There’s a saying:
“The only difference between men and boys is the size of their toys.”
A few tech moguls have some very big, floating toys. Mark Cuban, Larry Ellison, and Paul Allen are just a few who own some of the largest yachts in the world.
Others vacation on yachts with models. Others zip around with friends.

Jack Dorsey doesn't have a yacht (yet), but he was spotted vacationing over the winter holidays on one.
At the end of December, Jack Dorsey's photo was slapped in The Daily Mail aboard a yacht in St. Barts. Dorsey is the co-founder of Twitter and CEO of Square.
The papparazzi didn't know who Dorsey was; they were after bikini pictures of the model he was with, Lily Cole, who nearly lost her top in the waves. Dorsey was dubbed the lucky 'mystery man' alongside her.
Larry Ellison formerly owned a portion of the world's 8th largest yacht, The Rising Sun. Now he just owns an America's Cup racing team boat and another yacht.
Among the multiple mansions and island he owns, Larry Ellison owns an America's Cup racing team boat.
