Actually, you might be surprised to discover how old this set-up is. Quite a few designs from Giles and Stephens (to name two) had end-boom sheeting arrangements that went back along the boom - but I digress...

My only gripes with this set-up (and it's just personal preference, I suppose) are (a) that when you're not hard on the wind, the sheets hang from the bottom of the boom (see below) which could be a bit nasty in an accidental gybe - hmm, headless Alex? - and (b) having the mainsheets leave the mast and go down for the deck as they do, does make for one more obstacle if you need to go forward in a blow:



..anyways, good luck with your project!

Headless Alex ? Headless Chicken ? AHA !! Headless PortuGeese.

They are the negatives yes, but we'll see. It was fine when we had the old Bluebird and just about bearable on the C28 but I'm not happy with the ratchet block setup we have now. Seems to me there are too many times when it becomes quite a struggle to release. Which of course is in a blow and she is desperately trying to round up and T-bone that ferry coming down the harbour. (Don't ask but yes , it did nearly happen once, albeit with the old rig and block. Scared the crap out of me I can tell you.)

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Hi
Here in Europe this system is called "German sheeting", it can be used both with mid boom and end boom sheeting.

One some boats the two ends of the sheet are spliced into an endless loop, that way you will never run out of rope.

I have a similar setup on my Beneteu First 38 with mid boom sheeting, but I have a 1:4 purchase with 3 separate blocks on the boom and a fidle block on the traveller. The turning blocks are fixed with dyneema straps at the boom neck and the chainplate.

Mast is already down for the winter but I can try to find /take some pictures.

This winter I'm planning to do an improvement to make single/short handling easier.

I will mount two clutches, one on each side of the cockpit near the aft winches. That way I can use the aft winches for both jib and main sheet.

Leeward winch for the jib, windward winch for the main.

That way I can operate both sheets from behind the wheel..

This obviously makes it a FAR superior arangment to the designs of the rest of the world. We could not possibly have come up with something so masterful since we are all idiots by comparison!

Sorry, all those years of working for a German company kinda pushed me over the edge.

Hi TC34
No offence, i'm not German. I'm from Norway.

This setup has it pros & cons as other systems.

On my boat with mid boom sheeting the alternative would be the original setup with the main sheeted on a smaller winch on the coachroof.

Knut,

I'd be very interested see your pics when you get them. The clutch block in front of the sheet winches , which I've seen discussed before, seems like a damn good idea to me. OK so its commonly used for halyards where the lines come back to the cockpit but it would seem to make good sense for a sheet winch as well. Particularly on a cruising boat I would think.

T34,

I am ready to stand corrected here but I have a feeling that this sheeting arrangement first came to prominence on a boat in the German Admiral's Cup team back in 19blahdeblah when the Germans were pretty much Numero Uno (whoops Nummer Eins) in European yacht racing.

Yep, Knuterikt is right.
We also do call this arrangement German sheeting.
The major advantage is that you can fine trim the main on either side of the boat. While racing and sitting on winward rail you can always trim it using winward winch regardless of port or stbd. tack.
This way you keep your weight on the correct side of the boat.
Extra appreciated on smaller boats or small crew.

I just had a thought that maybe the designer German Frers popularised it ?

Does anyone know ? This intrigues me.

This sounds interesting.. I'd be concerned if ever both ends were "clutched"... such setups have poor mechanical advantage tackle-wise (relying on the winch for power) and having to dump the mainsheet via clutch could be trouble.. but if only one end is clutched and the working end left winch only, it could work....

The only other concern I'd have would be a kink in the line coming off the winch jamming in the clutch when you're trying to dump the main in a hurry....
