Ok so I have the plans to build a grand laker however when i look online at pics of these boats quite a few of them have horizontal braces on the inside. I know there is a better name for what I am talking about but the word has eluded me. OK so question is can i build this boat with 5/16 or 3/8 strips and have enough strength and rigidity to put a 10hp motor on it? Sorry about my grammar. I have never been a writer or good student of the subject. Math was my strong suit.
