What Size Gyro Stabilizer Do I Need for My Boat?

Why Choosing the Right Size Matters

Choosing the right size gyro stabilizer is key to performance, safety, and onboard comfort.

Undersized units often underperform—especially in tight installs—while oversized models add unnecessary weight, cost, and power draw.

At Smartgyro, we aim for at least 80% roll reduction, achieved not through brute force, but by matching the stabilizer to your boat’s size, displacement, and design.

Key Factors to Consider When Sizing a Gyro Stabilizer

Proper sizing starts with a solid understanding of your vessel’s specifications. A few core factors will guide the selection:

• Boat length and weight displacement: Length overall (LOA) and displacement are primary indicators of the stabilizer’s workload. These are primary indicators of how much torque your vessel requires. Larger, heavier boats need more stabilizing force to counteract roll motion effectively.
• Displacement and Centre of Gravity: In addition to weight, the boat’s centre of gravity—often expressed as GMT (Transverse Metacentric Height)—is a crucial factor. A higher centre of gravity increases rolling momentum, requiring a more powerful gyro to compensate.

Smartgyro Stabilizers Guide: From Specs to Selection

Smartgyro offers a complete range of gyro stabilizers for boats from 40 to 95 feet and beyond. All models feature:

• Modular construction for simplified installation and servicing
• Vacuum and liquid-cooled systems for consistent performance

Understanding the Specs: Angular Momentum vs Anti-Rolling Torque

Two technical specs often raise questions:

• Angular Momentum: Think of this as the “stored energy” in the flywheel. Higher values mean more stabilizing potential.
• Anti-Rolling Torque: This is the real-world stabilizing force your boat will feel—the torque the system applies to counteract rolling.

Each model is recommended for a specific range of vessel length and displacement. Below, you’ll find a quick reference to help you identify the unit that might best suit your boat—complete with direct links to product pages and technical datasheets.

Every boat is different. Our dealer network is here to help you find the perfect stabilizer for your vessel, based on your exact specifications and performance goals.
