Lee:
Good for you getting out in these blustery conditions. I thought about
venturing out this afternoon but the wind howling through the rigging kept
me idle at the dock. I am encouraged to hear that you are getting to
within 45 degrees of the wind. I have not been able to do that. I will
give it a try on my next venture out and report back.
