In order to keep at modeling I have to build small and my last effort posted on this forum was a 25' cabin cruiser. I have followed that up with a 25' sail boat ,designed by Devlin Boats (plans were $2). Scale was 1/24 resulting in a hull about a foot long. Construction was at beginnng level but figuring out how to scratch build it from the plans gave my brain a work out. All in all a satisfying project with lovely lines.
