Re: Sleeping While at Sea
We only use AIS, have a transceiver which I very much recommend over just a receiver. We have seen freighters on a collision course alter their course 10 miles away and then go back to previous course after passing. We pretty much rely on eyeballs. The closest we have come to a collision was at noon on a bright sunny day off coast of Ecuador. The crew of a very large container ship obviously was not looking at radar, AIS, or outside. Call on the VHF got his attention pretty quick.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
