I love some newbee questions. I never know if the person is serious or not!
Is it safe to leave the controls? Or is sleeping while moving akin to taking a shower while driving an RV?
I like the RV annalogy!
yes, a modern boat is like an RV. The Cruise
Control also has a guidence computer.
So on a long haul you just set the computer and sit back and watch the scenry.
The person who is on watch has (for us) a 20 minute timer. They do their watch and make sure the navigation
is correct - currents or wind
changes may stuff things up. But also there is plenty of time to make coffee, a meal, read a book etc. We just make sure we pop the head
up every 20 minutes.
On some of our longer passages we have not seen another vessel for 2 weeks!
