Did me some research on Rich Line Boats and What I found was it was made in Richland, mo.. The company was sold to a Jim Dorris in 1973, And continued to make Rich Line boats by Play Craft till 1994 When he started a whole new company called Challenger Boats. According to the article I found on line he refuses to answer question about Rich Line Boats. The 14' Challenger aluminum boat was rated for a 35 H.P. motor and is made from O.o64 gauge aluminum.
