It would be nice to have a title unlocked after rowing for a certain amount of nautical miles.
Or titles linked to the trading companies, BUT for selling items never placed on a ship, only on rowboats (or swimming if you are brave enough).
for example
♦ Tireless smuggler - for selling 100 merchants items
♦ Ferryman of souls - for selling 100 skulls
♦ Unsinkable gold bearer - for selling 100 items to the gold hoarders
