The Surf Station Fro Back is a throwback surfboard to the 1970's when twin fins and Quads became popular. The board is designed in St. Augustine, Florida, made overseas, and is a wider, shorter board than a traditional tri-fin. It is made to catch waves easily and turn easy too. It is super loose as a twin fin while the quad holds in a little better and may be faster down the line. Poly and epoxy construction Fro Backs are available, and sizes range from super small 4'10's all the way up to 6'10.
