Got to the point where I a have flipped the hull bottom up and removed the stictches. I sanded the panel joints and have noticed that in a couple of spots there are dips in the joints from being a little over zealous with the use of the sander. The only way to see them is to sight down the length of the hull. Is there anything to worry about or should I just press on and chalk it up to experience for my first build? Overall it's been an enjoyable project.
