This hardboat obviously has sufficient reasonably water tight bouyancy because she "pops" up again in the second set of pics. This is the advantage of a rib - unless you pop the tube - she will pop up again and keep on going. And assuming she is designed sensibly even if you do wreck the tubes the hull should remain afloat.
But plenty of people on here have "stuffed" the boat - perhaps not as spectacularly as this - but then there aren't many of us with 260 HP engines, and presumably this was travelling faster than the average rib?
