so just reading off chart in notepad, I got the following: July 2, 1943 - new moon 12:44 ; July 10, 1943 - f-quarter 16:29. (I figured this is saying, over the 8 days, the moon goes from new moon to f-quarter, starting at 12:44 and ending at 16:29. but then, the game only has four phases.)

then pulled out for july 2nd and 3rd:
2- mr: 05:00, ms: 19:03, sr: 05:02, ss: 19:05
3- mr: 05:49, ms: 19:49, sr: 05:03, ss: 19:05
( oops, I was actually looking at "setting" f-quarter moon)

now the fun part: sub is approximately at 140.5w. add in the 7.5 offset, then (180-148 = 32 and divide by 15 = 2.133 or 2:08 hours. then added in offset hour(?), to get a 3:08 correction. which becomes -
2- mr: 0808, ms: 22:57, sr: 08:10, ss: 22:13

loaded game and sun is totally set by 22:43. moon will not be far behind.
So is sun/moon rise when it first peeks out or fully up? is setting when starting or totally behind horizon?

however, now, moon is 'half full'. saved at radar contact to go to lunch. reloading game, it is still at 'half full. (why?) is math correct for hourly correction? I think this is still very usable for planning and thank you for bringing it up


thinking about it, I save often, so i'll go back to july 1 and see if it is a new moon.

If you're at approx 140d, you are roughly -4 hours if Pearl is your home port. The clock in your boat is home port, Pearl base time and you need to calculate from Pearl 'base time'.

The 180d is not base time unless you're sailing out of Midway. In Pacflt I always sail out of Pearl.

Did I misunderstand your situation? What is your home port?
