The engines on the 380 are spaced far apart, so the requirement for thrusters are very limited. I wouldn't add thrusters on that boat.
Having a person snagging and releasing a piling on command eliminates any need for thrusters under all conditions.
If I were to add thrusters then I would add hydraulic thrusters driven by a generator PTO. These would provide unlimited 100% duty cycle full-power output, with the generator running.
The very low-duty cycle electric thrusters are fine, but I don't see the need or utility when the engines and knowing the boat do so much better. The electric thruster requires a method to charge the 24V bank along w/ the existing 12V banks.
