My adjustable harness lines dont clamp any more ( buggerall use).I notice the grippers had corroded. I mentioned it to someone else & they said they had the same problem with their adjustable outhaul system.If you dont wash them in freshwater every sail they corrode & then the gripple system is gunked up & doesnt grip.You should be warned when you get them that they need to be washed or they should have instructions to that effect.I think I moved them twice.Ive taped below the grippers now so hopefully if they slip they'll get caught up & hold.
Grr..[}:)] Ive wash my gear in fresh water just not the harness lines.
At least I shouldnt have any more @##@#!!!! sails now..
yeah it's a real bugger. i had a pair of north adjustable with the metal buckles do the same. 
the pair of north i had before that had plastic and were the best lines i've ever owned.
now i only buy ones that use plastic. the double clip pryde ones i have are also very good.
am also getting a set of standard dakine adjustable that have plastic buckles.
Hey - but how's the new board treating you? Even my missus is interested, and she's got zippo interest in my own gear! Next instalment please.
I've got a pair of what appears to be called the "race vario harness lines" on this page
www.neilpryde.com/?Itemid=163&id=138&option=com_content&view=article
Had them for 2 years now, never been washed (because I'm lazy), and used about once every week or so during the summer.
They're also really easy to adjust while sailing.
..or suck...[}:)]
Avoid anything with a strap and buckle (eg. Chinook in-flight), the strap salts up and becomes so stiff that it won't adjust.
Avoid anything with moving parts (eg. North vario), salt and sand get in there to stop things working.
About the only thing we're left with are V-jam cleats, the Dakine set I bought were useless because the sewing for the boom attachment was way too close to the edge, ripping out after just one month, making me buy some webbing to make some new attachments.
So that leaves Flying ObjectsSailworks (Edit: it was dark in the shed 
), which I'm quite happy with, I'll be buying more when my current set give up:http://www.boardcrazy.ashop.com.au/p/382902/sailworks-adjustable-harness-lines.html
As for outhaul, never had any problems with my chinook setup, my cleat doesn't corrode at all, doesn't move once I put some plumbers tape underneath the plastic clamps, and works a treat.
These are the go, expensive but very good.http://www.chinooksailing.com/products/product_info.php?cPath=6_52_53&products_id=139&osCsid=1483b1c03e667361bcc363413bd71727
I have had them for about 14 months and they have been brilliant.
If I was to pick a down side it is a possible harness line twist and being trapped under the sail, this has not happened to me yet.
These harness lines could even move me away from the adjustable hook on my waist harness to a fixed set-up.
They were the other ones I had to choose from but being a cheapskate I went for the others..great move that was..
I think my ajustable ones are ProLimit, the clamp is plastic so it does not erode and they're fairly cheap here.
The metal ones you should keep away from :)
Hey Sbc from memory I bought the same cheep (My*t*c) adj. lines around the same time as you from the same place.
My only gripe with them is the rope stretches
But as far as the metal clamp goes it's the same as North and Prolimit and with all of them you have to aim the hose at the spring and the pin to wash them out and occasionly spray with CRC or similar and you'll never have a problem
IMHO they are still the easiest to adjust while sailing
I also have the Sailworks ones on another boom and although a great
'simple is best' system I find the harder to adjust and abit too floppy.
Is CRC like WD 40 ..?
Yeah WD40 all the same stuff,
try drenching the hinge/clamp/webbing with it while working the lever to try n free it up
Of course if the teeth or spring are corroded away you'll have to trash it or tie a knot in it and use them as fixed lines
.oh well ill keep taping it up below the jaws..
Perhaps try CLR to remove the rust?
Just took a photo of my sailworks cleat:
No rust at all, and if they were going to rust, they would have started by now...
Just buy fixed lines, that'll fix your problem. I used adjustable lines when I first started but found they slipped. I just have one set of fixed lines now that I use on all of my sails, eight in total from 4.7 to 8.5. Just find the length that suits you and stick with it....Never found a need to keep adjusting once I found the sweet spot.
Don't know if it makes a difference if you use a waist or seat harness, I use a waist harness and have never tried a seat harness.
How's the Rocket going?
Cheers...Jase.
Mauisails make a good adjustable harness line. The Windsurfing Shed sells then for around $40.
Why did it take me so long to work it out? But I did enjoy cruising around in said conditions & I got 1 planing run at the end so its fullfilling the use i bought it for.Its just that its SO MUCH FUN when the wind gets 10kts + that I just wish it would #@#$ blow!! I want to see what my top end range is before I find the chop makes it too big to be fun.
