In my experience, the RN didn't believe they needed weather limits (or any others for that matter) because they felt so superior to the RAF and told everyone could always get the job done.
That explains the myriad of dits detailing close calls, almost mid-airs, just getting in by the skin of their teeth and, btw, quite a few actual accidents.
I was at a training ground near Peterborough one day in fog, with all the training tasking cancelled and then a Navy Wessex appeared over the fence having hover taxied for miles to get there - FOR A TRAINING EXERCISE.
Nuff said about attitude.
