Vang line slipping in cleat

My new-to-me boat is forty years old, and it seem like some of the line is that old too...

Anyway, the vang line looked to be the oldest. There was a similar length of line in the toolbox that was also the same color, so I assumed the previous owner meant that as a replacement. Last night I took off the old line and put on the new one, and now it slips like #### through the cam cleat. If I give the cleat a little push then it sets, but otherwise after you pull on the line it pulls back a few inches.

So... Is it an issue with the line? I have no idea what it is, maybe it's cheap crud.

Is it an issue with the cleat? Should I rough up the gripping surface? Or lubricate the moving bits?

Or do I just use it a bit and the line will roughen up?

Here's pics:

Re: Vang line slipping in cleat

The new line is likely slipperier than the old one which is the immediate problem. The other problem could be with the cleat itself. There are springs under the cams and they may not be as robust as when new. Also the teeth on the cams may have rounded over the years. You might take the cleat apart and see what the possibilities are or see if you can replace just the cam cleat not the whole fitting. Before doing this compare how yours works compared to a new one in the store.

Good and helpful pictures by the way.

Back home on Lake Ontario after something over 36,000 nm circumnavigator. Not surprisingly there is a lot of stuff I want to get done on Ainia both cosmetically and functionally. Getting an early start so it will be ready to go for next summer (Lake Superior?).

I had a similar problem and it was the cam cleat, I took it apart, cleaned and a tiny bit of winch grease on the rotating parts, problem fixed... on to another problem...

Re: Vang line slipping in cleat

If you carefully look at that cleat in your picture, you'll see that only one of the cleat teeth per side is engaging with that line.
Id recommend to change-out the present cam cleat for a more 'modern' Harken-type cam cleat with 'finer' and different 'engagement/'toggle' angle' so that you will have 'several' of the teeth engaged against the line simultaneously.

Re: Vang line slipping in cleat

A quick shot with WD 40 or similar then manually work the cams if that helps then lube them with a good spray lube if it doesn't seem to help then just get new camcleats they are not that expensive

Re: Vang line slipping in cleat

The line is too thin for that jamb cleat.

See how the cleat is fully closed? If you have a bit of thicker line it may work better.

Or maybe undo the two screws on the U bolt, and bang the bastard together a bit more. Then screw it down again and see if that improves it.

Older boats often just need a bigger hammer.

Re: Vang line slipping in cleat

On a zero budget? Try filing the cam teeth a little sharper.
Agree you need thicker line to spread cams wider.

Re: Vang line slipping in cleat

It definitely looks like the line is too small for the cleat. I would either replace the line or replace the cleat. Making the cleat's teeth "sharper" is just going to chew up the line. You will find that a modern cam cleat will cleat and release much easier than those old metal ones. Easy releasing under load can be pretty important on a vang!

Re: Vang line slipping in cleat

On closer examination of the pic, it does look like you may be able to squeeze the cams a bit closer together. The bottom right Becket looks bent., and other is a gap in the base plate of the cleat. I would still think about upgrading the cleat.

Re: Vang line slipping in cleat

It does seem like the line is too small, but it's the same size as the line that was there before and that line worked fine. Maybe the old line was stiff and coarse from age.

I'm not on zero-budget, but dang the list of stuff to buy just keeps getting longer.

I'll try taking it apart and lubing it and perhaps banging the bits a bit closer together, just for the fun of fiddling with things, but I'll also put a new Harken cleat on the list for next time I order a batch of stuff.
