Those wanting to criticise twin engines (often pilots with little or no experience of operating them) often fail to recognise that no-one makes a single engine big enough to do the job, so as far as the pilot is concerned, there is no choice in any case.
Having operated the S-76 for some years, and afew thousand hours, I'd agree most strongly that some variants are far from "blessed" in the power reserve department unless the weight is kept right down.
If the aircraft couldn't be operated to Class A performance standards then a ditching is a likely option and in this case, no lives were lost.
BTW, the title and initial responses on this thread makes it appear that some think an airframe is more important than the lives of those within it.....
