After doing that it makes fender recovery seem a pointless farce. Its no more testing than motoring up to a mooring buoy, in fact that's usually more challenging in a river current. Probably one of those things (like the jack stay up the side deck) that gives a false sense of security, making people think they have ticked the box, then when it comes to it its really not up to the job.Try out your solution with a 100kg life-size dummy.
I guess 2 person sailing, unconscious MOB, its really only likely if you can launch a tender to get level with the casualty to attach them. Less agile person anyway. A fit person could dive in with 2 ropes and get back up the ladder.
