Im fairly new to the whole airship/submarine system. I have heard of mixing of airship components, but i have little knowledge on the value of stats. So at least until now i have been satisfied with unlocking the new zones and listening for new info on what is from which zone. Im running a full shark and a full whale. Looking at stats in hindsight the shark seems like a good scout with its high surveillance and whale should be able to bring back big quantities with its high range and retrieval. Until we figure out the range requirements we have, it might be good to spam the new areas with shark and hope for huge hauls of choice loot with whale.
