Spot4 - are you sure about the RN not needing single pilot skills?
AFAIK the only guaranteed two-pilot rotary aircraft in the FAA are the baggers and the SAR cabs.
Junglies SK4, Merlin Mk 1 and Lynx are all single-pilot.
847 Lynx can be single pilot plus obs or two pilot, and I think the five SK6 used by CHF are also two pilot?
