get a crack in a hollow board and its going to sink.................
as compared to a heavy waterlogged polystyrene core forever?
logic tells me there would be some closed cell foam under your feet and that would provide enough enough bouyancy to prevent sinking.(If the board didnt have any skin bouyancy that is, eg HDfoam ,air(nomex core),Timber ,Bamboo or even Cork)
