Day 12 anchored waiting for berth, just yesterday had the second officer "explain" to me that you can't do compass error calculations when the ship is anchored. When I asked him what the fuck he's talking about he said the ship needs to change positions and be moving... it was past midnight and I was tired so I just told him whatever you say dude and left. How do you even talk to someone who just has no idea what variation and deviation are?
