Let’s face it. Many of us don’t make enough money to buy a super expensive yacht. But looking at cheap and expensive yachts can be quite fun. The Adastra Yacht can’t be classified as a cheap yacht. It will set you back $15m but offers speed, fuel economy, and luxury features. This yacht has a carbon fiber structure with a Nomex honeycomb core and a glass and kevlar foam sandwich hull. It also has a master bedroom with full bath and guest cabins. At 1150 hp, it is quite powerful too. Not a bad yacht to own for $15m.
