I forgot to mention this but building the boat was very confusing and when I fell of the map I completely forgot about it. When I looked at the barrels in a specific way it showed press e, I did but nothing happend.

Yeaaaah I knew I should of created a tutorial lesson has been learned. When you found the axe near the barrels you press E which made you pick up an axe then you press 1 to equip it. Then you just chop down trees by spamming right click and the tree chops down picking up logs. Then you walk over to the boat and press E.
