Smart Gyro Boat Stabilizer – 5,900–37,000 Nms Angular Momentum is an internal gyroscopic stabilization system designed to reduce uncomfortable boat roll caused by waves and changing sea conditions. Unlike external fin stabilizers, the gyro operates from inside the vessel without fins or other moving components protruding through the hull. It is suitable for motor yachts and other leisure vessels requiring improved onboard comfort while cruising, drifting, or spending time at anchor.

Six Smartgyro models are available to accommodate boats from 45 to 95 feet and up to 100 tonnes. The SG20 produces 5,900 Nms of torque and is intended for boats measuring 45–55 ft or weighing up to 25 tonnes. The SG40 delivers 9,100 Nms for 50–60 ft boats up to 40 tonnes. The SG60 provides 12,500 Nms for vessels measuring 55–65 ft or weighing up to 50 tonnes, while the SG80 generates 15,400 Nms for 60–70 ft boats up to 60 tonnes. For larger yachts, the SG120 offers 28,000 Nms for 70–85 ft vessels up to 75 tonnes, and the SG150 provides 37,000 Nms for boats measuring 80–95 ft or weighing up to 100 tonnes.

This boat gyro stabilizer uses a high-speed flywheel inside a sealed vacuum enclosure. Reducing air resistance around the flywheel helps improve operating efficiency while limiting heat generation and power consumption. A liquid-cooling circuit manages heat from the motor and spinning bearings while also cooling the inverter and hydraulic manifold. The pressurised closed-loop braking system uses hydraulic cylinders and a proportional valve to dynamically control the stabilising force.

Integrated motion sensors and an Inertial Measurement Unit continuously process the vessel’s movement. This control system manages the gyro’s response to counteract roll and automatically locks the counteracting forces during high-speed turns for smoother handling. Depending on the selected model, maximum anti-roll torque ranges from 15,500 Nm on the SG20 to 90,100 Nm on the SG150.

The modular mechanical construction is particularly useful for new-build and refit projects. Each marine stabilizer can be assembled, maintained and serviced directly aboard the vessel, helping avoid the need to remove the complete unit for routine maintenance. Installation is possible aft of the vessel’s midpoint, either on or off the centreline and above or below the waterline, subject to adequate space, structural support and professional engineering assessment.

Electrical requirements vary by model. The SG20 supports nominal 115V or 220V AC single-phase power with 12V DC control power. The SG40, SG60, and SG80 use nominal 220V AC single-phase power with 24V DC controls. The SG120 and SG150 require nominal 380V AC three-phase power and 24V DC control power. Final model selection should consider vessel length, displacement, operating profile, available installation space, and onboard electrical capacity—not length alone.

FAQs:

Q: Which Smartgyro model is suitable for my boat?
A: Selection depends on vessel length, displacement, operating profile, and installation conditions. The range covers the SG20 for 45–55 ft boats through to the SG150 for 80–95 ft vessels, but final sizing should be confirmed by a qualified marine professional.

Q: Does the Smart Gyro Boat Stabilizer – 5,900–37,000 Nms Angular Momentum work while the boat is at anchor?
A: Yes. A gyroscopic stabilizer can counteract boat roll while cruising, drifting, and at anchor because its operation does not depend on water flowing over external fins.

Q: Can this gyro stabilizer be installed during a refit?
A: Yes. Its modular construction supports both new-build and refit installations, and the unit can be assembled and serviced aboard the vessel when suitable space and structural support are available.

Q: Does the stabilizer require equipment outside the hull?
A: No. The Smartgyro system operates inside the vessel and does not require stabilizing fins or other moving components outside the hull.
