I believe what the player wants to know is whether a quest with the requirement to scout a province will be satisfied if you scout a "transport" on the continent map. It's been too long since I've been in a similar position to remember, but I believe a boat/ship/plane scouting doesn't meet the requirement. Or at least I think it didn't in the past but can't be sure, only way to check is to actually do it (you have to do that scouting anyway).
