whats a good watch schedule?
I don''t know how either of these will apply to your situation, but...
On a trip from Cape May to Rhode Island earlier this summer, we had two watches of two people each (plus the captain/navigator who was not on rotation) standing 6 hours watches during the day and 4 hour watches at night.
On a longer trip to Newfoundland last year, we had three watchstanders plus a cook. With the three of us, we had a watch schedule of 4 hours on, 5 hours off. The first and last hour of your watch were overlapped with the guy before you or the guy coming after you; the middle two hours of your watch, you were on watch alone. For the return trip, we switched the order of rotation, but kept the same pattern. It worked pretty well.
