  1. Works really well!

    Posted by Unknown on 7th Apr 2022

    Great sail pack, works perfectly, and looks great! Order process and installation is also super easy.

  2. Job well done

    Posted by Steve - SV Wind Dancer on 28th Jul 2021

    I needed a new sail pack with the purchase of a new to me Sabre 34. The first thing I did was contact leesailcovers.com. I had used them in the past (7 years ago) for a smaller boat and am extremely pleased with the quality of work and the fabric that was used (WeatherMax 80).

    I received the new sail pack as promised and again was extremely pleased with the fit, quality of sewing, and fabric. They exceeded my expectations again and I would not hesitate to refer them to other sailboat owners.

    Job well done.

  3. fantastic product

    Posted by John Sprouse on 21st Jun 2021

    The mainsail pack for my Farr 46 is fantastic. Great workmanship and design. This will inspire me to do more singlehanded sailing

  4. Excellent Quality and Value

    Posted by Mauricio villegas on 3rd May 2021

    Purchased a sail pack for myC30 and was at first nervous about ordering online and it not fitting right. However, Becky was really helpful talking me through taking the measurements and the pack arrived in less time quoted. I installed it in no-time at all and it fit perfectly. Went sailing this weekend and used it for the first time and it’s a real time saver.

    I will also note that my dock neighbor ordered his sail pack from a local sail shop at the same time or just before I did and he is paying about %50 more than I paid and he is still waiting for his to be made and delivered!

  5. Could not be happier!

    Posted by Warren on 27th Jan 2021

    Happy to have this new sail pack for my 36’ catamaran. The quality, fit and finish are excellent!! The turn around was fast. Thank you Becky for doing such a great job! New customer for life!

  6. My second time around with Lee Sail Covers

    Posted by John Boyer on 4th Oct 2020

    I've owned two trimarans and bought two sail covers from Lee Sail Covers. Great value and customer service. A lifelong customer here.

  7. The boat looks great!

    Posted by Unknown on 2nd Oct 2020

    Excellent product, fit perfect!

  8. Great product and service

    Posted by Tom on 10th Sep 2020

    Ordered this cover for my Windrider 17. Certainly not a standard but Becky and all were great in answering questions and perfecting the measurements. Quality and fit are excellent. Operation is super easy for a boat that is mostly singlehanded. I would recommend this product to anyone.

  9. Another WIN from Lee Sail Covers!

    Posted by Michael McGouran on 10th Jun 2020

    This is my second sail pack from Becky and I cant begin to say enough about the quality of the materials, craftsmanship and customer service. Awesome is an appropriate term! We have recommended her to many friends in our marina and elsewhere and everyone we have talked to has been very happy with what they ordered! Thank you for such great value!

  10. 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!


  11. 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. :-)

  12. Good Stack Pack, Great Price

    Posted by Ryan on 29th Jul 2018

    Just put my newain sail stack pack on and it looks good.

    I will review again in one year as to it's durability.

    So far I am very pleased.

    Still have to install the Lazy Jack's on my mizzen mast and then I'll put my mizzen stack pack up too!

  13. 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!

  14. Quality Product!

    Posted by Daniel Reagan on 21st Nov 2017

    I am very pleased with the price, quality and workmanship of this product. It is a perfect and makes getting on and off the water much easier for my trailer sailor. Thank you so much!

  15. 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.

  16. 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.:)

  17. 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.

  18. 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.

  19. Great experience so far

    Posted by Nick Martin on 25th May 2017

    Lee provided on the phone help with properly sizing and ordering and the cover came quickly. It installed easily and seems to work well, looking forward to our first sail. Had one issue with one of the tabs for the lazy-jacks wearing through as I installed the line, but it's held.

  20. Very nice quality - limited documentation

    Posted by Unknown on 11th May 2017

    I was very happy with the ordering process and quality of the product when it arrived.

    Some suggestions to get that last star:

    1) Make sure and mention you expect a topping-lift - my boat doesn't have one.
    2) Provide guidance on sailing with one (e.g. how much should I slack the lines, how to minimize windage, etc)
    3) A little more guidance on measurement and how much 'slack' is in the numbers - I measured pretty carefully, but the final product is pretty generous in size and probably could have been smaller.
    4) I'd like to see D-Rings on the loops used to attach the existing lazy-jack lines - suspect that will be initial point of failure since it's where the load is held
    5) I may have gotten the length a little short because measured to the end of the sail instead of the end of the boom - and while furled so it was back a little bit - emphasize that it's boom length that's important (since it attaches there...)
