Gomer SASless, SL etc....
Ignoring deck size restrictions, why can't "deck hopping, rat killing 200 landings or you're a pussy" shuttles be done with a 212, 412, or any twin?
In the 80s, on the Southern North Sea, over 75 landings per day was the norm for an S61 and that included some longer transit legs. All close together platforms and double that would have been possible.
I'm not sure I see the issue here. Silly me!!
