Main Sail Tack Attachment

Removed the behind the mast furler from my refit project and am left with figuring out how to attach the mainsail tack. I'd like to retain the furler goose-neck and mast attachment and make something work with what's left. Any suggestions on how to approach this without removing everything and staring from scratch?

First picture is with the furler removed and the attachments in their original place, second picture I switched things around, thought maybe I could use this setup replacing the L shaped bracket with a bolt to secure the boom. Not sure if the attachment point in this configuration will pivot with a main hoisted, it will with no pressure on it.

Any suggestions?

Re: Main Sail Tack Attachment

It seems as if the main, even if it is loose-footed, will chafe on the pivot.

However, I have no engineering expertise, and so, no helpful suggestions to offer. There are a bunch of people who know lots more than me, and maybe they'll chime in, soon.

Re: Main Sail Tack Attachment

Are you reusing the same main or getting a new one? If getting a new one, the tack set back can be, within limits whatever you want. If you are reusing the same one, the set back will limit your pin placement. You may get away using a shackle through the holes in your current pin and use which ever hole it best aligns with. Also you can get different length shackles.

Re: Main Sail Tack Attachment

The slot in the mast is for the sail slugs for a conventional main set up. No need to add a track. Will probably have to cut a gate into the mast/track to load the slugs but that's the way it's normally done. Might have to replace the fitting for the furler with an eye bolt and use a shackle but that hopefully would be just unbolting the furler fitting and substituting the eye bolt. The furler fitting slot looks to be too narrow for the tack of the sail though a shackle may work. Will probably have to modify the tack of the sail to fit the offset of the boom hardware. If you are getting a new main, the sailmaker will handle that.

Re: Main Sail Tack Attachment

in the second picture, yes you can replace the L with a bolt, but...... (always one of these)
Do not use a machine thread, as you do not want the thread itself bearing on something. If you can get the right length blank bolt with a thread on the end so the nut and washer take the entire thread length then that is perfect, otherwise, you will need to go over-length and run a die down there to extend the thread - finally cut off the surplus thread beneath the nut, or fit an eye or similar if that will be useful.

Re: Main Sail Tack Attachment

the second pic looks good with the exception that the hole in the yolk at the tac is a little high. bring it down and the foot of the sail will run straight. wrap the bottom of the tac with leather and that will handle the chafing at the pivot point. I assume that the yolk will turn with the sail? if your running a free footed main then, nothing needs changing from the second pic, with the exception on changing the picot pin to a bold or long clevis pin, for clearance.

Re: Main Sail Tack Attachment

Cut the bottom 8 or 10 ft of the luff back so that the tack cringle fit to the tack fitting. Add rings to the bottom few slugs in the cutback area, and rig a luff jackline. Blue's works perfectly.

Re: Main Sail Tack Attachment

The existing main can be modified too - to allow for the new placement of the tack horn/shackle. Roughly USD150 at a local sailmaker.
