Helps maneuver in tight areas. Love it

Was perfect for a low water expedition!

I love this fin for surfing. It makes the board nice and loose for tricks and shinnaniggins while on the wave.

I was unsure if I wanted this because the standard fin retracts as well but I’m glad I got it. Smooth riding on a shallow river and it was easier the swap out than I thought it would be. The side fins are flexible and the same depth as this retractable center fin for stomp box

Great river fin. We floated the Green River through Utah and the board and fin were perfect
