It is not a stupid question
I think it depends on which Hero character you are playing, and also on what traits your Hero has. For example, my Knight has the traits Adventurous and Whale Ate My Parents (which is hilariously funny by the way!). The Adventurous trait allows him to "Go on an Adventure" when I click on the ship. The Whale Ate My Parents trait allows him to go on a whale hunt when I click the ship and "Scream at the Sea" when clicking on the dock.
Beyond that I think that certain quests will involve doing things at the dock, although I haven't come across any yet. Personally I have found it a good area of the kingdom to fish and find different metals/gems and plants.
I did also notice that in the village market you can purchase maps to far off islands - does anyone know if purchasing these maps will give you additional interactions with the docks/ship?
