I don't really have all of the details. I was just listening on the radio. Here in Milwaukee we have a high speed ferry that crosses Lake Michigan a few times a day. In order to get out of the Milwaukee harbor it goes through one of the smaller cuts in the seawall near it's berth. When it leaves they announce on the radio and blast the horn. However, today there was a sail race going on that, as part of the course, went through the same cut the ferry goes through, producing a long line of sailboats. The wind was blowing 20-25kt. The ferry captain hailed any and all sailboats... no answer. He had to keep the boat in place for about 15 min while the race passed. Because he had somewhat limited mobility, would he be the stand-on vessel? Would you heave-to, and let him pass during a race? Just wondering.
