I was sailing 2nd mate on a container ship standing the 00-04 / 12-16 watch. I was getting up at the usual 1120 hrs call, having lunch then going on watch.
The Chief mate told me that if I wanted to sail c/m I should instead get up early because during the day is when most of the work/planning/discussions takes place.
I changed my routine; got up at 0900 hrs., worked until lunch and then went on watch.
I got most of my sleep after 1600 hrs., I’d have a light supper and then get some sleep. This way the social / recreation time is missed but working when the C/M, C/E and Captain are working.
I felt like shit during the day but the 12-16 is during daylight and more going on. However I did feel more rested on the night watch, felt better, 00-04 went by faster
