I think a cruise ship will wind up being the next 9-11. Think about it, its so easy and a good test case was already done when they bombed the USS Cole.
Imagine two fishing trawlers, one with 5K kilo's of explosives and the other with gunmen. They can leave from any port in the world and travel unchalleneged to their target. Bomb boat explodes, mega cruise ship sinks in less that 15 minutes, gunmen with AK's to clean up everyone else. Total atackers less then 19 men and a death toll of many thousand, well eclipsing 9-11.
The sound generator and even heavy weapons wouldn't do you much good since you would probably not understand whats going on until its too late, and we cant have a destoyer follow every cruiseship wherever it goes.
Interesting. I hope the FBI, etc. are considering that possibility.
Disagree. Those ships have pretty decent surface radar, they will see any "visitors" coming. Then it's on the radio to call out the calvary, if any Navy has ships or aircraft nearby. Failing that, and most of the time it would, you get on the hailing frequency and warn them off. Then you start shooting, shots across the bow if you feel you can safely do that. Then sink the SoBs, before they can get into RPG or bomb range. If you're lucky you set off their main charge when they're a thousand yards or so off.
I concur. It would be easy for some tub filled with amonium nitrate to ram a cruise ship.
Plus, all the explosives would never pass through customs --- not yet in port.
