Hi I am trying to built a rowing boat for myself, and I have all the materials, all the tenons, hull planks and keels etc. I have improving the keels so they are about 13 in quality, and my skill in ship building above 6 now. But I cannot figure out how to build the "unfinished boat". I can only carry 1 keel, and when activating that and clicking on the other one on the ground, I do not get any option to create the boat. What am I doing wrong? Is my ship building skill too low? if so, what is the minimum skill for this? Please help
