Re: Mainsail Bolt Rope or Slugs at Boom

Slugs allow you to run the reefing ties around the sail only, not around the boom. If those ties are around the boom and too tight, you can rip the sail. Slugs also allow you to tie the clew reefing line around the boom rather than cutting holes in the sail or adding pad eyes to secure the bitter end of the clew reefing line. My current main is a bolt rope type with cringles in the sail for the clew reefing lines. Not a great way to set this up.

Re: Mainsail Bolt Rope or Slugs at Boom

it must have slots for the slugs in the mack pack to keep it from sliding off the boom in the middle. the stack packs that are used on a loose foot will have luff tape or slugs sewn on the bottom that slides into the sail slot on the boom. had that on an old boat, we used sail slugs in the slot and a piece of PVC pipe on top of the pack and tied the sail slug to the pipe through the slots so it would stay centered on the boom. we even made sail slugs by tying a big big knot in the small line and sliding it in the sail slot and tie to the pipe .You have an outhaul car then the clew is already set up.

Re: Mainsail Bolt Rope or Slugs at Boom

Sorry my bad you did say foot, but I couldn't figure out how that equated to use in a stack pack. Loose foot is the way to go. If your sail has a shelf foot in it though, it kind of leaves a lot of material laying around for not reason doing nothing. Might want to consider that as well. Perhaps sailmaker can recut?

As for the foot with slugs? I've not seen that except clew and tack. Or completely inside the boom.

When someone says boltrope I always think luff, my bad.

Re: Mainsail Bolt Rope or Slugs at Boom

Thank you for all of the replies! Dropped the mainsail, sail cover and genoa off this morning. After a long talk with the loft manager at North Sails, he suggested just as you did - loose foot and add slugs to the bottom of the stack pack sail cover. They're going to cut the boltrope off the foot and redo the clew.

Sounds like it will be easier to reef now also due to less friction where the reef lines passed through slots in the foot of the sail.

Hoping to get a few more miles out of these sails before fitting out new ones! ....I was seriously drooling over the new materials, laminates and cutting / shape styles they had on display.

It's hard to tell from the pic how your stack pack relies on the foot for support, but I am sure it is not a big problem.

My stack pack has slugs that secure it to the boom independent of the mainsail.
