The Sea Juice fins are designed as either a back/trailer fin for a thruster set up, used as 2 back fins in a quad or as a single fin from the Single Fin Range. They have increased tip area with a swallowtail that creates forward thrust similar to the fastest fish in the ocean. The configuration of a swallowtail provides a lower aspect ratio at the fin tip to maintain speed through turns. Give your board some 'JUICE' and get a hold of a Sea Juice Fin, an innovation in fin design.
