 Topic: Main sheet cleat with a differencePosted: 16 Aug 11 at 1:19pm |

I tend to rig, and sail all my boats now with the main sheet taken off the boom.
This of course means that I cant easily have a cleat, which itself isn't a problem as i don't like to use them however.... I'm planning on doing the round Sheppy race again this year and I no from past experience that I cleat does make things much easier, especially as my arthritis isnt getting any better. So... Any one got any bright ideas. I'm not interested in any kind of boom mounted cleat and the boat in question is a national 12 so deck mounted cleats are pretty much a non starter as well as you rarely sit in one place for that long. Ideally I could do with a cleat fitted to me so that I can always reach it but I'm open to suggestions? There must be a market for something like this? Ian

Ian
As you know from the RS100 development, there was plenty of experiment with a flip flop cleat on the boom. It seemed to work well and I certainly liked the off boom sheeting, but problems arose when at the back of the boat downwind. It was difficult to get the angle to uncleat at times. However, that was when controlling a kite as well, but on a Blaze with a single sail, you may have less of an issue. I am sure RS could point you in the right direction. A simple way to improve it may be just to use a lashed spinnaker ratchet block. It doesn't have a cleat , but does ease the pressure. |

I've been using off the boom sheeting for many years ( moth, cherub 29er IC ) and recently XC s/h with a kite. I've modified a Ronstan ratchet + cleat, so the cleat is almost vertical down instead of 90°, and removed the loop, so that upwind the cleat doesn't engage, but a quick pull downwards will get it in the cleat for downwind + kite sheeting. ( and for being lazy upwind, the sheet will go in the cleat with a bit of foot pressure on the sheet )
I must take a pic... |

I think the issue is that an N12 is rear-sheeted and it is going to be difficult to mount a traditional swivel jammer on the transom. Is it an option to convert to centre-sheeting or lead the sheet along the boom and forward Laser style? Either way you could then mount a swivel jammer on the thwart or the back of the case? Other than that just replace the existing mainsheet block with a big (75mm) ratchet block, and/or increase the purchase of the mainsheet system.

I thik it will be centre sheeting off the boom Jamie.
You need something like this Ian:
Some pictures in Craigs Picassa account maybe useful.
Also in his blog he talks about rigging a carbon boom, with some besoke parts, i am sure there is something in there about that fitting:
Hope it helps,
Russ |

Ian, we're completely sold on the advantages of off-the-boom sheeting on the X1 and are convinced more and more boats will go this way in future.
We're using a Harken Ratchamatic as the last block before your hand, which helps a lot - the harder you pull the more it helps, and it works very nicely. However, the smallest one available is the 57mm I think, which is quite big I guess. Have you tried one of these? Has the advantage of course that in a big gust you can't get caught with it cleated.

iirc- the RS100 prototype used a ronstan/harken ratchet on an RWO base (inverted). Might be worth giving Alex a call down at LDC if he's around... it's going to be skeleton down there though as they're all partying/fixing/bodging/sailing in Weymouth at the moment.

Back in my N12 days I tried the centre sheeting arrangement and there just isn't room in a 12ft boat where there is quite a bit of hopping around and it does get in the way. Off the boom though to a rear bridle is good though. |

Like some other things - sailing is more enjoyable when you do it with someone else

Blimey I pop out to the garage and already have loads of reply's....
To cover off some of the points though in no particular order. Yes its a N12 that we are talking about that I like to sail sheeted off the boom (like my other boats of recent times, including the Blaze). This means that on a run the ratchet block is wrapped around my crews ear and she wouldn't take to kindly to that also including a cleat with its various sharp edges. So thanks for all the talk of various boom mounted cleats but they just arn't going to work. Plus a 12 is the most trim sensitive boat I have ever sailed (if your sitting still your in the wrong place) so it needs to work through an extreme range of angles and the solutions I have seen just don't handle this. I'm currently using an old Freddy ratchet block that is fantastic and for an hour or two long race is fine but I could be spending 5-6hrs hanging onto a sheet for the Sheppy race and I just know its gonna hurt. What would be a really neat solution seeing as i only want it for this one race would be a cleat or jam that is strapped to the top of my leg or some where else about my person so that it moves with me. Do the kite surfers, wind surfers use anything like that Ian

You need a cleat bolted to your hiking shorts. Trouble is, gybe suddenly and you'll end up in a right lot of trouble! Also, the downward angle from the boom is going to be a problem for any cam cleat.
