Recently did my first beer can. The course called for the start line to be WS. I assumed this to mean the mark W sould be on the starboard side of the boat. We were the closest boat to the mark as we approached it and the Committee boat radioed to tell us that we were approaching the mark on the wrong side. I can only assume that from the committee boats position, it appeared that we were going to pass with the mark on Port. Of course, this totally screwed up what would have been a great start (dumb luck) because we were suddenly distracted, trying to figure out what they were talking about. Was my assumption correct?
