I took down the radio panel and, with a multimeter in hand, was able to determine that the stereo wasn’t getting its 12 volts. When I improvised a 12-volt supply, it came to life. Progress, but a mystery remained behind the dead 12-volt supply line, which disappeared in the direction of the breaker panel.

After sitting next to Stan for about an hour, I stood up to stretch and get some blood flowing in my legs. As I did, I heard the faint but unmistakable snap of a circuit breaker going from the On to the Off position, followed by the sound of an alarm coming from the computer that was displaying the charts. “What happened to the GPS?” asked Stan as he looked at a message on the screen telling him that the GPS signal had been lost

Suppose you’re heading off on a two-day race and some of your crew haven’t sailed with you before. They come highly recommended, but they don’t know your boat or your standard operating procedures. What should you discuss with them as you head for the starting line?

​​​​​​​A problem can easily arise when several knowledgeable sailors are on deck during a passage or even a daysail and it is not clear who is charge. Each is partially attentive, but no one is paying attention to the details on the chart or what other boats are hidden under the jib but are on a collision course. Even couples on a passage can have this problem when both are on deck during the day.
