<h3>About Nauticus: Pioneers of Automatic Trim Tab Technology</h3><p>Founded in 2000 and headquartered in Brecksville, Ohio, <strong>Nauticus, Inc.</strong> has built its reputation around one deceptively simple idea: trim tabs shouldn&apos;t require a pilot&apos;s constant attention. The result is their patented <strong>SMART TABS</strong> system — a fully automatic trim and stabilizer solution that has changed the way boaters think about on-water performance.</p><p>Before Nauticus arrived on the scene, improving a boat&apos;s trim typically meant investing in expensive electric or hydraulic hardware, complete with switches and manual adjustments. <a href="/11537-nauticus-bennett-trim-tabs-accessories-201695">Nauticus trim tabs and accessories</a> took a different approach. Their SMART TABS use a nitrogen gas actuator that continuously reacts to water pressure, boat speed, and load — all without any input from the operator. The system deploys the trim plates downward at slow speeds to maximize stern lift and get the boat on plane faster, then allows them to rise as speed increases, eliminating drag at cruise and top-end speeds.</p><p>The practical benefits are well-documented. <em>Improvements in acceleration, bow angle, ride and handling, top speed, and fuel economy</em> have been confirmed by OEM boat builders and numerous national and international marine publications. Nauticus backs this up with a money-back performance guarantee — a confident statement from a brand that has earned the trust of boaters worldwide.</p><h3>A Product Line Built for Every Boat</h3><p>Nauticus offers several distinct product families to match nearly any powerboat application. The original <strong>SMART TABS</strong> series covers boats from 10 to 30 feet. The <strong>SMART TABS SX</strong> line adds rust- and corrosion-free molded composite materials, making it ideal for both fresh and saltwater use. The compact <strong>ST1610 Series</strong> is designed for low-profile aluminum, fiberglass, and RIB boats with narrower transoms, while <strong>Mobster Tabs</strong> are purpose-built for bass boats, optimizing the &quot;hole shot&quot; and stabilizing high-speed runs. The innovative <strong>ProTroller</strong> series doubles as a trolling brake — a single lever flip converts the trim tabs into equal-drag braking plates on both sides, a feature beloved by walleye and bass anglers alike.</p><p>Installation is a DIY-friendly process. With a drill, a small drill bit, and a Phillips screwdriver, most boaters can complete the install in under an hour, with all mounting hardware, templates, and instructions included in every kit.</p><h3>Why Boaters Trust Nauticus</h3><ul><li><strong>No hydraulics or electric switches</strong> — the system is entirely self-contained and maintenance-free</li><li><strong>Nitrogen gas actuator technology</strong> provides smooth, dampened reaction to water conditions</li><li><strong>Marine-grade stainless steel and composite materials</strong> ensure corrosion resistance in fresh and salt water</li><li><strong>Boat-specific sizing</strong> — systems are matched to your boat&apos;s length, weight, and horsepower for optimal performance</li><li><strong>Money-back performance guarantee</strong> demonstrates confidence in real-world results</li></ul><p>Whether you&apos;re battling porpoising on a small aluminum fishing boat or chine-walking in a high-performance fiberglass hull, Nauticus has a solution.

Product Details

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.

Key Features:

  • Converts existing electric or hydraulic trim tab systems to fully automatic Smart Tabs
  • Designed for low-profile boats 18–20 ft and up to 3,000 lbs
  • 60 lb actuators provide proper resistance for this boat size range
  • No wires, no hydraulic lines, and no maintenance required after installation
  • Reuses existing trim plates — simply swap out the actuators
  • Not intended for high-profile boats
  • 5-year warranty on all metal and composite components; 2-year warranty on rubber boot covers and gas actuators
  • California Proposition 65 Warning: Product may contain materials known to the State of California to cause cancer or reproductive harm

Kit Includes:

  • Trim plates
  • Plate brackets
  • Actuators with boot
  • Transom brackets
  • All necessary hardware, backing plates, gaskets, and installation instructions

The Nauticus CK1820-60 is a cost-effective alternative to expensive repairs or full system replacements. Installation is straightforward using common tools, making it a practical upgrade for any boater looking to improve performance, handling, and ride quality.

Great prices and fast shipping.

Fast shipping, excellent product! Ordered the new SPC upper control arm ball joints and my truck rides like new again, Thank you!

The only issue was the shipping straps on both shocks were broken on one end only! Made it more difficult to install! But for the price I can't complain much! Thanks

Shopping took longer than I thought
