Barack Obama Goes Kitesurfing With Richard Branson

Barack Obama is solidifying his "coolest president ever" title ... because he now knows how to kitesurf, thanks to Sir Richard Branson.

Before the Obamas jetted out of Necker Island last week ... Barry made sure to get his feet wet with the extreme water sport. Meanwhile, Richard did some foilboarding.

Then they went mano-a-mano! And you gotta see how it ended.
