Early Stumpknockers were flat bottom. They do make some with a little V that remind me of an Old Timer. Mom has the flatbottom 17' Stumpknocker that gets around nice with a 60 4-stroke. Fairly shallow runner but the NV goes places that mud motors and airboats need only apply. As evidenced by the lack of gelcoat on the bottom... Started out as a baby in the 12' SeaKing with 4.5 Merc. It wouldn't plane but the fish didn't care..
