Hi Chuck. For my preventers, I have 2 lines with eyes spliced in one end at forward end of boom. The other end is attached to the back of the boom. Then I have 2 lines going from cockpit forward to standup blocks on the foredeck. These can be also used for pole downhaul. When I'm not using the pole I will bring the lines back to the mast base. Here I can set the main sail grab the line off of the boom attach the preventer/downhill line using the installed snap shackle. I was in some nasty seas sailing down the coast of Oregon. I had both preventers attached to both downhaul lines. When I gybed I was able to loosen one while simultaneously tighten the other allowing for a controlled gybe. Email me off list and I can send you a picture.

The reason we have big strong 4:1 mainsheet as a preventer is lost in time.

The first test of the 4:1 mainsheet was a resounding success, it works great in light/medium air. I still need to grab the 6:1, I can see this being beyond my strength in heavy air. This brings up a new issue, the preventer. Since what was my preventer is now my mainsheet, I did not have a preventer and really hate running wing and wing without one.

Stus-List Re: 35 MK I Mainsheet and Vang
I would recommend a 3:1/6:1 arrangement with double line, something like this: https://www.dropbox.com/sh/aktbkuov19c4q9y/AACSrPhw1Xq758Tk8U7fae1ea?dl=0. All blocks are Garhauer. The special double block, double cam was around $75. Mine is a 27 ft boat, so the forces are respectively smaller. Originally, it was a 4:1, two-ended, with one end on the cam cleat and the other on the winch. Going upwind in any fresh breeze, there was no way I could trim by hand (at least, not easily). With the 6:1, I never had problems, even at strong winds. The 3:1/6:1 arrangement eliminates the issue of having too much line for e.g., gybing. NB. I don't think this would work well with a dodger.

4:1 is not enough in heavy air. As you increase the purchase (6:1), you will have more friction which makes it more difficult to ease the sheet in light air. Also, as you increase the purchase, you will have a longer sheet, and it will take longer to sheet in and out. I have a 4:1 purchase plus a mainsheet winch.

I had 7:1 purchase with end boom sheeting and ratchet block at the bridgedeck traveler and that was bearly enough at above 15 kts apparent on my 35mKII. She had a higher than normal aspect ratio mainsail owing to the slightly less than 12 foot E dimension. I think 4:1 won't be good in anything but light air and definitely not good for not so strong trimmers.

Joe, My 35-1 has a 6:1 purchase on a Harken traveller, and I have to pull reasonable hard to get the boom tight in any kind of breeze. I don't think a 4:1 would do it. That said, in light airs the 4:1 would be nice. Maybe you could use 6:1 but drop it to 4:1 in light airs, which, having sailed out of Annapolis for 5 years, I know you get a lot of in the summer.

Stus-List Re: 35 MK I Mainsheet and Vang
Hey Joe, IMHO, Four to one may be underpowered for heavier wind, unless you take it to a winch. Not sure if your traveller is mid boom or end of boom. The system on our 34R is end of boom and we have 5 to 1 course and 20 to 1 fine and the higher ratio is needed when she's powered up which is anything over 8 knots going upwind when the apparent wind hits 14 plus. Saw something online that showed some boats like J-105s rig their mainsheet five or six to one for high wind days and unreeve a block and convert it to four to one for light wind races. You may want that mainsheet at Bacon's.
