Gary Hendrickson (x-Markia) informs me there was an article in the class newsletter (<1992) with an equipment list for improving the purchase from 3:1 to 4:1 for the keel block and tackle. I'm willing to reinvent the wheel, but would welcome a copy of the article (or comments) if anyone has this article available.
I assume improving the purchase is ok with class rules, stop me if it's not.

Did you get what you need in response to your post regarding improving the gear ratio on the keel lift system? If not, email me directly (sr@keleher-law.com). I believe I have a copy of the instructions which I can send to you.

I am in the process of repairing my keel. Would be interested in seeing the 4 to 1 diagram.

Would you forward a copy of it to me also? I'm in the process of upgrading the keel lift.

I just had a stainless steel padeye welded to the bottom of the lifting plate at the bottom of the part that covers the block. There is not a lot of room for additional hardware so you have to keep the padeye as low profile as possible (about the thickness of the rope. I put a harken double block on the arm coming up from the keel. I put aircraft grade stainless steel nuts and bolts in the hardware. You need a colbalt drill bit to drill the stem of the keel and to drill out the holes that go through the sheaves on the blocks. I was able to use one of the holes from the original block. The stem of the keel on our boat does not stand straight up and the torque from the new mechanism made it bend so that it would not go through the slot in the plate even though the line and blocks are straight. I ended up putting in a piece of stainless from the stm to the top of the keel to keep things aligned.
