WOOSH,
Thanks for the tip, I will certainly look for a copy. Your information agrees with a number of significant (but unofficial) sources. What was confusing me is that at the site I listed in my original post, it listed sail vessels above or below 22'' and power vessels above 15hp (with no listing below that power rating).
I recently ordered some portable naviation
lights (I have no power source on my boat) and I was in the initial stages of determining proper arrangement of those
lights. (I am in the midst of a complete restoration of my boat). I will look for the CG pamphlet you suggested.
I hope your spring warms up quickly over there.
Doug
