Sleeping Patterns for Live-Aboards?

[Pelagic]

I am curious whether other sailors who have lived aboard for long periods of their lives have adjusted to daily sleeping patterns that are similar to mine? (Of course different when watch keeping on a passage)

Awake 5 or 6am, then if I can,

Sleep 2 till to 5pm,

Awake 5 to 9pm,

Sleep 9 to Midnight,

Awake Midnight till about 2- 3am, then sleep again till 5 or 6am.

Not sure how I got into this pattern as I have been doing it ever since going to sea, taking naps in the afternoon when generally everything is organized and being up after midnight to check lines or anchor, weather, security watch changes and enjoying the quiet time to do my accounting or correspondence.

I don’t know if this is a healthy or unhealthy pattern but the funny thing is after retiring from being a professional captain I still have this same sleeping habit whether I am living on or off my boat and with just the 2 of us.

Did you find yourself changing when you slept………. after moving on board?
