Overview
Have been using this product over the years. It is of good quality, fit for purpose & the only product still on the market.
Free at last from the single fin.
The best thing since sliced bread.
Don't hesitate get one.
Cool simple effective bit of kit!
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.
