IIRC, the standard RN cat stroke was 100ft/1second: Ark's two cats were 180ft and 200ft, so about 2 seconds was right. The Melbourne cat certainly looks a tad shorter, I'd be interested to know just what length it was?
I only scored a night back seat ride in a Gannet AEW3 off the Ark, it seemed quite sedate after catching the wire. Nearly woke me up

All this talk reminds me how much better it is to stop, then land, when recovering on a Grey Funnel Liner
