Hello Folks,

Purchased some 8mm braid on braid sheets to replace over-sized old warn sheets but am finding that the the sheets are popping out of the traveler cam and the jibsheet clams on their own accord.

The only way I could manage to keep the main traveler cleated was by using a foot to stamp on the clam so as to encourage it to lock / cleat tightly but even by doing so it eventually releases the sheet. This method is not pratical for the jib clams as they are over on the opposite side of the boat.

Anyone else experienced similar issues?
Any ideas how to resolve?

Thanks,
SRG

To start the main and jibs lines are different.
Hobie line guide says:
Mainsheet Line (6:1) 3/8" Spun Braid x 44' 1 ea.
Jibsheet Line 5/16" Spun Braid x 32' 1 ea.

So 8mm is fine for your jib but you need roughly 9.5mm line for your main. Still 8mm should grab just fine on your main blocks so its strange that your lines are just popping out. Are your cams actually working freely? I always wash/clean mine after use and lube regularly to keep the springs tight. If they are super old perhaps they need replacing as the teeth have worn down causing them not to grab your lines or the springs have had it and aren't pushing enough force to grab the line.

It sounds like your cleats need cleaned and lubed.

What sort of cleats and what kind of new line are we talking about?

Do you maybe have a picture?

The type of line may be causing it to slip too. Is it stiff and or shiny? Sheets are usually fuzzy which grips well in hands and cleats.

Sorry for the delay in replying.

The main sheet is braid on braid 10mm
The Jib sheet is braid on braid 8mm

Looks like this Polyester Braid on Braid (Recommended by chandler) :

The cleats are the clam type, it could be that they need lubrication, will do that next time I am at the boat, will also check for wear and play:

Thanks for the info!

I don't see anything wrong with the line sizes/types. Unless there are broken springs, I'm betting the teeth on the cleat jaws are worn. It happens, even on the aluminum jaws. I don't think the jaws are sold separately. The springs are, but the better deal is the rebuild kit with springs, balls, etc.

I have never lubed a cam cleat. What are folks using for that? McLube OneDrop?

That is a smooth cover type line though. Not what we recommend, but you can rough it up by rubbing with some ajax in a bucket of water. Better grip means less hand fatigue. Glove are a MUST with that line.

Also make sure if that type of cleat is what you have (like many do on older 'upgraded" boats) that it isn't bent down to far preventing you from actually getting it cleated fully.. You can bend those things by stepping on them, and adjust them by carefully bending them by hand. If the lower swivel part of that cleat you picture is worn or broken badly it can create problems also.

Thank you all for your great responses!
Will definitely try the Ajax suggestion, the sheets feel rather smooth so roughing them up should help.
Checked the clam cleats and they appear to have adequate spring as suggested it could be that the ali teeth have warn but I do not have a new one to compare. Purchased some secondhand good conditions cleats off ebay.
Had a great day out on the H16 yesterday. Reverted back to the original jib sheet which cleats perfectly, its a softer line and old and rough, it does not run through the blocks as smooth as its a little too thick and old for a jib sheet but it does cleat!
