Best hardware for this attachment?

My boat has this (see picture) set up for attachment of the foresail. I have a hardware setup that I have been using, but it doesn't seem optimal. All of the other boats around the marina have a clevis pin kind of setup, so I don't know if I am doing this right. What is this hook device called and what is the best way to attach a sail tack to it?

Those are "tack hooks" The idea is that you slip the tack cringle directly onto the hook, and hoist the sail once in the foil or hanked on. Avoids shackles and pins quite nicely. The second hook is so that you can bend on another sail before dropping the first.

If you have a headfoil you can hoist a new headsail (smaller or larger, as the conditions dictate) before dropping the first and keep driving the boat - therefore you need the second hook in order to set that up. The longer flat part of the hook (which makes it somewhat less easy to slide the cringle over) also discourages having the sail fall off the hook between the time you set everything up and finally get to hoisting.

Many boats have similar setups at the gooseneck for reef tack points.

Thanks Faster. The setup I have now is a shackle around the "stem", secured by both hooks. The tack cringle is pretty large on the three foresails that I have and I'm concerned that it could fall off. However, if the halyard is the correct tension this won't happen?

Hi Eric,

Many racers employ a short length of shock-cord attached to the centre of the two hooks, with a loop that can be slipped around the hook opposite the one the fore-sail in tacked to. In this way the tack can be retained and will not slip off - important if you are flying a chute and will be dropping and raising the jib several times so the tack doesn't slip off as you suggest.

Cheers,
hugh

If you're concerned about the tack falling off, simply get some shock cord and fashion/sieze an eye in each end and then attach the middle of it to the forestay tang. You'll have to play around with the overall length and distance from tang to hook, but once the sail's hooked on, slip the eye of the shock cord over the tack hook.. this will prevent the sail from slipping off.

Sorry for the crappy graphic, but looking at the red line to illustrate how that would sit.. an eye in the shock cord would slip over the end of the hook. Set up for enough tension when installed to stay put. A double ended setup would cover both hooks.




EDIT: OOPS... cross posted with SFC....

Thanks again guys. I'll have to play around with some shock cord and knots to rig a safety for it.
