If you've got $50 million to spare (and really, who doesn't?), you can get the Poseidon 180, a superyacht designed for Bugatti yachts.
The revolutionary Poseidon 180 Superyacht features the military developed Bentley Yachts' Air Cavity Hull, a innovative hull Design which offers reduced hydrodynamic drag for about 30% better fuel efficiency than conventional monohulls with unsurpassed seakeeping and stability in heavy seas, making sea sickness a thing of the past!
So if the gentle rocking of the sea won't make you sick, the knowledge that you just dropped $50 million should. As should the jar of Ebola I just threw at your face!
