Thanks for the english version :D the quest made it sound like you only needed 10 logs and 3 dust to make the raft but I guess it takes a lot more.
Here is a guide specifically for the fishing boat. Might be helpful for someone that has not made it yet. https://docs.google.com/document/d/1mN5Ws_9iktz_GfhgRhA1e3Y-QTNZmcGTNsNY6HuMrsM/edit
I just made my First Fishing Boat last night, Started on my 2nd one as well. The Sap is prob the hardest thing to get, as you have to go get it manually. Everything else you get from Nodes. Well black power too is manual.
