My rope clutch for the halyards has a broken handle and both sides slip. This is the clutch on the cabin next to the winch for raising the main & jib. The winch hande hits the clutch, probably why the handle was broken when I bought it this year. I’ll move the clutch forward so the winch handle doesn’t hit it.

I’m going to order a new double clutch and need to know the rope size, but I don’t know the rope size.

My rope halyards are the same size rope as the main sheet lines, so what size are they?

Ummmmmmm... (5/16ths is common for C-25 halyards, but...)

The manual has them at 5/16".

Cut off the end of one and take it to the store. i.e... cut off the bitter end where it ties to the shackle/ knot at the sail. This moves the place on the halyard where the halyard lays over the sheeves and where it is grabbed by the clutches and wears. The halyard will last longer.

It doesn’t matter how far the sail goes up, full, reefed, in between, etc.. the clutch slips and releases on its own sometimes. It’s worn out. I’m pretty sure it’s 30+ years old.

If you have wire-to-rope halyards (original in '86 I assume), they're almost certainly 5/16". If you have all-rope, I'd guess a P.O. replaced them, so they could be different, such as 1/4", which could greatly increase the likelihood of slipping in a clutch sized for 5/16-3/8" (8-10mm) rope. One way or the other, you want to match the line to the clutch.

Im advising to find out the size of the line.. and as long as you are doing it if you cut the end near the sail it will make the halyard last longer.

My boat was 5/8?? but I changed sheaves and halyards to 3/8 ( same line size as my sheets, easy to remember ) Many owners may have changed sizes for many reasons when they quit using line/wire halyards.

And some have gone to 1/4.

And some 5/16. and some 7mm.

You might want to measure.

The original (and CD's replacement) mast-head sheaves are for 5/16"--anything larger (especially 5/8") can be too large for the sheaves, adding friction, making sail dousing more difficult, and causing damage to the sheaves unless they're aluminum. Smaller (1/4") is just a little harder on the hands, and I don't know if there are any clutches for that. (Cam cleats would work, but halyard tension can make them very difficult to release. That's what clutches are about.)
