Moreso a random arbitrary number I picked out. If we assume 6 seas and apply 100 galleons to each sea (which is arguably low if cargo scales off of travel distance) then that’s 600 total. Which for traveling 6 seas is honestly a good chunk of change, depending on the storage of each ship then that’d be a good way to make bank later on in exchange for 50 galleons.
Honestly though this + this would be good for a cross sea economy with cargo. Perhaps some stuff can be considered high demand and draw more attention from pirates, adding more risk but it’d be worth the big bucks.
