While the money spent on this boat may seem like a waste or just plain extravagance, don't forget the many people who earned their living by building and maintaining this boat.
The money spent to build this boat was not burned or flushed, it went to the craftsmen, suppliers, designers, wholesalers, dock builders, shipyards and the companies that supply the materials.
Likewise, it costs a bundle to maintain and operate this boat (ship?). It is far better for the ultra wealthy to spent their money on mega yachts that just hoard the gold like Scrooge McDuck in his counting room!
We small boat owners do the same thing on a much smaller scale, by buying the boat, maintaining the boat, buying accessories, boat trailers, trailer tires, etc.
Keep your favorite boat dealer, equipment supplier, etc. in business----Buy something from them!
