I am playing a self-imposed "single-city challenge" game (i.e. a game where I restrict myself to having only one city). Naturally, I built the city beside a sea to be able access to the rest of the world by ship. Unfortunately, I built my city in what turned out to be a landlocked sea (a large lake). As a result, the ships I currently have are not able to go to the open seas.
I am now considering bribing the ships (trireme, caravel, or transport) of other players to gain access to the open seas, but how can I bribe the ships of other players?
