I see from my logbook that as First Pilot I flew a night in-flight refuelling sortie in our ship's Wessex 3 and took fuel from "our" DLG in March 1972. I heartily agree that it was not a nice experience as the ship's manoeuvring resulted in a constantly shifting relative wind and resulting turbulence. One of those sorties which sticks in the mind!
Was the idea of HIFR designed into the Wessex 3 then? If so I would have thought that the IFTU would have tried it and that it would have been part of conversion training. I never connected the positioning of the the pressure refuelling point with that intention .... perhaps someone had tried and rejected the idea before .... and then some bright spark made us try it again in the 70's!
