I honestly don't think he has one. Suicide wouldn't be a hobby if it were that easy. I get the feeling he's some kind of martial arts user. I also get the feeling Shanks might have a fruit. We've only seen him block one attack, so we know next to nothing about his non-haki abilities. I remember people thought Whitebeard didn't have a fruit, but then he surprised us all. I think Shanks will be the same. I can't really think of any fruit that could break the swimming rule and still be plausible.
