Wow, what a nightmare for the tanker's crew, re; quarantine. I guess they have to isolate him in a cabin and go through a whole bunch of hassles to keep him fed, etc.
Another captain may not have wanted to bring a typhoid Mary aboard his ship these days. I'd count this guy extremely lucky. I wonder if the whole problem began because he didn't close the companionway hatch when the weather kicked up a bit?
This is a prime example of why going sailing is not a good idea in this pandemic. Any mistake or breakdown could lead to someone contracting the disease. There are plenty of non-symptomatic, untested carriers out there. Anybody you meet could be one. Or, you could be one!
Did anybody read where the ship was heading? If this guy isn't a citizen of the country the ship is going to dock in, he could be refused entry and the ship will have to keep him aboard until a method of repatriating this guy becomes available, or they take him home. With few planes flying, that could be quite some time. In the '80s, when I was running freighters, if we picked up Cuban or Haitian raft/boat people on the way back to Fla, we were required to repatriate them as they were not allowed to land in the US. This cost the companies beaucoup dollars and they really didn't appreciate it at all. Kinda put the captain between a rock and a hard spot. Do the right thing and either lose your job, or pay the costs out of your own pocket. Rich ship owners suck!
