Playing around on Dartmoor does not qualify you for Littoral ops,
No, but when you consider that 702/824 spend the majority of their Flying training within 15 miles of the coast then I would argue that the RN Lynx / Merlin fleet are pretty good at Littoral ops. In fact, I'd argue that they were the UK military experts at it.
