Just installed a new main halyard on the boat, a SO 37. It has a Spinlock rope clutch sized for 7/16 or larger line. The new line is slipping when I hoist the main. Any suggestions as to how to remedy the problem??

The cam and base plate may be too worn for the new line. Hence you will start to slip.
Had that issue with my sunblock clutches $50 for base, cam and spring things are all well again.

If you are in a pinch to get it working, you can swap parts from a neighboring clutch of the same size. I found that a good cleaning with an old tooth brush and some soap (along with a little oil in the right spot) helped greatly.

When they manufacture rope they use soap for lubrication in the process. Washing the soap out of your rope will make it less slippery, and may help your clutch grab better.
What size halyard are you using? Is it at the bottom of the size range for the clutch? If so you can also move down a size on the cam inside the clutch. They are quite easy to change.

Hi All,
I had the same issue with mine and I ended up going a size up for the halyard, from 10 mm to 12 mm and the issue went away.
It was slipping from the day I got the boat... Happy now.
Cheers,
Allegria

I had completely forgotten that I had the same problem when I replaced my halyard. I used the same diameter, but the cover had less friction. My solution was to insert a length of small diameter cord into the center of the halyard where it passed through the clutch, increasing its effective size. It never gives me any trouble now.

We had the same problem with the halyard , we used to open and close the clutch twice with the rope still held on the winch this improved it a bit , to fully fix this we fitted a service kit and added a second clutch forward of the original now the halyard does not slip .

I had the same prob with my SO40 but left it as is since I had an extra winch on the cabin top and could leave the halyard on it.
On the 36i I race on we were having the same problem, so we added a cam cleat between the clutch and the winch. We have to take the halyard off the winch to put it through the cam cleat but that is not a problem as we use the cunningham to tension the luff.

My solution was to insert a length of small diameter cord into the center of the halyard where it passed through the clutch, increasing its effective size. It never gives me any trouble now. We had an odd problem in first few weeks, tufts from the outhaul outer kept snagging the self-tailing gear. The dealer said it would improve with age but it seemed to be getting worse. They replaced the outhaul with a much rougher one and that solved the problem. However, even that began to slip under tension after a couple of years. It has been reversed once and I also swapped over the cam the following year. I see that someone else has also used this method, easy to do and no cost as I had unused ones. It has started to slip a little once more and I'll try your tip of inserting some cord to increase the effective diameter. Thanks for this tip. |

Mistroma,
I used a 2.5mm utility cord from Robline, which is keeps its shape well. You don’t want to use one that compresses easily.
Most rope splicing techniques are much more difficult once a rope has been in service for some time. It was quite difficult to insert the cord into the new halyard. Try it near the end of the rope as a test, assuming your halyard is long enough to lose a foot or more if you’re unsuccessful and damage the line.
I inserted about 1.5 feet of cord, located where the halyard passes through the clutch. You would have to repeat the process if you wanted to reverse the halyard, of course.

Hi all,
Please read MartyB reply !! ,Spinlock will sell you reasonably priced service kit to replace all damaged parts. I did it a month ago and with one kit took care of all my (2005) 6 clutches that need part replacement,each one for a different reason.Amazingly efficient.
All in stock and ready for shipment.
Alex

And BTW, those clutches need some preventing maintenance. Once a year please rinse them with fresh water and let them have a shmire of any sort of grease on the metal movin parts.The reward will be lots of problem free operation. !!
