Shorts skab

Previously I sailed with two other people and we did watches of 3 hours which gives you 6 hours off and it was very pleasant. You get enough sleep and your shifts rotate, so no one gets stuck freezing every night. My husband and I are about to do a 4-5 day sail on our own, and I want to know, what is your favourite watch schedule for 2 people? We're planning on 4 hours on, 4 hours off, unless you convince us otherwise! Also, would you do a different style of watches for 3 people crossing the Atlantic ocean? Please comment. What are your thoughts, sailing questions, sailing watches, sailing schedules, how do people sail, what is the best sailing schedule, what is the best watch schedule, what do you think, experienced sailors might know, everyone has an opinion, tell me what you know, tell me what you think, asking honest questions, how do you cross an ocean
