The only other they thing can do is make sure the crew is well briefed about what happens when approached by pirates. Some shipping companies suggest the citadel affect: total lockdown. That is fine, but it doesn't necessarily stop a pirate from coming on board.
A ship should appear to be on an antipiracy watch. It needs to have some defenses, like a fire hose going outboard and, at night, halogen lights on the decks. The pirates might think there is another ship nearby that is not so alert and might be an easier target. It's a crapshoot. But you have to show you have some defenses.
Was your inspiration for your present career primarily due to your experience as a pirate victim?
Absolutely. I was as one who thought pirates were Blackbeard and Captain Kidd and Hollywood fantasy. But I found out these aren't swashbuckling rogues swinging through rigging, rescuing damsels in distress. This is a very serious and sometimes brutal crime.
I also get somewhat touchy when people say things like "Let's celebrate piracy and have 'Talk Like a Pirate Day.'" That, to a victim of piracy, is not something that goes down very well.
