Comparatively to other mainsail protections, with our Sail Pack:
The cradle is a fully battened bag with lazy-jacks that opens automatically and holds the sail when it is doused or raised. Extra folds when the sail is reefed stay in the sail pack, removing the need to attach the excess canvas with sail ties.
The top part that holds the sail head folds inside the cradle and the sail pack remains closed at the front with the lower quick-release fasteners.
Difference with the Classic model:
The zipper is sewn on the side of the cradle, this is why we recommend this model to people who have trouble closing the zipper when the head of the sail is high.
The zipper is completely protected under canvas so that UV does not damage it.
The (webbing) sail ties are inside and enable the cradle to be folded down under the boom and tie it, to uncover the full surface of the sail. This feature is appreciated by racers.

1. Check dimensions when we receive your order:
- We design your sail pack with the measurements that you have entered,
- We check the consistency of the whole product,
- We will contact you if we need to check the information.
2. Depending on your sail's foot type:
As requested, you can choose if:
- Your sail is loose footed, your sail pack will have a 10mm bolt-rope as standard. If you want a different diameter bolt-rope, please tell us in the comments section at the end of your order.
Or:
- Your sail isn't loose footed, it is attached to the boom. We replace the sail pack bolt-rope by a PVC strip. When fitting it, place the sail's bolt-rope in the sail pack PVC strip and slide them both into the groove on the boom.
In both cases, we include openings for the reefing lines.
3. About lazy jacks:
As requested, you can choose 3 or 4 ties on each side. They are strap toes sewn on the side of the sail pack, in which you attach the lazyjack lines you already have, or ones you can buy from a chandlery.
4. Comment: Battens are not supplied.
- Either you already have them on your previous sail pack and can use them in the dedicated sleeves. Our sleeves can hold a diameter up to 14mm or flat battens with a width of 30mm.
- Or you can buy them. The cost of shipping is higher than the cost of the battens, so we have decided to not include them, it is better you get them from a local chandlery.
