To give you an idea of the way one rule works, consider this scenario: You’re a few miles from the inlet on the way in from a fishing trip. Another boat is on its way out, closing quickly on a course that would meet you head on. Time to change course. According to the Rules of the Road, both vessels should immediately alter course to starboard to avoid a collision. So you dutifully comply. Yet, the other vessel turns to his port – toward you. Yikes! What now?
