’07 Hunter 27 In-Mast Furler Failure

The in-mast furler (US Spar) on our ’07 Hunter 27 had a major fail late last week. As I was forward tidying up the jib sheets after furling that sail (we like to coil & tie off the sheets on the pulpit rail rather than keeping them run back to the winches), I heard a racket behind me and turned to see the main tumbling down. I yelled to the admiral at the helm, “Why did you release the main halyard?,” but then I realized she couldn’t have done that and still been behind the wheel! (There’s still some hard feelings about my tone of voice on that one… Oops!)

We were about to pull into an anchorage and drop the hook for the evening, and since we were 20+ miles from our home port, we just flaked the main over the boom and tied it up like the “old days” (sans the boom cover!). We motorsailed back the next day using the jib for a little boost, and since the wind was brisk and generally just off our nose for much of the trip, we didn’t miss the main.

When we got home, we removed the main to fold & stow it for the time being. What we found as we did so was unexpected. The problem was not that the halyard had parted, but that the furler headpiece/collar that attaches to the head of the sail and goes up the foil had somehow failed. Undoubtedly, when it happened, the released tension on the luff shot the headpiece up hard and jammed it there. Doh! We know the line didn’t fail because it’s still under tension back to the rope clutch. Further, the clip that attaches at the head of the main — and is closed with seizing wire to be sure it doesn’t slip off — was still attached to the sail!

So the main halyard is now stuck at the top of the mast. As for getting up there, the jib halyard is not only attached to the jib furler, which would make it problematic for hoisting someone aloft, but also we’re a fractional rig, so it still is a good 6’ below the top of the mast. (We don’t run a spinnaker, though there is a messenger line run should we want to add a spinny halyard at some future point… no help today!) So the only option is the topping lift. Unfortunately, that looks to be a 1/4” line, which would be a bit sketchy for a working load of someone 200+ pounds, as well as kinda hard to grasp under load. (Yes, we would use the winch to hoist, but coming back down, I think you’d need a good hold while on belay.)

Anyway, I called a rigger Friday morning (Bring Out Another Thousand), and as far as the masthead access/hoisting issue is concerned, he’s saying we could sew on to the end of the existing topping lift to run a thicker line, perhaps 1/2” or 3/8”, and it would be safe to put a full adult-sized load on it… as long as they don’t go to McDonalds too often…

But the main problem still remains: “What broke and how complex is the fix?” If the attachment on the headpiece for the clip actually broke off, then the whole piece will need to be replaced. I assume that scenario will require unstepping the mast, a fairly complex, time consuming repair, and then stepping the mast again (Bring Out Another Thousand... or two). If that’s the case, I think I’ll just finish the season as is, go a lot slower under jib only, and unstep the mast when we go on the hard in a month or so and deal with the repair at that point (we normally leave up the mast in the offseason). However, in the initial phone call with my new-best-friend-rigger, he said he had pulled up an illustration online of our furling system, and while the headpiece didn’t quite show full details, he thought that there might be a pin which holds the clip in place and perhaps that’s what failed. Maybe I’ll only have to bring out half-a-thou for that…

So there’s the sad tale as I know it today. I’m waiting to hear back from the rigger to determine when we can meet and figure out (1) how to get up the mast and retrieve the halyard, and (2) how to fix the failure. I’ll have to drive 3 1/2 hours from Mid-VT to Mystic, CT, but luckily (or not, depending on your point of view), I’m a theatre master electrician/stagehand and both of my primary venues are closed for renovations until next year, so I have plenty of time on my hands until ski season comes around and I start my instructor gig.

In the meantime, I thought I’d probe the collected wisdom here to be forewarned and forearmed prior to my meet and greet with the rigger.

Thanks, in advance, for any experience, strength, or hope!

Do you have pictures of what’s still connected to the head of the main? Thinking about the design of my U.S. Spars upper swivel I can’t imagine what parts might separate that would be repairable, but a Selden swivel might look different.

As to the rigger's advice about masthead access, I agree. In fact if I were to go up a mast, it would be with a line I know and trust. It wouldn't be the existing line which has an unknown history. The unexpected breaking of the swivel is testimony that s**t happens up there.
Since the swivel or part of it and the halyard are jammed inside the mast column I'm not seeing how you could bring it down from the top of the mast unless there is an access plate there. I think if done while the mast is down, you would have to remove the mast top to fish a line up there, to haul the swivel down. Prolly should replace the halyard too.
So, you've got a slow motor boat with a jib for a while... At least the boat didn't get dumped on shore by a storm causing a year long rehab. And you have skiing. Small violin.
BTW, I used to love listening to NOAH water forecasts on the VHF around this time of year while in New England. They would give the temperature atop Mt. Washington. It would be approaching freezing as I sat in the cockpit in a bathing suit. Gotta love that New England weather!

That's kinda the problem... it's stuck up there! Can't get pics! When we get it down we'll have an idea of what failed. It's a US Spar, so you're leading me to think full replacement of the swivel is probably in the cards

And thank both of you for helping learn the part that failed is called a swivel, not a headpiece.

There are a coupe of hex nut bolts with heads protruding that may provide some purchase to yank on it. Of course, I’m just assuming it’s stuck. It may well be it’s just there’s not enough gravity on the swivel end to let it ease back down. We may find it will come back down fairly easily. :pray:

And yes, I’m anticipating replacing all those lines aloft. The other thing I'm contemplating, especially if we have to unstep the mast for this fix, is replacing the standing rigging... but that's a topic for a different thread.

So, you've got a slow motor boat with a jib for a while...
Exactly! She’s a fun sailboat but a pretty crappy motorboat… still, there’s nothing better than being on a boat!

@shemandr, when the fail happened, we were just around the corner from your home port. In fact, we tried to get into Greenport or Stirling Marina last week, but apparently they have virtually no dedicated transient slips this season and you can only get in if a seasonal is away. Kinda bummed about that, but we had a lovely overnight at Cedar Island Cove, the special anchorage just to port after you enter Coecles Harbor. We'd definitely go back there.

Mine has a shackle that attaches the webbing in the head of the main to the swivel. The pin of the shackle goes through a hole that’s molded into the swivel. You said you got the main down and flaked it; was there nothing at all in the top of the main? If so maybe it’s just the shackle that failed, and once you get the swivel pulled down you could just replace that. If the shackle is still attached to the main then my guess is the swivel itself failed.

I've spent many nights there. During the week it can be very quiet (Pre-covid). Quite a contrast from Block Island and welcome. Just so you know you can usually snag a mooring north of the anchorage at Coecles Harbor Marine or transient dock space based on availability
Truth in advertising: I moved from the North Fork 3 years ago after living there for 20+ years.

Epilogue:

The rigger arrived late this morning and he swapped out the 1/4" line for my topping lift for a stouter line, then sent up his (120 lb?) helper to retrieve the swivel on the main halyard.

What we discovered is the cast iron hole in the swivel into which the clip for the head of the sail had lived was broken. Thus, the clip with the seizing wire intact was still on the head of the sail when I removed the sail:

Then we realized the PO hadn't been using the correct attachment point on the swivel. The correct hole has additional reinforcement you can discern at the top of the clip:

So I'm back in business! The only remaining question is how much he'll bill me for 2 hands for an hour each! Whatever it is, it'll be a lot cheaper than unstepping the mast, dismantling the masthead, replacing the swivel, then putting it all back together & restepping the mast, I know that for sure...
