Abstract
A reinforced hull for a flat-bottomed boat comprises a bottom panel having longitudinal and lateral braces extending across an upper surface of the bottom panel of the hull. The braces are formed from channel members having outwardly and downwardly sloping legs connected together by a web. The lateral braces have notches formed in and extending upward from bottom edges of the legs with each notch sized to receive a longitudinal brace therein. Lower, outer corners of the bow are reinforced and an engine stand is welded to the brace assembly.
