may I suggest the updated RAM launcher?

are you certain these vessels are painted that dark, btw? on pictures they seem to be lighter, but that might be the light.
there might also be some more difference between shape and colour on the air intakes behind the crane and behind the RHIB, and would there be no railing at all on the midships part?
other then that, looking very nice! (wow that propeller looks vulnerable over there)
