There really needs to be more visual contexts for players to comprehend the game state, like arrows indicating which ship will go to which tile in the next turn. That being said, game jam is about demonstrating ideas so I would say this is an excellent one! The concept really has potential to be further developed into a full game.
My suggestion is that for this demo you might want to remove the wind event, because without clear visual contexts it makes things more confusing, and thus feels unpredictable.
