This is a vintage Max Mcdonald shape. While talking with him he said he shaped it while shaping for Infinity around 1977-78 and thinks there are very few survivors out there with just his first name on it. Measures 6'10"x16 x21 3/4 x12.5 x2 7/8. has three 1/8" redwood stringers and the outside two have 1/2" balsa stingers as well. I Had Ropers in SD make it water tight. Comes with the original 7" fin. I can meet up over by O'side or C'Bad if needed.
