Progress on my 37C has been slow of late, but there are a few 'numbers' that are getting closer to being addressed. Anyone know:
The size of the clevis pin (mast end) for the baby stay?
Preferred angle setting for a Windex vane (60? 65?)
Dimensions for head/stay sails. (The boat has neither, but I'm about to get into the market for a set.)

Status report for my former mooring-queen is as follows: the original idea of leaving much of her mostly status-quo as found has long since given way to getting her at least structurally sound, mechanically stable, and even cosmetically improved a bit.
Of course, all this takes time and $. Speaking of which, I'm convinced my wife will appreciate my vision to a much greater extent once we have a boat that we can actually sail! :)

Thanks for any input.

Re: mixed bag of H37 dimensions

ybrad, keep working on it! You've got a terrific boat.

As for the stay dimensions, the clevis pin diameter is generally double the stay's diameter. This is a standard rule of thumb: very rarely are there variations (for example my H-25 is being upgraded to 5/32 rigging wire but will retain the 1/4 pins). I would GUESS that your inner forestay (it's not called a 'baby stay', which is a IOR convention for adding stiffness to an otherwise huge J dimension and NEVER flies a sail) is 1/4" and the pins 1/2"... but not having plans with specs in front of me I will wait and defer to Ed Schenck who may be the premier the resident authority on this boat.

There is a good site at mauriprosailing.com that gives the standard sailmaker's dimensions for most popular boats including Hunters. (They also interpret them for you-- if you are confused write down the numbers in order and then go to their home page again to decipher the data you got.) Sadly I do not have my dad's original sail plan drawing of my own boat-- I have been relying on an original 1975 blueprint at a local sailmakers' till I found this site. I thought I had these dimensions committed to memory... and found I was a little wrong on one of them. Oh well! :)

As for your Windex there's no hard-and-fast rule. You probably won't point much closer than 30 degrees; few boats ever do. Having a 60-to-65-degree span between the wire indicators is fine. Just don't do as I did-- make sure they're symmetrical! (-doop!)

Re: mixed bag of H37 dimensions

Thanks for the great input. I've got much to learn....it's all appreciated. Heading to the recommended website right now.
BTW, your dad sure came up with some nice designs. Here's to him!

I plead ignorance. It has been nine years since I refit my mast and I did not pay attention to those upper wire connections. You could give Rig-Rite a call after checking your mast information, I think #68106: http://www.rigrite.com/Spars/Kenyon_Spars/kenyon.html#Cruising Sections . I'll go through my files to get you my foresail(yankee) dimensions. It is slightly oversized resulting in my hardly ever using the staysail below 25 knots. Then I rolll up the yankee and run with staysail and reefed main.
