The Humphree Effect

Introducing 3-component stabilization

Total stabilization Elevated™

Take control of every wave, wake, and turn with Humphree Total Stabilization Elevated™. The seamless integration of electric fins, gyro and interceptors working as one unit brings stabilization at sea to a whole new level. Engineered for leisure yachts from 35 feet, this complete system combines the strengths of all product types to deliver unrivaled comfort, performance and confidence at sea.

Engineered as one

What sets our three-component system apart is that all components are fully integrated, forming a complete, collaborative system. Through a central control unit, the system continuously monitors vessel motion and coordinates all components in real time. It does not simply react to waves. It anticipates and proactively counteracts motion before it occurs.

Interceptors
Improves acceleration, fuel efficiency, trim control and stabilization at speed.

Fins
Reduces roll motion and increases comfort at all speeds.

Gyro
Eliminates roll at zero-speed and low-speed operation.

Why Total Stabilization™

▪ All-speed performance
▪ Smarter fuel efficiency
▪ Faster time-to-plane
▪ Confident cornering
▪ Designed to fit your boat
▪ Low maintenance—no hassle

3 component stabilization

3-component solutions

With three fully integrated components operating together, the system delivers stability across the entire speed range, from zero-speed to full throttle. Depending on vessel type, the roll reduction can reach up to 95%.

Interceptors, fins and gyro combination.

2-component solutions

Our three product categories can be freely combined to match your specific needs and use case. When integrated into the same system, the components interact and build on each other to deliver maximum stabilization performance.
