I'm fairly sure the max wind speed for rotor engagement on the S-76s I flew (A, A++, B, C, C+, about 4,400 hours in total) wasn't as high as 60 kts.
Yes, I was being polite
It was certainly 60 knots for operating on a deck with an enroute wind of 75.
That was post G-TIGH/Cormorant A, prior to that 75 kts on the deck was allowed. I recall flying nearly 3 hours to the Murchison and the windspeed was gradually increasing. As we got final clearance we were told the wind was 80 kts and my crusty old captain said "what's 5 knots, we're here now?" We'd parked a few degrees out of wind to give a few degrees of tilt to maximize the gravity refuel, so initially I was in the lee, and as I walked around the baggage bay I walked into the full force of the wind and my zipneck suit immediately inflated and I became airborne heading towards the Tail Rotor and the deck edge. Bunching into a ball got me back on deck and then I clambered with the net to the sponson and clung on. I learned about wind from that!
