Hi guys. Complete novice to the world of ships and yachts, but here to learn. Was just looking at random yacht listings when I noticed that many cruise ships and ferries and cargo boats actually cost less than yachts 1/3 the size. For example 1980 CRUISE SHIP, 528 PASSENGERS Power Boat For Sale Several more around the same price level and there was one older one that went for like 5 million, and another that was literally around 2 million. My question is: fuel efficiency problems aside, why the huge price discrepancy? Obviously those large ships were used but the price discrepancy between them and similarly aged yachts is still massive. Does this imply that a new 150 foot yacht costs more than a new 500 foot cruise ship? Why can't a yacht builder just make the hull of a cruise ship/ferry/cargo ship with yacht amenities? I would imagine that would be no more expensive than making and furnishing separate living quarters for 3000 people. And if they can, why don't they? Who wouldn't want a floating city to be their yacht? I'd imagine there would at least be a decent market for this. Thanks to everyone who is willing to entertain this absurd question.
