The boat has a hole in it.
Try to find a plank. ?
Read the old wooden sign at the parking space. It falls off.
Now you just need something to stick the plank into the boat.
You would need some sticky substance. You are in a camp, by the fire, after all.
Find some marshmallows. ?
Go into the Dorms and look at the bottom right bunk pillow.
Now just melt them by the fire.
So, you would need some kind of a pot, right? ?
There's pots in the canteen. Take one from there.
Put the marshmallows into the pot and melt them with the fire. Then you can combine them to the wooden plank and the patch for the hole in the boat is ready.
Find some gas for the boat.
