Would someone be able to help with the size of shackle that’s used to secure the tack to the mast on a 97 Hunter 376? I‘ve lost mine and the boat is a few hours from home. I‘m looking for the diameter of the pin, and the inside width. I can find a 1/4” wide d shackle with a width of 1-1/8”, but before ordering it I’m hoping to verify that it will be wide enough. I haven’t been able to source a wider one. Any help would appreciated.

ON most boats the gooseneck is the point of connection for the sail tack. It uses a pin to hold the main tack in place, not a shackle.
Perhaps this site list will help you.
Search for gooseneck then look for the 376 in the description.

Thanks Jssailem. I should have used the term gooseneck in the beginning for reference sake… I saw those on the store too. I don’t need the gooseneck toggle, and I think the pin you referenced holds the toggle to the gooseneck base. I’m pretty sure that there is a wide d shackle that is used to connect the gooseneck to mainsail tack. I tried a 1/4” wide d shakle. The pin fit, but the hoop wasn’t wide enough. The one I have is 1”. That’s all the chandlery had. I was without a measuring tape and tried a quick measure with a fixed ruler, so I question how well I was reading it without parallax. I tried a 5/16” wide d shackle, but the pin wouldn’t go thru the gooseneck.ON most boats the gooseneck is the point of connection for the sail tack.

I’m hoping someone with a 376 picks up the thread and is able to give me an accurate measure so I can order the correct part the first time around.
Once again, the boats a few hours from home. It’s slow to order parts, await delivery, try it, reorder something different.This morning, I also sent a help request to the Hunter Owners Store and might hear from them too in time. They list a mainsail tack shackle for the H25, but nothing for the H376, nor have I been able to find the part in the owners manual.
Today’s fallback plan is to try the 5/16“ wide d shackle with a 1/4” Clevis pin until I find the right part. Still hoping for further help though to get it right.

Ok. I do understand the issue of being a couple hours from the boat. My boat is 250 miles away.
Wichard makes a 1/4" pin shackle.
A Pearson has a tack connection at the gooseneck that uses this type of tack connection.
This image has the connection reversed. The pin should be run through the hole on the gooseneck mast fitting.

Thanks again. I appreciate the assistance. The Pearson gooseneck looks narrower than that of the 376. The Wichard 1/4“ tack shackle you reference doesn’t show the width, but from the image, it looks too narrow. I did try a 1/4” x 1” wide d shackle already. It was too narrow.

Ok Rob.. what about this one.
www.fisheriessupply.com
It is 1 1/8" wide at the "B" opening and 1/4" sized pin.
There are additional sizes up to 3/8" and 1 11/16" opening.
The wide shackle would concern me. Why finding a gooseneck with that wide of a solid tack seems odd to me.

I thank you again. That looks like the part I spec’d originally…. I just don’t know if it will fit - I guess what I’m waiting for is to see if I can get an accurate measure from an H376 sailer if only to save me the time of ordering, waiting for arrival, trying it, and reordering something else. ….but thanks again for trying to find things for me.Ok Rob.. what about this one.

While at the boat on the weekend, I dug deeper through stuff found the misplaced mainsail tack shackle. Just to close off the thread and for reference sake. The Goose neck fitting is just shy over 1-1/8”. The shackle width is 1-1/4” and the pin size is 1/4”

Thanks for the follow up. Glad you found a shackle that works.
Is there concern that the screw pin might back out of the shackle. If so, you might drill a small hole in the extended end of the screw and thread a mousing wire through and wrapped around the shackle for security.
Looking back at the listing for the "Wide D Shackel", I forwarded to you from Fisheries, it might be a source of a backup.

I like that the shackle can be moused using this pin design.
Not a big deal day sailing, but if you cruise and your passages take you sailing for 24 hours, it is nice insurance to have the sail secured to the mast.

Thanks. It wasn’t just any shackle that I chose. It was the original one that was misplaced. I like the idea of drilling a hole through the end of the screw as a safety. I’ll look at doing that next.
As an aside, I think the 1/4” wide d shackle you sourced, like the one from Fisheries, would be a challenge to use because the B dimension is narrower than the Gooseneck fitting. The Gooseneck would have to be filed down to take the 1-1/8” shackle width. Spreading the shackle would splay it and likely cause it the pin holes to misalign in such a way that it might no longer take the 1/4 screw… a pin might be forced through, but I doubt it. My toolkit now has a spare 5/16” extra wide d shackle with a 2-3/4” long ,1/4” diam screw and double nuts on the outer end to keep it all together.
Thank you for all your thoughts and effort to source possibilities. Your time spent is graciously appreciated. It’s nice to bounce ideas around with someone else.
