Here is the original string I read.  Scroll down to the post from Michael
Weisner to see where I got my information from.

In a post from James Nichols yesterday, he said that according to what he
had read,  Stan was installing 'Garden hose'
I suspect this is part of what Stan is referring to as mis-information.
I didn't mean to offend Stan with my keel boat story and appreciate his
suggestion for raking the keel back, but since he's too busy to provide
advice on this topic, I'll continue to search for the proper installation
and or a logical upgrade.
I have to repair my cracked cap and prevent it from happening again.
I still race keel boats in and around Sag Harbor, but I sail Dadventure in
my local shallows, and enjoy and appreciate everything good about the Rhodes
22 while I'm at it.
