Nauticus CK1820-60 Smart Tabs Trim Tab Conversion Kit 18-20ft 3000lb

The Nauticus CK1820-60 Smart Tabs Conversion Kit is designed for boaters who want to upgrade their existing electric or hydraulic trim tab system to a fully automatic Smart Tabs system — without the cost of a full replacement. Sized for low-profile boats up to 20 feet and 3,000 lbs, this kit replaces your old actuators and delivers hands-free trim control with zero wiring, zero hydraulic lines, and zero ongoing maintenance.

Smart Tabs work as an extension of the boat's running surface, automatically adjusting to water pressure, boat speed, and payload. At low speeds, they deploy downward to increase stern lift and help the boat get on plane faster. At cruising speed, they retract to a horizontal position and provide active ride stabilization — similar to a suspension system.

• Designed for low-profile boats 18–20 ft and up to 3,000 lbs
