Perhaps... in the far, far, far, far future [read that as NOT soon] there might be a land that you must cross a significant amount of water to reach [like a Nolthrir city?]... making a need for boating or long distance-flying of sorts. Of course, there's no reason the pterosaurs wouldn't be able to cover that, but it might be interesting to see an in game reason for rowing. Since, rowing as a sport would not have been prudent given the historical settings, imo.
