Lol, the same goes with the ship, if they make it compelling to stay, people will stay. Currently it is completely boring, it looks like you are slowly passing through a sea of jelly. If they made it so rare monsters could spawn on the ship, I am sure people would love to stick around, however, what is the point of sticking around for like 10 minutes just for a scenic view of the gelatin sea.
There is literally nothing to do but stand around and speak to the single NPC captain. What could you possibly argue to justify sticking around for a pointless ferry ride other than "immersion" in the sea of jelly where it looks like the island is moving towards you?
