I have been told roll her over to the right in an anti-clockwise machine so that the reaction from the blades impacting the water sends the tranny & engine backwards away from you.
I agree
I have seen a machine where a M/R strike on the retreating blade (ground strike) put a dent in the pilots head from the xmon severe enough to put him out of flying forever. (the pilot had a helmet on, but to no avail)
I am surprised at Nick's statement.
In Mechanics every action has an equal and opposite reaction.
When hitting the ground , or the water, think;
1. Do you have lots of energy on the M/R system? How can I use that to my advantage, (if it is necessary) especially to dissipate damaging velocity?
2 Answer. After disspating the downward velocity, (only if into water) then roll the advancing blade into the oncoming obstacle.
3. The items which it is connected to, I.E. the xmon must tear backward away from the cabin occupants. Have seen that many times.
Above all, THINK. Energy is stored in the rotor sytem while it is rotating.
Think about how you can use it to help yourself.
Water strikes tear airframes apart like you wouldn't believe.
Tearing of airframes is better to be used for time (and energy disspation) to get out from under water.
