The M13 50-50 developed by Al MerrickThis is a performance hybrid that caters to the widest possible type and size of surfer and the widest range of wave conditions. Not to be confused with a funshape type board. Paddles like a funshape, but surfs like a shortboard. Available in either a squash or round pin, most common sizes are from 610 to 80.
