If you have an old ship:
1. You spend money first on maintaining the operation of the equipment as it exists.
2. If you want to spend more, you can put sensors on critical data acquisition points.
3. If you want to spend even more, you can automate critical systems in the boat.
I’ll go out on limb and say this ship is in phase 1. It floats, but they couldn’t even keep the engines running.
Of course the crew has internet, GPS, and tablets aboard. No one operates without that stuff these days.
But with this ship, I would guess that “hacking into it” means that you might see the videos the crew watched, and that’s about it.
Contaminated fuel could have been the problem. Apparently that’s a known issue in the maritime industry, particularly if the fuel originated from China.
Somehow it has to be explained how the ship miraculously turned the last minute and hit a vulnerable part of the bridge.
