If you are looking for a method to stop spinning...
Use the hoist as on short haul. Means, after catching the rescuer/ rescue bag, climb up vertically with the whole ship+cable+rescuer. If you are out of obstacles go up to a few knots and start hoisting up. Same procedure on hoisting downwards. And try to use cable lengths greater than 20m.
You are right not to underestimate the spinning. Some operators use a "antispinning-line" from ground to rescue bag, but that needs ground forces, the right terrain and the right angle between rescue bag and ground troops.
Have rarely seen a spinning on short haul operations but really impressive spinning with hoists.
