What is the power plant like in something like this?
Two CAT engines at 2760HP each. Two 105 KVA Kohler Generators. Seamless transfer, load shedding, so you never notice going from Generator to Shorepower, (resetting clocks, and TV's is a hassle.)

200amp 380VAC/208VAC, with an 100KVA Atlas Transformers (2). Each weighs around 1400 pounds.
Transatlantic capability at 15 knots, Dive Compressors,2 Hot Tubs, Commercial Grade Galley, Crews Qtrs, with their own galley. Two Satellite TV systems, 1 for Europe, 1 for the rest of the world, 2 Watermakers, 17' Tender in the aft "garage", 3 Davits (cranes for the 6-pack of jet-skis). Sky Lounge, one hell of a Nav computer, Sat Phones, terabyte video library, wi-fi, of course bidet's, and all the bells and whistles. Adding a sushi bar and owners gym.
It costs $38,500-$50,000 to fill with fuel.
and of course Simon, which also monitors watertight doors, the alarm system for all entry doors, and video monitoring, and can get grouchy at times.

You DO know where Simon "Kill" switch is I hope. 
ABSOLUTELY!!!!! Take him out faster than a head shot with a 50BMG!
Even his "back up" power supply....
