Actually Hog, all the RAAF SAR S76's are now autohover. What happens in the unlikely event that the system fails? Well that depends on the situation doesn't it; but if some poor bastard is swimming you go around and try again. What happens if your target is not stationary? Well, Hog, they rarely are. The system will handle a yacht at night in a storm, I know because I've done it. I've also used it some pretty nasty weather and it performed exceptionally well. My experience of is based on hundreds of hours of night over water in the S76 autohover and I'd be happy to go out in the thing in just about any conditions.
