A while back I was motoring into a Scottish port. I was unsure of the approach, and came in too close to the shore... my fault. As I arrived, the harbour master said "I was just about to call the coastguard, you went right over that rock" (a local, and well-known, ship-sinker).
I asked why he did not attempt to call me first. I got no answer, just another smile.
That I gave it a very wide berth in future was not the only lesson learned.
It's a game to some of these port people there guys... a game, and jolly entertaining too it seems.
