I swear to God one appeared to have undone itself during this mornings race, is it a thing? Can they unwind if you don't really tighten the locking nuts (which makesthem ridiculously difficult to then adjust)

I'm using them alongwith staymasters on the shrouds so I can adjust the rig rake quickly, but iswear when I was de rigging one shroud was massively looser than it was when I went out.

Sounds about right, the nuts really are needed! Can't stand the things.

I can't stand chainplates and fiddly circlips I swear it's probably what keeps me from travelling all the f**king about mast up mast down, lighting boards not working, boats fallen off the trailer, if there's one thing needs a better design solution its shroud attachment.

Yes, its a notorious problem. Locking wire as well as the nuts is supposed to be the right solution. Obviously that makes them even more inconvenient.

Personally I use lashings and forged shackles to adjust shroud length and attach shrouds, but that's no good if you want it adjustable with repeatability.

Chainplates and fastpins maybe? But I'm just a little nervous of fastpins myself. The locking nuts do need locking up reasonably tight or the bottle screws will loosen, finger tight ain't gonna do it.

Get some wing nuts, you can do them up tight enough not to work loose.

Wingnuts, chain plates, get a Laser... Here's the news, it's 2021, the future you were never warned about..

We have that wire adjsuatble bidning system on snowboard boots boesystem is it? They use it on harnesses as well, dial the adjustment, surely something like that should be designed, where is the R&D in dinghyworld?

Then again what I really want is that Merlin system where you pull or release on rope to adjust the rig. Then again I want to be able to slacken the lee shroud to let the boom out further downhill, just a little flick switch, not much to ask, maybe one of those lever things contenders use on their forestay.

Oh and fast pins? Had the whole lot fall down thanks to a fastpin, so thanks but no thanks.

So your task Jim should you choose to accept it, is to find and post the secret Merlin diagrams and post them here.. Naturally your actions will be disavowed by the agency should you be caught and all knowledge of your existenced wiped.   (With acknowledgements to the Mission Impossible franchise)

I agree the best way I found was a braid eg dynema going up and down a few times to give a purchase. To mark the position I used to whip on twine at critical positions in bands one two and three to mark the “fast” positions
