Trevor,
I didn't say there was a break in any routine at the beginning or end of the
day.The logs start at noon one day and end at noon the next day while
underway or in port.While underway the ships I work on stand either 4 hrs
on,4 hrs off or 6 hrs on,6 hrs off continuesly as set by the master(on the
Station Bill).Watches while in port have a differant schedule(8 on,8 off or
12 on,12 off).So as examples,say I have the 1st 1200 to 1800 watch
01-01-03.I have from 1800 to 0000 off 01-01-03.At 0000 to 0600 01-02-03 I
report back for watch continuesly.If I have the 1st 1200 to 1600 01-01-03
watch I have from 1600 to 2000 01-01-03 off,report for the 2000 to 0000
01-01-03 watch,have off 0000 to 0400 01-02-03 and report back for watch 0400
to 0800 01-02-03 continuesly.
All the ships' logs are kept on a noon to noon schedule is what I wanted to
convey by the ships' day.

That is interesting, Doug!

Can you explain in what ways the ship's day ends at noon? The ships I
have worked on (mostly government research trawlers, some commercial
fishing boats) had no break in their routines at noon. Indeed, aboard
Australia's "Soela", we used to work 8-hour watches with one running
0800 to 1600, so there was literally no break at noon.

Do you think of your ship's days in terms of calendar dates or just as
units of working time that span across two calendar days? If you do put
dates on noon-to-noon days, do you use a date 12 hours ahead of, of 12
hours behind, the civil calendar?
