Well jeah, people are out on the seas busy with their farm galleons to collect the production of their outposts. They even don't need to stop for tames and they don't need to farm. So the waters will be crowded. Oh wait, you can send merchant ships that you don't need to drive yourself. It's an automization simulation game.
But i also like the idea to combine the buildings when devs think that we should have the automated farming.
