In another post, couple days ago, we got off topic in a brief discussion
about the Gerr Downhaul for a hanked on head sail or staysail.

While on the boat today I found the reference and illustration in Richard
Hendersons Singlehanded Sailing (2nd ed) pp 132.

However, I also have a copy of the 1st ed and couldn't find any reference to
it there. (or at least there weren't any illustrations, as I quickly thumb
through it.)

I have scanned that illustration and text and now have it at:
