I am selling a basically new electric SUP and surfboard fin which is in new condition and was never used in the water. These sell for about $790 new. It is a Boost Longe Range fin. They are popular and work well. It was a gift and I can't really use it. You can find these on Amazon and eBay for a much higher price. There is a lot of info there as well. It is in perfect shape. $290 or best offer.
