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 customerservice@leesailcovers.com (Not include: Lazy Jacks and #40 PVC 3/4" pipe).

5 J37 Mainsail Pack
Posted by Greg Howard on 3rd Sep 2019
Just finished installing my new Mainsail Pack w/ lazy jacks on my J37 & it fit like a glove. Measurement tool was easy to follow & Becky was great to work with. Also love the Weather max. I've used Sunbrella Cadet gray for years and it always fades to a greenish color after a couple of years. Hope the weathermax holds up better! Great price & great turnaround! Thanks,

5 Sail more, motor less!
Posted by Marc K on 21st Aug 2018
Before the mailsail pack, the sail was secured with a standard removable cover. Removing and reinstalling the cover was so much of a hassle, it was often decided by my crew against setting up and raising the sail, and instead to simply motor. With the new to mailsail pack, unzipping the cover to expose and setup the mainsail is a breeze. Now, we will sail more, and motor less. Material and craftsmanship is top class. I am a highly satisfied customer. Captain is very happy. :-)

5 Easy Mainsail Handling
Posted by Tim Prouty, Tucson AZ on 26th Apr 2018
The Main Sail Pack was simple to install and is well crafted. It works very well and makes sail handling so much easier. I love the zipper! I was challenged to figure out the correct way to run the lazy jack lines through the cover but it works now. I tied a loop in my topping lift line to secure the top of the Main Sail Pack at the aft end of the boom. I would not hesitate to recommend this product to a friend!

4 Excellent construction
Posted by Ji McMurray on 13th Nov 2017
While I haven't installed the sail pack yet, I have inspected it and find excellent design and fabrication. I'm sure when spring comes I'll have to trouble fitting it and will be happy with its operation.

5 Great for single handing!
Posted by Ed Long on 22nd Aug 2017
Product came quicker than expected and was a snap to install. I had two lazy jacks on each side of the boom and ended up disconnecting them from the boom and running them through the D rings on each side. Put taut line hitches in each side so I can slacken them before raising my main, and tighten when done for the day. If you keep your jacks too tight they will catch the battens, and that is not fun. Love the way you just flake the sail in and zipper it up. Easy Peasy! If it only came with Mud Dauber repellent.:)

5 One of the best investments I've made in my boat.
Posted by Brian Sams on 13th Jun 2017
From ordering to delivery, everything was great. I had a few considerations that had to be taken into account and they had no problem with that. The only thing that I would like to see is some better installation instructions, possibly a link to a video. In the end, it went on fine, but there was some head scratching that could have been easily avoided with some more thorough and we'll written instructions.

5 Perfect product for a DIY'er
Posted by Scott on 11th Jun 2017
So I finally installed Lazy Jacks. which meant that my sail cover needed modifying. Actually, the main sail cover needed replacing. Cost of mainsail cover replacement pretty much equals what you'd pay for this product. Just wish that I'd seriously considered this product before the lazy jacks. Everything works well, just that I'm probably going to have to do some lazy jack reconfiguration to optimize the use of this product.. Highly recommend for a DIY'er. Not that it's complicated, just there are lots of options to consider. For instance do you want to be able to pull the jacks to the mast or not; etc.
