  • FOR LONGBOARD , SUP AND INFLATABLE SUP (all brand inflatable sup boards and foam surfboards with AIR7 fin box or US box - contact us to confirm if not sure) suitable for use with most longboard / (stand up paddle) SUP / airSUP. most long board and stand up paddleboards use the universal fin system, which can take this replacement fin.
  • GREAT FOR BEGINNER AND KIDS : 1st time surfing can be dangerous, usually the fin is the sharpest part of you board, with this fin you can feel safer - the fin will bend and flex more and is harder to hurt yourself and others
  • GREAT FOR SURFER AND ADVANCED SUP : surf dumping shore breaks, shallow reefs. On your SUP : challenge white water, low level streams, river runs and fly fish in shallow lakes. This fin is flexible , in most conditions will not break, and less likely to break out your board's fin box!
