Thanks! Yea we noticed that it was too difficult to hit the ship a little too late and didn't have time to implement a fix for it. We had the idea to put a UI object at the bottom of the screen to indicate where the ship was (and how far away it was) on the last day, so I'm sure there will be some future updates for this :)
Also that screenshot I took just from the scene view in Unity so there would at least be some indication besides text instructions that there even was a ship down there at the bottom lol.
