Taking advantage of the last couple of gorgeous days before we end our season and move on to winter time activities.

Sailing along quite pleasantly, when suddenly - "BJEUAX!" (it's a French boat...) the top of the roller furling system lets go, and our jib starts sliding down onto the deck and over the top of the lifelines. Matters made worse when my wife hit her knee on the emergency tiller cover as we scrambled to change positions so that I could gather the sail up before it slid completely down the foil. And, of course, it's Friday evening and I didn't get a chance to call either Beneteau or the previous owner/dealer who we purchased our boat from.

Can anyone ID this unit? Every have similar problems, care to share your solution?

We had the mast stepped and all re-commissioning including sails reinstalled by a local shop which was very highly recommended to us... The sail is attached to this unit, raised into place with the jib halyard - clicks "permanently" into place and the the halyard is retrieved and secured back to a loop near the bottom of the mast. There does not appear to be anything on the sail, mast, or other running rigging which could catch and accidentally release it. I've tried searching several furling system manufacturers, but this may be all the way back to 1990, and the components have changed enough that I don't recognize it on any of the sites that I've visited...

Ideas welcomed!

It's and ISOFURL. You can get replacement parts from Rig-Rite. However, Beneteau changed these units out years ago because of problems. You can also purchase a rotating bearing replacement top for this unit. Good Luck in you endeavors.

Make sure the...

"release lanyarn" was properly sawn into your new headsail and that it is working properly. I would convert system to a top swivel to be able to hold sail with a cleated halyard.

That's the one!

Thanks, Hutch (for the reply from Niceville :) )! That's exactly what I have! Now I can get started on servicing or replacing things, I'll be sure to contact Beneteau as well. So much easier to work on things, when you know what you're dealing with.

Benny - WOW! - that's a great reply too! We're in dueling reply mode here. I'll be kinder to Floridians from now on ;) (I lived in Daytona for several years and still have LOTS of other connections to other parts of the state as well).
