Here are some more pictures that I took today to add to my previous reply.
First, the day sailing cleating arrangement:

The racing cleat:

The 3:1/6:1 boom side blocks (not sure about the connection that I have mocked up with the white spectra webbing):

The 3:1/6:1 cleated off using existing cleats:

Hope this makes it clear what I am trying to do. I am very uncomfortable using the existing cleating arrangement but can't think of something better.
