Measure Twice Cut Once
I made a potentially catastrophic mistake when building the centerboard case this past week. The centerboard case is a slot in the boat in which you can take the centerboard in and out of the boat. It is a very important part, and if it is built incorrectly the boat can have internal leakage from water. It spans 24" between frames 3 and 4 which is roughly in the middle of the boat. I have now built two of these, because I completely misinterpreted the instructions. Instead of building the sides at 1/4" wide I built the sides at 3/4" wide making the centerboard case about 1" wider than it should be. Luckily seeing that this didn't look quite right, I contacted Greg and Chris my Australian boat builder mentors. I didn't show them a photo of what I did but they will be able to see it now on the blog. (I was too embarrassed to show them at the time) They were very helpful, and Chris sent me drawings of various ways that the centerboard case could fit into the keel and strong bow. With recommendations of which one he prefers. I think it's important to post about these things because I don't want to skew the reality of this project. It's not perfect and it's not beautiful it's a learning experience, and it's also a lesson on asking for help.
You can see here that if I cut out a hole for the centerboard case it would have only given me a 1/2" gap from around the keel which is not enough and could have potentially split the keel.
