While people are blaming sailor lousiness and training, I have to ask why humans are even controlling these ships? For all non-war maneuvers shouldn't these ships be self-sailing? Don't these high tech ships have basic obstacle detection? People should be blaming technology (or lack thereof) onboard these ships. There should be "sail-by-wire" equivalent on ship where humans with their limited sensory inputs and computational capability are only allowed to provide relatively high level goals. Ships computer should be able to deal with obstacles and remaining within safety parameters. I'm sure they have this system but it just didn't worked as expected and that should be the core of the problem.
