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 GA5002-40T is a pair of original equipment replacement gas actuators designed specifically for the ST (Stainless) Series Smart Tabs trim tab systems. Rated at 40 lbs, these nitrogen-charged pneumatic actuators automatically respond to water pressure, boat speed, and payload — delivering hands-free trim control without any operator input underway.

Each actuator's chamber is filled with nitrogen gas and hydraulic fluid, functioning like a dampened spring with no internal or external metal components. This design provides a smooth, controlled reaction time of approximately 1.5 seconds, preventing abrupt tab movement and ensuring consistent, reliable performance on the water.

Key Features:

  • Designed as direct OEM replacement actuators for Nauticus ST (Stainless) Series Smart Tabs
  • 40 lb force rating for properly matched trim tab applications
  • Nitrogen gas and hydraulic fluid-filled chamber for smooth, dampened actuation
  • Includes protective rubber boot cover on each actuator
  • Sold as a pair — includes all mounting hardware for ST Series installation
  • Packaged in full-color clamshell packaging
  • Standard actuator length: 10 inches
  • Backed by Nauticus' 2-year warranty for original purchasers

Keeping your Smart Tabs system performing at its best means replacing worn actuators before they affect your boat's trim response. The GA5002-40T delivers the same fit and function as the factory-installed units, helping reduce bow rise, porpoising, and fuel consumption for a smoother, more efficient ride.
