Yes i really enjoy using the Sherpa too! She's a nice size vessel, not too small, and not over large. Ship Sim could do with a few more vessels of this size...esp Tankers! The large ships are a bit TOO large, (well i think but when i was at sea i only sailed on tankers from 75m LOA , 2500dwt, to 135m LOA, 20000dwt, so i am a bit biased!
)
