Did Ben Lecomte really swim across the Atlantic ocean?

Yes, I also remember reading that in the news. Whether he "really" did swim the Atlantic or not depends on your interpretation. He was accompanied by a support vessel and obviously had to spend time eating and resting. So the vessel was not stationary at those times. IMO, he swam/rode across the ocean, but it was still an amazing feat. I'm certainly not up for it myself lol.
