People have been using boats for fishing and travel for thousands of years now, and in 2016, many people still own and use boats, primarily for hobbies like fishing and sailing, or as vacation and party vessels. As with a lot of things in life, the larger the boat, the more expensive it tends to be, which is why most people have a generally small sized boat that does not require a huge upkeep cost. For the world’s wealthiest individuals though, upkeep cost is usually not an issue, which is why they have no problem dishing out loads of money for large, luxurious and incredibly expensive yachts. One such yacht belongs to former Google CEO Eric Schmidt, who paid around 72.3 million dollars for his vessel, which he promptly named The Oasis (pictured). This yacht in particular can house up to 19 people, and it comes with its own pool, helipad and gym, that can be converted into a disco.
