^^ I wouldn't have expected him to get around like that from a sitting position -- and he's 3/4 of the way around before he got below the board (i.e., he could have done that from a 1m board). That guy is surprisingly nimble considering his size/shape -- I don't see how this is gonna hurt though (maybe the board )
BTW.. 3 meter boards have become almost extinct at swimming pools. The owner of the pool I go to said he had to pull his out because no one would insure him except Lloyds of London. I have seen a few still around, so I expect he was exaggerating the point: "insurance was just too expensive."
