What is the nautical origin of the phrase “By and Large”? 

Send your answer to cruisingcompass@bwsailing.com. The winner, selected randomly from correct answers, will receive a Blue Water Sailing hat.

Thanks to last weeks winner, Fred Leedy, for his answer to the question: What does CPA on your chartplotter indicate?

Fred says “I’m old fashioned and don’t have an electronic chart plotter, but back in the early 1960’s when I was keeping a RADAR surface summary plot aboard ship, we had orders from the captain to keep all surface contacts outside of an arbitrary “CPA circle.” That circle on the plotting board represented the “Closest Point of Approach”, or the shortest distance, that we were to allow between us and any other vessel. I’m guessing that the term probably means the same thing on today’s electronics.”  Still the same!
