I'd like to see the result when that machine is airborne, and one wing dips and hits the water! The result would not be dissimilar to an aircraft doing the same thing, methinks - with equally disastrous results.
If you watch the Sky News link above, it does just that - with no ill effects.
I guess landing engine-out would be no problem as long as you keep the nose (prow?) up. Surprised to see that journalist passengering without so much as a safety belt - I guess it's like the old racing car philosophy; in an accident you're better off being "thrown clear"
