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.
