Nauticus

<h3>About Nauticus, Inc.</h3><p>Nauticus, Incorporated, headquartered in Brecksville, Ohio, has been engineering some of the marine industry's most innovative performance solutions since its founding in 2000. The company set out with a singular focus: give boaters a smarter, simpler way to improve handling and performance without the complexity of traditional electric or hydraulic systems. The result was a patented technology that changed how the industry thinks about trim.</p><h3>The SMART TABS Difference</h3><p>At the heart of the Nauticus lineup is the patented SMART TABS system — <strong>a fully automatic trim and stabilizer solution</strong> designed for boats ranging from 10 to 30 feet. Unlike conventional setups that require switches, wiring, or hydraulic plumbing, SMART TABS use a nitrogen gas actuator that continuously reacts to water pressure, boat speed, and payload without any input from the operator. The actuator is sealed in a durable EPDM rubber boot for extended service life, and the trim plates themselves are constructed of marine-grade stainless steel or rust- and corrosion-free composite materials, depending on the model series.</p><p>The physics behind the system are elegantly straightforward. At slow speeds, the trim plates deploy downward to increase stern lift, helping the boat level out and get on plane faster. At cruising speeds, water pressure pushes the plates upward, but they remain under load — functioning much like shock absorbers to smooth out the ride across chop and wake. The system self-adjusts continuously, so boaters never have to think about tab position, whether they're pulling a skier, running offshore, or navigating a busy channel.</p><p>Documented improvements include better acceleration, reduced bow rise, improved top speed, and fuel efficiency gains of up to 11% — results verified by OEM boat builders and published in numerous national and international marine magazine tests. Nauticus backs this confidence with a money-back performance guarantee.</p><h3>Product Lines for Every Application</h3><p>Nauticus offers several distinct product families to match different hull types and use cases. Explore the full range of <a href="/201109-trim-controls-nauticus-11537">Nauticus Trim Controls</a>, which include the actuators, hinges, and control hardware that form the backbone of the SMART TABS system. The original SMART TABS series is built for maximum mounting versatility on aluminum, wood, and fiberglass transoms. The SX Series adds corrosion-free composite construction ideal for saltwater applications. The ST1610 Series is purpose-built for low-profile fiberglass, aluminum, and RIB-design boats with transom widths under 10 feet. For anglers, the Protroller Series incorporates a lever mechanism that converts the tabs into trolling brakes when needed.</p><p>Beyond the core trim tab kits, Nauticus also supplies a broad range of <a href="/200608-trim-tabs-accessories-nauticus-11537">Trim Tabs &amp; Accessories</a> — including replacement nitrogen gas actuators, mounting hardware, and system-specific components — making it easy to maintain or upgrade an existing installation without replacing the entire system.</p><p>Whether you're troubleshooting porpoising, chine walking, or simply want a faster hole shot and a smoother ride, Nauticus delivers proven, maintenance-free solutions that install quickly with common hand tools and require no specialized marine expertise.</p>

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
