Product Overview

Add $37.50 per foot over 10 ft

A mainsail pack (also known as Stack Pack*, Lazy Pack, Mack Pack*) is popular with boats that use a lazy jack system. Simply drop the sail into the pack and zipper to close. The mainsail pack 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. At the foot of the cover there is 2" wide webbing every 12" with twist lock closures to either go between sail slugs(if you have slugs on the sail foot) for pack to sit above the boom, or the 2" webbing to go under the boom.  Any questions please feel free to call (800) 516-2703 or email me at  (Not include: Lazy Jacks and #40 PVC 3/4" pipe).

    We love our new stack pack. Fits like a glove on our Pearson 36-2. Highly recommended. Very easy people to work with, timely delivery and high quality. Thanks Lee Sail Covers!

    The pack could be 5 stars but I am not sure a new sail would fit. I did put it in my notes. The design and construction is very good, and trhe service was very fast. I would buy again.

    It fit exactly like I had hoped. The material was better than sunbrella. There are now 3 less sailcover main oaks on our sailboat dock.

    Very pleased with the new mainsail pack for our Jeanneau Catamaran. The WeatherMax 80 is fantastic material. Becky was the absolute best to work with and we had a lot of discussions about what I wanted and how to make it. She was very patient and listened to what I needed. She built a very good product the way I wanted it and at a reasonable price . Definitely a GREAT experience . Thanks again Becky. I would recommend Lee Sail Covers to everyone wanting a really good product for their boat.

    We run a catamaran charter in Charleston. Just finished putting on 2 new mainsail pack covers and they are a great fit! Lee Sail Covers called after my online order to double check measurements and I ended up making some adjustments and I am glad I did. Their suggested adjustments were spot on!

    The sail pack looks and fits great on my Catalina 30. I added 2 10’ pieces of PVC on each side from Home Depot. Easy install.
