SereneLife Water Sport Kneeboard SLKB20 - 50 Inch Build

SereneLife Water Sport Kneeboard SLKB20 stretches 50.0 inches long, measures 20.0 inches wide, and weighs 8.7 lb. The board uses reinforced engineered polyurethane and a single-person design for tow sports behind a boat.

Specs And Setup

SereneLife lists a floating and stable platform base, form-fitting knee slots, and a universal board design for children, teens, and adults. The same page says the board is used in lakes, rivers, and oceans.

Target lists the board at 50 inches by 20 inches, with a 1-year limited warranty and a current price of $149.99 as of 09/16/2026. SereneLife's own page shows $173.99 and marks it unavailable.

Brand And Market Context

SereneLife is linked to Sound Around Inc., which is listed with a Brooklyn, New York address. The brand page for the SLKB20 keeps the naming simple: Thunder Wave Water Sport Knee-Board.

Who It Fits

The 50-inch length and 20-inch width put the SLKB20 in the compact tow-board lane, while the 1-year limited warranty gives the Target listing a clear retail signal. The board's 8.7 lb weight keeps it close to the light end of the kneeboard range shown by test publications.

Bottom Line For Buyers

SereneLife Water Sport Kneeboard SLKB20 is a straightforward tow board for riders who want a compact deck, a front hook, and a basic one-person setup. The Target price is lower than SereneLife's own listed price, and the model stays aimed at recreational use rather than advanced racing or trick riding.
