LR170 Fin Stabilizers – Stabilis Electra (CMC Marine) in California

California’s Pacific swell, shifting wave periods, and wake-heavy coastal traffic can make displacement and semi-displacement yachts roll when you want the boat to feel calm—at anchor, on passage, and during long coastal runs. The LR170 Fin Stabilizers – Stabilis Electra (CMC Marine) are engineered specifically for displacement and semi-displacement yachts, delivering high platform stability through displacement-optimized fin geometry, powerful actuator design, and precise multi-axis motion sensing.

The LR system uses a precise inertial detector to measure roll, pitch, and yaw, allowing stabilization response to match real-world conditions as they evolve. It also supports broader onboard integration, with the capability to manage controls for up to 8 systems, making it well suited for modern yacht installations along the California coast.

Purpose-Built for Displacement & Semi-Displacement Yachts

LR stabilizers are designed around the way displacement and semi-displacement yachts operate—steady cruising, long-range comfort, and roll-prone anchorages. LR170 is intended for larger, higher-demand installations and features:

• Compact yet powerful actuators built for strong stabilization authority
• Fin geometry designed to perform efficiently on displacement hulls
• Improved stabilization behavior for a calmer onboard platform
• System capability that supports fins up to 7 m²

High Stability Through Multi-Axis Motion Sensing

LR uses a precise inertial detector that measures:

• Roll (side-to-side motion)
• Pitch (bow-up/bow-down motion)
• Yaw (heading oscillation)

By tracking all three axes, the system can deliver refined stabilization control—especially valuable in California’s mixed swell and wake environments where motion can be complex and constantly changing.

Integration-Ready Control Architecture

The LR platform can integrate controls for up to 8 systems, supporting centralized coordination of onboard functions. This integration capability helps streamline operation and supports a more refined, confidence-inspiring onboard experience.

Engineering & Construction Details

LR170 is built with heavy-duty marine components selected for strength, corrosion resistance, and dependable sealing:

• Fin connection: Precision machined oversized self-locking taper
• Shaft: 140 mm duplex stainless steel
• Actuator housing: High-strength ductile iron
• Bearings: Heavy-duty tapered roller bearings (upper and lower)
• Lower seal: Two double-lip seals for maximum seawater protection, accessible in a 316 stainless steel retainer
• Upper seal: Double-lip, spring-loaded seal for grease retention and protection against external contaminants
• Lubrication: Pre-packed water-resistant grease for lifetime maintenance-free service; reduction gearbox lubricated with mineral oil
• Fit & finish: Painted RAL 9016 and polished

Why LR170 Makes Sense in California

For displacement and semi-displacement yachts cruising California waters, LR170 is designed to deliver stability that you can feel—less roll at anchor, smoother motion on passage, and better composure in wake-heavy harbors. With displacement-optimized fin geometry, high-power actuator design, multi-axis inertial sensing (roll/pitch/yaw), and integration-ready control capability, LR170 helps keep your yacht steadier—so every mile feels calmer and every moment onboard is easier to enjoy.
