zelda wind walker question...

Archived from groups: rec.games.video.nintendo (More info?)

With this game, are there quests or tasks that can only be completed for a
certain portion of the game? I'd like to be sure I can go back and dot all
my i's later on.

For example, there was a sailor on the island with the village on it that
wanted me to change the wind direction. Now that I can do it, I can't find
him anymore.
