SARREMF
I have to wonder where you got your ideas from when you decided to correct Crab. I have no experience with the EH101, but I have had time on the USCG HH60 fleet, and I can tell you it is a significantly worse winching platform than the Sea King/H3 because of hi rotor loading. And it certainly gave us more downwash problems in urban areas and beside other aircraft than the Sea King. I can only imagine that the EH101 at 20 to 30% heavier would be much worse.
As for your EH101 "doughtnut" theory. I'm new to this forum, but that comment makes me wonder if you have ever actually done any SAR work. Exactly how would you get all of a small boat into the doughnut without blowing it all over the place as you moved in? And where would the "doughnut" be in a standard 15kt wind day at sea? Presumably not directly under the aircraft.
