Next time you are in the simulator and the box ticking exercises are over ask the instructor if you can have a go at a simulated ditching - starting from 1000 ft and at night. Rate of descent no more than 200 fpm. VRef 40 (Boeing 737). All manual flying no autothrottle or FD.
Believe me it takes considerable instrument flying skill as you may not know exactly where the sea is. RA may not always be accurate in calm seas. Nor the barometric altitude depending on atmospheric pressure at your location. At no stage should you exceed 200 fpm and the nose attitude should be slightly nose high all the way down.
Guarantee you would go in like a dropped torpedo first time you try it in the simulator. Which is precisely why simulator practice is vital for this exercise.
