a bit related to that story, I knew someone that worked at a jet
boat tourist attraction and they told me that one day a
captain had a full
boat (57 people give or take) and accidently drove the boat over some rocks due to drop in
water levels, putting a hole in the bottom of the boat while in the rapids. nobody was hurt as these
boats are designed to withstand such damage and still be able to float and drive back to the docks, but i bet the passengers were all thinking "why did i sign that waiver" when it happened
