And yet TRO3086Supp. says
I didn't say "Wouldn't have any" I said there wouldn't be MUCH. of course they're going to have SOME. Now, as to whether they brought a whole bunch of them (Plus the tooling to make more) with them on Exodus? depends more on whether or not the line developer gets really "Into" wet-naval warfare as a 'thing' (because the Clans always have to have the best of every class, even when it makes zero sense or requires a rules revamp for them to get it. it's a rule just like "you roll dice for initiative".)
more than likely you might see one to four of them even GOING on exodus, and that's as survey equipment. (assuming Kerensky actually put thought into the idea of establishing his colonies rather than everyone starving to death in interstellar space.)
but it's vanishingly unlikely that the Clans would have a luftenberg-equivalent, or some of the larger wet-naval assets that the Davions like to use in heavy rotation, not when it's more 'efficient' to keep colonists near easily-obtained mineral deposits and fertile regions close to shore. (particularly, easier to control your lower castes by limiting their movement to areas that favor your dominant unit types.)
Highly-centralized economies with strict caste systems don't tend to invest in situations where that control is put at risk-and an archipelago surrounded by deep water is easier to patrol with WiGE vehicles, than to control with v-hulls or catamarans, because the WiGE vehicles will be faster than anything they might be sent after, aren't hampered by dirt, sand bars, or submerged rocks, and can cover a larger area with fewer bodies more efficiently.
Further, they might even CALL such vessels "Cutters" because that's the ROLE they play. a fast, below-frigate littoral vessel for customs enforcement, close-to-shore search and rescue, and coastal law enforcement missions.
this isn't to say subs aren't present-they likely are, but large ones are going to be most likely absent, just on account of most Clan worlds have shallow (at best) seas, rather than extensive coverings of deep water, and most Clan facilities will be near the shore (for efficiency's sake).
