My Cal 36 had plain winches and jam cleats. Never a problem. The winch takes all the load. There shouldn't be huge load on the cleat. Plus, mounting the cleat in the proper orientation prevents the line from getting completely crammed into the jamb.

...assuming one has nice soft serviceable sheets of the proper size. Not 20 year old crusty Sta-set X.

Yes, and I've also tried to release a cam cleat when the sheet is under severe load. Both work fairly well, if you put enough wraps on the winch to reduce the load. If you don't, then neither works very well.

The trigger cleats that you mentioned earlier sound like an improvement, if you don't mind the price, and until the moving parts wear out.

I raced a 25' boat that I equipped with clam cleats, and they worked great, but each type of cleat has it's ideosyncracies. You have to adjust your practices to the different types of cleats.

Yeah, they work well and have no moving parts, no springs, no cams, and nothing to wear out. I don't think they are fading into obsolescence because they aren't functional. I think it's because they're old technology and out of fashion. I searched for new ones a year ago, and could only find small ones. Too bad.

Re: Cam cleat placement for jib sheets?

G'morning all - what a way to start. A quick search for a pic and sure enough, the jam end is forward hence the starboard sheet must makes a 1-1/2 turns about the cleat, which is what I do now achieving the jam between the first wrap and the aft pointing horn. So if forward is the correct jam orientation, there is no gain in changing the cleats = less effort.

That also eliminates the immediate quandary of horn cleat orientation although the attached pic (SunnySandy's Marine Clipper '72) shows the forward horn oriented outboard while RHR1956's pic shows the forward horn oriented inboard.

I'll take a gander at the other sailboats on the dock this evening, doesn't mean much since they are all idiots like me who keep their boats in the water all winter so they could all have it bassackwards.

Thanks again

Re: Cam cleat placement for jib sheets?

Your memory is correct. the jam cleat is mounted such that the line makes a 120 degree turn around the plain end of the cleat then the jam end. This makes the jump operate smoothly and securely.

I'm surprised that those are not jam cleats already. That's old and proven technology. The proper size jam cleats may not be suitable for the proper size dock lines. But dock lines get no priority over running rigging on my boats. Dock lines can be secured in any inconvenient way.

Re: Cam cleat placement for jib sheets?

It matters how the jamb cleat is mounted. I think it's supposed to be mounted with the open end away from the winch, and the narrow end nearer to the winch, but I'm not at my boat to refresh my memory. I've seen them used on boats as big as the C&C 44.

I just noticed that, when you do a google search, it appears that google is calling everything a jam or jamb cleat. In particular, a google search for "jam cleat" will produce photos of every variety of clam cleat, but it's hard to find an actual jam cleat, like the one Faster produced. Apparently, google's search engine isn't refined enough to use accurate nomenclature that recognizes the distinction between such things as jam cleats and clam cleats. Be careful not to let the weaknesses in google's search engine confuse you.

Re: Cam cleat placement for jib sheets?

If you have room to operate a cam-cleat 'straight' from a winch ..... your location of the cleat is dead-straight between you and the winch, consider a Harken 'trigger cleat' (mounted to an angled base). When pulled 'down' (hard) on the line, the trigger is engaged and the cam-cleat automatically fully opens No need to 'pull back' on a sheet and then release/disengage it from the cam-cleat jaws.

Sorry Faster - Thank YOU for the pic.

Sailormon6 - Shoot, if it holds on a 35, surely it'll do on my 24... I like it


RT?R1956 - and a picture is worth an awful lot of words.... got it....

I don't think my cleat is turned, rather its aligned fore-aft, perhaps I should turn the jam cleat style and be able to release a sheet gently, in control, with finesse.... darn - daydreamin' again.

Thank you all again -
