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>

Why buy a manually adjusting trim tab set when you can get the automatic trim tabs that will self adjust and perform better for less money?

Our breakthrough technology in trim tabs is completely automatic requiring no operator adjustment while underway. Nauticus trim tabs self adjust according to how you load and maneuver your boat.

The nitrogen Gas Actuator provides LIFT at the stern of the boat by holding the trim plate down during acceleration. The amount of LIFT is determined by the actuator load rating and the trim plate adjustment, which is done at the time of installation.

  • Reduce the minimum planning speed by up to 33%
  • Faster Acceleration
  • Increase top speed
  • Provide a level, more comfortable ride at lower speeds
  • Improve fuel economy, handling and safety

NO HYDRAULICS - NO ELECTRIC SWITCHES

Nauticus trim tabs are completely automatic requiring no operator adjustment while underway.

The nitrogen Gas Actuator provides LIFT at the stern of the boat by holding the trim plate down during acceleration. The amount of LIFT is determined by the actuator load rating and the trim plate adjustment, which is done at the time of installation.(see installation instruction).

SPEED REGULATED

Nauticus trim tabs start in a downward angel to maximize lift at slow speeds. As the boat accelerates, the water pushes up on the trim plates providing lift to the stern which minimizes bow rise, and allows the boat to plane quickly.

Once the water pressure exceeds the actuator load rating (maximum lift) the trim plates move up to a horizontal position eliminating any drag.

BOAT STABILIZERS

Even when cruising SMART TABS continue to work like shock absorbers. The constant adjustment to sea conditions allow SMART TABS to provide remarkable stability in turns, while crossing waves, while cruising, and while running at maximum speeds. No more sliding, porpoising, or chine walking.

ONE OF A KIND

The unique system is the only one of its kind in the industry. The internal valve system is truly "smart" in its design of controlling you boats performance.

It will reduce the minimum planning speed by 33%

Provide a level, more comfortable ride at lower speeds

Improve economy, handling and safety

As the boat speed increases, the water pressure also increases. Once the water pressure exceeds the Actuator load rating (maximum LIFT period) the trim plates begin to move upward until they are horizontal with the bottom of the boat.

The internal valve system dampens the trim plate movement which eliminates any instant reaction to minor water pressure variances. Nauticus trim tabs provide smooth and undetectable reaction to boat speed creating a level, more comfortable ride at lower speeds.

INSTALLATION IS SIMPLE

With an electric drill, small drill bit, a phillips screwdriver, and two wrenches, just about anyone can install SMART TABS in less than an hour. Professional installers should be able to install SMART TABS in 30 minutes or less.

All mounting hardware, instructions, and templates are included.

SMART TABS require NO THROUGH HULL DRILLING

They have easy forms and fair prices

great item at good price, with fast shipping

Very pleasant order over the phone. Gentleman was smart, cheerful and helpful.

Great price, I shopped around for hours on the web and no one could beat it, even with the shipping costed added in. The shipping was a little high, however, the price was so low it was still the best price around. Shipped in less the 48 hours. Thanks for a great deal and great experince.

Wow fast shipping and great price! Thanks autoplicity!

Good website, Thought the fuel jugs would come with a pour spout. They are only the jugs though.

Great Seller. Fast Shipping and great prices!
