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 SX Series composite trim tabs combine automatic performance adjustment with rust-free durability for boats 21-25 feet with 150-220 HP outboards. Unlike traditional hydraulic or electric trim tabs, the SX system uses nitrogen gas actuators to automatically adjust trim based on boat speed, loading, and sea conditions—no switches or operator input required while underway.

How It Works:

The nitrogen gas actuator holds the trim plate down during acceleration, providing lift at the stern to minimize bow rise and accelerate planing. As boat speed increases and water pressure exceeds the actuator's load rating, the plates automatically move to a horizontal position to eliminate drag. An internal valve system dampens plate movement to provide smooth, stable performance without sudden reactions to minor pressure changes.

Performance Benefits:

  • Reduce minimum planing speed by up to 33%
  • Faster acceleration and improved time to plane
  • Increased top speed potential
  • Level, comfortable ride at lower speeds
  • Improved fuel economy and handling
  • Enhanced stability in turns and while crossing waves
  • Eliminates porpoising, sliding, and chine walking

Construction & Features:

Molded composite materials provide complete rust and corrosion resistance in fresh or salt water with zero maintenance required. Integrated tracking ribs improve handling at higher speeds. The system can be tuned during installation to maximize performance for your specific boat.

Installation:

Simple installation requires only a drill with 3/16" bit, Phillips screwdriver, and two wrenches. Most installations can be completed in under an hour with no through-hull drilling required. All mounting hardware, instructions, and templates included.

Specifications:

  • Trim plate size: 10.5" x 12"
  • Recommended boat length: 21-25 feet
  • Recommended horsepower: 150-220 HP
  • Material: Composite construction
  • Operation: Fully automatic, no electrical or hydraulic components

Seems relatively painless so far.

nice-easy

You guys beat all local auto part dealers in this area by far! I'm going to continue business with this company for a long time. Thank you very much for the savings!

great price and customer service

very good

very low prices

First order. Lets see how it goes.

Very easy to shop for the parts that I need and great prices.

So far everything seems good.

Thanks

Shopped for the best price I could find on my combo pintle/tow hitch and Autoplicity came in the lowest. So I'm expecting maybe a super long delivery right? Nope they shipped it Immediately and I just got it like 3 days later. I will order again in a heartbeat. Have no fear their a great supplier

thank you!

Great company!! Cheapest price I could find for an air filter and shipped really fast as well. Thumbs up!
