From small boats to large craft, the Nauticus® Smart Tabs™ SX Automatic Trim and Stabilizer System provides unequaled performance with smoother and faster acceleration. The durable, maintenance-free Smart Tabs SX system improves fuel efficiency by up to 11% while also improving handling by automatically adjusting to water pressure. At slow speeds, the Smart Tabs SX deploy downward to increase stern lift and keep the boat level, allowing the boat to plane easier and faster. At cruising speeds, Smart Tabs SX push to a horizontal position but remain under load, creating ride control like shock absorbers. Molded from rust- and corrosion-free composite materials, the easy-to-install Smart Tabs SX system uses a nitrogen gas actuator to hold the plates down during acceleration and provide lift to the stern. Plate size and pressure are determined by the boat size and horsepower at the time of installation. After installation, Smart Tabs SX can be tuned to your preference. Includes DVD of demonstration and installation.
