also accommodates a boltrope that runs up the slot in the mast. Sails with full length battens encourage proper flaking and work well with this system, but it also works with sail that have standard battens.
Each Sail Pack Kit comes with the sail cover instruction booklet that contains step-by-step written instructions. Approximate construction time is 5 hours.

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