Naval combat also works better with the I:R map due to the greatly increased detail. The CK2 map doesn't really have the scale to properly model galleys having a short range and needing to stay within a reasonable distance of fresh water supplies. Usually it's just 1-2 sea zones distance. In I:R you have a great amount of detail with coastal waters and archipelagos:

In other ways galleys have advantages near the coast because they are independent of the wind and can more easily get close to the coast (and sail configurations for sailing ships were still pretty primitive). That made them attractive for coastal defense or amphibious invasions. Even in the north. Or to carry trade goods along the coast. A galley could cross the English channel in good weather, but you wouldn't invade Norway from England with a galley fleet. You'd need very complex systems to reflect stuff like that
