The Sea Juice fins are designed as either a back/trailer fin for a thruster set up, used as 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. 

The fins are designed to propel watercraft with forward thrust, increasing manoeuvrability, allowing you to make tighter turns, accelerating drive and speed with more control. 

The inspiration for the fins has been created from the thrust and projection generated from fish swimming downstream in pursuit mode. The fins have increased tip area and a swallowtail, similar to the fastest fish in the ocean which creates a vortex. 

Vortices carry the momentum to move fish forward in water, each stroke of a fish tail creates a vortex ring which fuses with those of prior strokes to form a linked zigzag chain. Circular flow around the vortex filament shoots fluid backwards through the centre of the ring propelling the fish in the opposite direction.
