I tried raiding this one port on the coast of Africa, I forget the name, but there wasn't a daggone thing in there so I left. 30 minutes later, ahead flank and 1024x normal speed, I get stomped on and sunk by a destroyer.
Just goes to show you, if it's safe nearby it isn't necessarily safe to let it get to your head, it just might rear up and bite you where it counts
