Being armed in international waters is one thing. The instant that a ship goes into port, the crew is subject to the local laws. It would be a nightmare for the company to coordinate this in the few countries that would permit it and most would just prohibit the weapon possession.
I can tell you, first hand, that going to "friendly" countries with weapons even with official and diplomatic passports can be problematic... now for a ship crew to do it. I don't think so!
I think the law part is fairly easy. There are numerous internationally accepted laws being broken. You may, however, run into more problems deciding the punichment (based on which country you ask).
