Boat actuator ANT-63

ANTUATOR was founded to create compact, smart, waterproof, and durable in-line actuators. The name combines “Ant” for strength and precision in a small form, and “Actuator” for motion and automation. Like ants, our products are resilient and efficient—ideal for RV roofs, pergolas, and yacht systems. Designed for harsh environments, they offer powerful performance in a sleek, compact form.

How a Single Actuator Stabilizes a Boat’s Trim in Rough Seas
When a vessel is cruising at high speed, facing choppy waters, or experiencing uneven loading, stability can quickly become a challenge. The bow might pitch up, the hull may roll from side to side, or the boat could drift off course—reducing both efficiency and comfort.boat actuator.jpg To counter these issues, more and more boats are equipped with trim tab systems—adjustable plates mounted on the transom that fine-tune the vessel’s running angle in real time.
And at the heart of this system, executing every precise adjustment, is a single key component: the electric linear actuator.
What Trim Tabs Do on a Boat
Trim tabs are small, movable metal plates installed at the stern, typically one on each side. When the boat is underway, the control system adjusts their angles based on speed, heel, and wave data:
Press down  the port trim tab → Reduce port-side lift
Press down the starboard trim tab → Correct starboard lift or drift
Lower both tabs together → Bring the bow down for faster planing
Raise both tabs → Reduce drag and increase top speed
These quick, precise movements are made possible by the actuator driving the tabs up and down.
The Challenges in a Harsh Marine Environment
Operating in constantly changing wave patterns and under high water pressure demands more than just power—it requires durability, waterproofing, and absolute reliability.
That’s why ANTUATOR’s ANT-63 marine electric actuator was engineered specifically for trim tab systems on yachts, fishing boats, patrol vessels, and rescue craft.

Key Advantages of the ANT-63 Trim Tab Actuator
1. Powerful Load Capacity – Steady and Strong Drive
With a rated load of 2,300 N and a maximum push force of 2,750 N, the ANT-63 ensures stable trim tab operation even at high speeds.
2. Exceptional Self-Locking Strength – No Back-Drive
An 8,000 N self-locking force keeps the trim tab firmly in position, even during power loss or heavy wave impact.
3. IP67M Waterproof Rating – Built for Submersion
The actuator meets IP67M standards for underwater protection, enabling long-term operation in splashing, rain, and submerged conditions.
4. 500-Hour Salt Spray Test – Corrosion Resistance
Anti-corrosion coating and marine-grade materials withstand harsh saltwater and humid environments.
5. Integrated Limit Switch Protection
Prevents over-travel damage by cutting power automatically at full extension or retraction.
6. High-Strength Construction – Built to Last
A precision transmission system and reinforced aluminum housing ensure long service life, even under vibration and shock.
Why Choose an Electric Solution Over Hydraulic Systems?
Electric actuators like the ANT-63 provide:
No oil leaks – Environmentally friendly
Low maintenance – No pumps or fluid changes
Simplified installation – Fewer components and wiring
Smooth,precise control – Ideal for automatic trim systems
Applications:
Sport yachts
Fishing boats
Patrol and rescue boats
Passenger ferries
Commercial workboats
Whether paired with a manual helm switch or an automatic boat leveling system, the ANT-63 delivers consistent performance in every condition.
Final Thoughts:In rough seas, a single actuator may seem small, but it plays a decisive role in stabilizing your boat’s running angle, improving efficiency, and enhancing passenger comfort.
With the ANT-63, boat builders and owners get a trim tab actuator that’s strong, waterproof, corrosion-resistant, and maintenance-free—ready to perform in the toughest marine environments.
