    The longboard box adapter provides versatile options

    I use the longboard box adapter with a nubster fin on my surfing SUP. My SUP has a quad fin setup, the adapter box and nubster fin adds a little lift in the tail down the line, and a little extra traction in tight turns. Great set up for a surfing SUP.
