O22 mainsheet setup

[proto57]

The question of how to rig the mainsheet on O22's (with the blocks on the transom) has come up a couple of times. Here is a sketch I made of how they are rigged.

Mine is not rigged that way...

My mainsheet is rigged from the boom to a triangular metal plate in the backstay. There is a two-pulley and cleat arrangement, similarto that in your diagram, but all the tackle is in a line from the aft end of the boom to the backstay. Should it be done differently? The attached pic has the mainsheet in it, but it may be hard to zoom in on...

back stay rig

I checked the literature that came with my 78 oday and I also rig off the back stay.

New Idea

I have the backstay triagle rig but am changing to a new idea I just heard about. It's using a boom vang on each side of the cabin top attached mid point to the boom. The vangs each clear the companionway hatch yet allow really good control of the boom and will control any accidential jibes. The vangs are two part tackle with cam cleats as you show in your picture.

Yes... there is a later rig you describe:

George and Drew: At some point after 1973/74, O'Day went to the rig you describe. The backstay was in two parts, separated by the triangular plate. This plate carried a mainsheet block, and the sheet was rigged to that.I've seen this described as an "automatic backstay adjuster", as under increasing force, the backstay would tighten up. But I think the main reason they did this would have been to get the web of lines out of the way of the passengers and crew. I personally don't mind the lines, as I have them, on the early system, but I see the point. And the backstay system may allow closer adjustment of the boom to center... I'll have to compare with someone, sometime.As an aside, a happy coincidence happened when I bought the mast and rig for my boat. I bought my boat without a rig in Kingston, NY... and found a rig for it, four hours away in Pennsylvania. Ironically, the rig is the same type as mine... with a single-part backstay, no plate. It was lucky, as I think this rig is less common. Rich.

Early rig

I also have the earlier rig that attaches like your drawing. I don't like it, it is always in the way. I have been looking at the catalina rig, with the bar that runs across the stern and a travelier attached to it and blocks that run from the travler to the boom. Has anyone done this type of rig?

Mainsheet

I suggest you run the line that goes through the cam cleat through the rear most sheave on the end of the boom. Also, splice an eye in the end of the sheet that is going to attach to the cam cleat. Use a small stainless steel shackle to attach the sheet to the cam cleat. At best the "system" that was designed for the "22" is barely acceptable, lots of friction.I've has my "22" for 30 years....Good Boat!
