I did like the scenes in the last A&E Hornblower series where the French and English frigrates were searching each other out in the fog. No radar, no GPS, just blundering about listening, then suddenly a ship materializes and they're both firing away like mad! Reminds me of the time we were slowly nosing our way through Penebscot Bay in the fog a few years back. There we were in a forty-foot ketch banging pots and pans trying to avoid the tourist cruise boats and the occasional oil barge. If we'd only had Brett's cannon!
