11. Richard Branson: Submarine
Founder of the Virgin Group, Branson has a net worth of $5 billion. Since he owns a 74-acre island in the Caribbean, it’s only right he also owns a few high-priced ocean toys. In addition to his famous yacht, the Necker Belle, Branson also owns one of the most interesting toys on the list: a submarine. The billionaire’s guests can enjoy an undersea adventure on the ridiculously awesome Necker Nymph.
