5.5 million per year would be 70 crew members wages? A small-medium organization. Wiki -"The United States Navy has nearly 500,000 personnel" No food costs. No one gets evacked cause their toe got infected. No crew quarters, toilets, mess on a ship = a pretty cheap ship. Can roll over in a storm. No re-stocking food, although fuel needs might make that redundant. Less time at port, perhaps, equals a bigger ROI. I guess normal ships are not cheap.
