[C320-list] Knot meter cleaning.... In water?

[Jack McDonough]

Stephen:

Thanks for the suggestion. I'm sure you're right. But I've been sailing for 
25 years and I'll be 75 if I live through the end of September.
The SOG on my GPS is good enough for me. I guess I'm what you'd call a lazy 
sailor.

It is a Raymarine unit, by the way. And I haven't the foggiest notion of how 
to calibrate it. Mostly I'm concerned about having a couple of good books 
and a sufficient amount of scotch aboard. Sailing, for me, is not a 
competitive sport.

I don't mean to be a smartass. I do appreciate your offer of help. Really. 
Thank you.
