Product Overview


$550.00 up to 10 ft  (305 cm)

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).

    Easy process, exceptional product and service

    If you are looking for a sail pack, look no further. Just provide measurements for your boom. I was skeptical of the process at first, but my cover was a perfect fit and it looks amazing.

    Nicely done

    The sail pack was exactly what I was hoping it would be. It makes dousing your mainsail effortless, just release the halyard and zip it closed. It was nice to be able to talk directly to Becky to ensure the correct dimensions and strap placement. The quality of the work is great, the price was reasonable and the fabrication was fairly quick.

    Job well done

    I needed a new sail pack with the purchase of a new to me Sabre 34. The first thing I did was contact 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.

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

    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!
