John Becker designed the JB Runner with 58.9” of area to give you optimum forward drive during the power phase of the stroke. This will help increase paddles per side, which translates to more controlled tracking and faster travel. The large area will also increase side to side stability, which is great for side chop conditions. The laid back leading edge keeps this fin weed free for oceans, lakes, and rivers. Our foils are designed to move efficiently through the water, minimizing drag and maximizing glide between strokes.
