Well, she's had her maiden voyage! Thanks to a member here (Shipmate60), I was able to visit a nice piece of water and put her into her natural environment. (My home water is weed-ridden, and we are about to be evicted anyway, but that's another, sadder, story).
Off she went, looking splendid (to my eyes at least), and all was well for about 2 minutes. Then the steering stopped working. Hmmm.... I wonder why? Fortunately, she steers very badly in reverse, so although the rudder was locked hard over, I was able to slowly reverse to the bank. When I went to retrieve her, she had a load of water on board. What the....?! I had done a bath test and had not a single drop of leakage, and I certainly hadn't been inundated by any bow wave.
Long story short - put her back in the bath when I got home and immediately saw the problem. I have a split in one of the planks. Initial relief - at least it's not my workmanship.

But annoyance follows - I had noticed a small crack in that plank when I was building and foolishly assumed that epoxying inside and out would stabilise and waterproof the crack.

The boat has been in my study since completion (getting the paint nice and hard prior to polishing out the oversprays), and the weather has been nice and hot, so I guess that opened up the crack. It doesn't look too bad from the inside, but turn the boat over and it becomes obvious. Anyway, here are the pictures.


Should be fairly straightforward to fix. I'll give it a few days to dry out properly then open up the crack and fill it with thickened epoxy. A quick repaint and nobody will be any the wiser. Except you if you are reading this.
