There is a DR400/180 with long range tanks which ran out of fuel and ditched in a Norwegian fiord. They jettisoned the canopy then realised she was floating so sat on the back with feet dangling in the water. A fishing boat came by and the two climbed aboard having only got their feet wet. The fishing boat put a rope round the prop and towed it to a nearby harbour and it was dragged out after 2 hours and eventually flew again. I know all this because I almost purchased it 20 year later and the story came out when we looked at the logs etc.
