Steve, call me PI but as far as I'm concerned, a COB is what's left after I've eaten all the kernels on an ear on corn, and a ship will still be a "she", as long as I'm aboard. There are actually five genders in the human species (and that's not including surgical reassignments) and if any of the four "not male" types falls overboard and objects to me calling "Man Overboard!" I'll gladly keep silent.
Yah, in 50F water, everything has to be treated a bit differently. I'll bet your bottom paint works much better, too.
