Cruising is not like a race
crew system not just because of numbers, but also the need to spend some time together.
We agreed our shared time was a minimum of 1800 to 2000 for drinkies, evening meals
prepped and eaten, engines run to charge batteries, watermaker
run. Day time a minimum of 0900 to 1000.
Between then it was me down 2000 to 0100.
Sue down 0100 to 0600.
Me down 0600 to 0900.
Breakfast together 0900 to 1000 and engine
run if needed.
Then flexible day shift usually 2 or 3 hours on and off. Lots of time we were both up.
That style of watch system may not work for others but worked really good for us - which is what I think really matters.
