The lifeboat/helicopter remain the same, New technology means if we are in distress he communications systems, DSC, AIS, plotters which give us a lat/lon are all things which remove the human element from getting the whole rescue started. It aids everyone to be far more efficient. There was never an intention to diminish the human element by those that actually enact the rescue at the chalk face
My mistake to muddy the waters with the MCA closures, Please ignore the comment
Anyway back to the actual thread - There will be those that agree that when water temperature is 10 deg or below then 'suitable drysuit, immersion suitor other suitable clothing should be aboard the boat
There are others that disagree with the 10 degree suggested ruling on grounds that MCA have not provided any evidence to suggest that abandonment to water is as frequent in small comercial vessels. Many commercial operators believe abandonment to liferaft is a better alternative. I just happen to fall into the latter camp.
