I'd like to know if a technology has been introduced to stabilize the,
"pendulum effect" occurence that leaves the rescue line swinging out of control ?
I have been winched into a dozen or so Sea Kings (and one Wessex??? it was many years ago!!) and watched dozens more from the wheel of a lifeboat sometimes stationary and sometimes doing up to 30 knots and have never witnessed a 'pendulum effect' on an empty or loaded rescue line - maybe just lucky!
More probably I just saw well trained SAR crews at work.
