@TomAndreas-NOR:
Iīm with you, survival equipment is essential, prolonged flight over water in a single engine helicopter should be avoided whatever the outcome to this investigation, but people will speculate and things will get confused and messed up.
I firmly believe that the BFU will publish their findings as soon as they can, that these findings will be correct and that those who act responsibly will take correct actions with regards to flight over water anyway (like @SASless said).
Until then, be sure that the SAR boys and girls are there to look for you potential customers who like to push it.
The only thing that worries me is that most passengers will not have the insight that we have and therefor cannot distinguish between a responsible pilot and a risk-taker.
Thatīs were rules and regulations come into play and need to be amended if deemed necessary.
