Re: Sailing Singled Handed & No Watch at Achor
AIS alert might be the best ida. I've seen dayliners heading from Florida to the Bahamas with NO ONE on the bridge, so it won't matter if they can see y0u on the radar, they're just not keeping watch. You can be certain that some commercial traffic is not keeping watch, or the watch is asleep, so it is up to you.
At least if they are transmitting AIS and you've got an alarm set for traffic on a collision course, you've got some chance.
When it is too deep to anchor, you can deploy a sea anchor or drogue. Do remember that if you have insurance, it probably is null and void while you are single-handing offshore.
