Peggie's puzzle, and who's at the helm?
Many boats in coastal waters, and 99% of those at sea, are operated under autopilot. The rules require a WATCH. They do NOT require someone actively steering. That said, Peggie's puzzle is a puzzler. Initially, there is no doubt that the motor vessel was stand on, since both vessels were motoring, and the sailboat was to port in a crossing situation. Of course, it's perfectly legitimate for the burdened vessel to cross in front, if it can do so while the stand on vessel maintains course. Arguably, the sailboat became the stand on vessel when it turned off its motor and raised sail. Nonetheless, were there a collision and I the judge, I would allocate the blame to the sailboat. There are several reasons for this. First, the rules call for early and definite signs of intent. The sailboat violated this when it turned off its engine at the last moment to raise sail. Second, even if one accepts that the sailboat became the stand-on vessel, it is then required to maintain course, which it failed to do. Third, the crew on the sailboat clearly wasn't paying attention. And the rules require a watch. If the motorboat had continued to stand on, I would apportion some blame to them for not doing enough to avoid the collision, which is required of all vessels. Had it gone full reverse, that would have prevented the collision (as it did), or at least lessened the relative velocities of the vessels and thereby lessened the damage. OK, Peggie .. how'd I do? (And yes, I'm answering off the top of my head.)
