content: I don't think humans are much of a deterrence for hijacking. I was recently reading about the class of vessels that the new Ben Franklin tanker falls into. These things are ridiculously huge. They're 400 meters across, 60 meters up. Stacked end-to-end the ship's cargo containers would stretch near 60 miles. They're crewed by about 20 people. I'd think if anything they'd be a liability as they can become hostages and in any case where military or other armed forces get involved, the pirates would always have a major chip in play. I'd also argue getting humans out of the picture opens up the door to far more effective deterrence measures. With no need to provide access or habitation for humans on board even just the first level deterrence could be far more effective. Wrap everything in an air tight ultra thick shell, as the images on the page seems to indicate they're doing along with an ultra slippery polymer of whatever sort. I mean most of the pirates aren't exactly paramilitary forces - they're a half dozen guys in a skiff with some big fucking guns. Scary against a traditional ship, not so much against something like this.
