BUY HS120 Fin Stabilizers – SE Stabilis Electra System (California)

California’s Pacific swell, afternoon wind chop, and high-traffic waterways can make even large yachts feel busy at speed. The HS120 Fin Stabilizers (SE Stabilis Electra System) are built for bigger planing yachts that need strong stabilization authority, fast response, and dependable marine-grade construction—helping deliver a smoother, more controlled ride along the California coast.

The HS System is an evolution of the SE Stabilis Electra platform, engineered to suit virtually all hull shapes and optimized for planing yachts. Upgrades focus on improved fin efficiency for reduced resistance, electronics designed for faster stabilization performance, and the ability to control integrated onboard systems—such as steering and intruder functions—alongside fin operation.

Built for Large Planing Yachts and Demanding Sea States

HS120 is designed to deliver high stabilization capability while maintaining efficient hydrodynamics. In California conditions, that translates to:

• Improved comfort and reduced fatigue on longer coastal runs
• Better control when pushing through swell and wind-driven chop
• Reduced roll motion for guests and crew at cruising speeds
• A refined fin profile aimed at lowering drag while maintaining authority

Key System Advantages

• Evolution of SE Stabilis Electra, optimized for planing yachts
• Efficient fin profile designed to reduce resistance
• Upgraded electronics for faster response and performance
• Ability to manage integrated systems (steering/intruders) in addition to fin control
• Heavy-duty mechanical design for long-term durability in marine environments

Engineering & Construction Details

HS120 is built around robust, service-minded components designed to withstand saltwater exposure and continuous use:
