Torque O D,
Re. 'winchman, the bloke still aboard' Yes I could have phrased it better as controller, but I think you get the idea...
BTW I'm sure most SAR people must be trained on this ( I've photographed from most things, fast jets to balloons & Jet Rangers but not SAR ) - sailing boats work by 'spilling wind', ie as they heel over the wind goes over the top of the sails, relieving centre of lateral effort pressure; a helo' works like a katabatic wind ( rotoring down not along ) and can blow a boat down - unless it's a dinghy it's not disastrous just awkward.
I've been sailing & instructing for 40 years - inc being a chief instructor for BAe, I would guess the instinctive reaction to that would be ' why didn't I drown them ' ?!
