Honestly, no. This one time I was pissed off at Egypt for undercutting me in cotton prices, so I tried to set up a blockade to prevent merchant ships going in and out of Cairo.

... and it would have worked, too, except for my naval vessels were all CSS classes. I even tried to name them cleverly, a la "USS hero unit" or "USS datatable table-consensed span9", but my plan was foiled.
