Historical info:

Signal cannons were used by ships coming into harbor, which would signal the authorities in the port to come and inspect the ship before it offloaded goods and crew.

 Thunder mugs were especially useful during the time of the black plague, when incoming ships had to be screened for the disease before crew could go ashore.
