SEW IT YOURSELF - Make your own sail pack mainsail cover with the Sailrite Sail Pack Kit for 10' Booms. 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.
The stackpack mainsail cover is integrated with a lazy jack system (not included in this kit) to support the top of the sail pack and guide the sail neatly into place inside the cover. The lazy jack lines are strung from a point two thirds up the mast to webbing loops installed along the top of the sail pack. These lines can either be tied off at the loops or run through the loops and alongside the cover to boom attachment points.
Sailrite's sail pack kit design involves sewing sleeves along the top edge of the cover for battens or schedule 40 PVC 3/4" pipe (not included in this kit) to help keep the cover open as the sail is lowered and to reduce flutter when the sail is hoisted and the cover is flat against the sail. This stack pack sail cover design also features a long zipper along the top length of the cover for quick closure and a removable forward mast boot for closing off the front of the cover.
The system works best with mainsails that have slugs or slides on the luff as they encourage a neat flaking of the sail when lowered, but it will also work with sails that have boltropes run up a slot in the mast. Full length battens also encourage proper flaking, but the system will work with sails that have short battens.
Each sail pack kit comes with the Make Your Own Sail Pack DVD, a DVD featuring complete step-by-step video and written PDF sewing instructions to help make building this stack pack fun and easy. Approximate construction time: 5 hours.
