I was referring to unintentional calm water touchdowns. Japan a long time ago and Lake Victoria are the only examples I can think of. Prior to that, the only real ditchings I can remember were the PanAm Stratocruisers between the US West Coast and Hawaii, a looong time ago.
The only intentional ditching that comes to mind is the Ethiopian 767 a few years ago. No power, thinking "keep close to the beach" so there's a chance for people to swim for it, trying to follow the swell line. And finally having port pod digging in if that was what really happened, then the wing, then that awful cartwheel. In circumstances like that I doubt whether a 4-engine aircraft could have come off any better.
