Jam cleat on a Cobra 850 for the furler line

[Rhylsailer99]

What would be a good replacement for this item ? its used for jamming the furler line, but the teeth have worn and the line slips now .

Similar still available, although not that exact design which I think is a Gibb. I had some very nice ones made of Tufnol which are longer lasting but don't think they are made now although often turn up in boat jumbles and the like. Alternative is a rope clutch but typically twice the price and a bit OTT for a furling line.

I use a Lewmar clutch - much better than a jammer cleat - just pull and release.

I'm thinking maybe to just put a horn cleat there, as I'm in the habit of wrapping the lines around the genoa cleat, but that gets messy with the 2 lines together on one cleat.

My mainsheet goes through a pair of these and it's now considerably worn and scruffy (to the extent that people remark on it).

I thought I bookmarked a while back a replacement which uses the same mounting but which supposedly grips the rope more gently / without teeth. I'm now unable to find the bookmark.

I think it was the Spinlock PXR Cam Cleat, but I cannot now find these claims about gentleness mentioned anywhere, so maybe I'm mistaken?

I shall check them next time I'm near a physical chandlery, but it's the version with the "Retro Fit Base" which is intended to fit the same mounting holes as a regular cam cleat. Looking at your photo though, it seems to have more mounting holes than my Harken ones though.

EDIT: what a coincidence! Was just visiting a neighbour and he has one of the Spinlock PXR cleats on his boat. It still does have teeth, but their profile / area is different, so maybe it will be less harsh.

I use a standard cleat suited to the line size. Seem too many jamcleats wear and slip. Cleat goes on forever.

I have some similar tufnol cleats on my classic Finn which didn’t grip very well. I took them apart, gave them a good clean and sharpened up the teeth with a file, they now grip fine, so you could try the same.

Cheers I will give that a try tomorrow .

Maybe this is a multihull paranoia thing, but is a rope clutch really OTT for a mission critical control? I absolutely would not trust ours to anything less. My goto advice would be to replave it with a clutch. Whilst primarily it’s security of the reffed sail in a breeze, it's also insurance that your sail isnt going to unfurl itself and get shredded on your mooring.

If I was going to leave a furled sail on a mooring, I would put a sail tie round it regardless of the type of clutch etc.

Ours has a zipped on cover hoisted up the foil with the spinnaker halyard.

Very "Dutch" but a faff if single handed

I often do it solo as Mrs is clearing up inside. Yes, it’s a pain in the arse. I pass the halyard round the winch and bring it out to the foredeck with me..

Hardly mission critical - not like a mainsheet for example. Cam cleats like that hold pretty well under load - in fact often more difficult to uncleat. On somewhat staid boats like the OPs you rarely need to touch the furling line except to make a deliberate change in sail size. As for unravelling when moored - if you really are worried about that then cleat the tail - but in my experience of using cam cleats on similar size boats they are fine on their own unless they are worn like this one. BTW, clutches are not foolproof and also wear over time.

I couldn’t give a damn if the main uncleats itself unless I’m in 1st place, racing. Then it’s just disappointing. I give very much of a damn if my jib suddenly doubles in area unexpectedly. Then I might need the lifeboat. Therefore my clutches are stripped, inspected and maintained every year

OK so you use clutches when on the OPs boat a cam cleat will do just as well. Why invent a problem that is not there! If you really are worried, just cleat it off - you don't need to use it for adjustment in an emergency. That is what I do on my current boat as it is not easy to locate a cam cleat or a clutch. When I get lower down my extensive "to do" list I shall invest in 2 of these (I have 2 furling foresails) as I fitted to my Bavaria. LOvely things but they come from Harken so not cheap. More than one way of solving a "problem" but you need to analyse it and choose the best option available.

Ok so the consequences of accidental release are not so bad on a lead mine. Various bits of multihull primary safety I couldn’t go back on now, if I bought a mono, and this is one of them.
