Keeping Watch at Night ?

[wkstar]

With AIS, Radar, Sonar, AutoPilot etc
With One or Two people onboard do people just lower the sails and go to sleep
Or do people still do 3 hours watch ?

It seems to me that if the sails are low and you are not in the middle of a shipping channel. Then you should be able to get some sleep

With the gear I mentioned above a LOUD Alarm should go off if something were to approach the boat?
I am not saying take your Valium , Rum & zonk out for 10 hours.
Youtube makes it seem That going on a passage is a 20+ day prisoner of war No sleep torture test

Sailing is suppose to be relaxing, but with no sleep after a few days , I would get a bit cranky
