Does anyone know where I can find some really good info on aluminum boat building? Specifically on jigs and applying material. I've seen it done a few times but been busy on my own work to pay attention to what they are doing. Would like to build in the range of 16 - 20ft. I know there are a lot plans but are they proven? Seems there priority is selling them. I would pretty pi**ed to spend the winter build something and have it handle like a whale come spring. Thanks.
