VT900 VIATOR MC² Fin Stabilizers in California

California waters can go from calm to chaotic fast—long-period Pacific swell, afternoon wind chop, and constant wake traffic around marinas and anchorages all add up to one thing: roll. VT900 VIATOR is MC²’s advanced fin stabilizer designed to reduce vessel roll by up to 95%, delivering steadier comfort at anchor and underway with real-time response and smooth, quiet operation.

VIATOR pairs a hydrodynamically optimized carbon fin with an ultra-efficient electric drive and a control unit that analyzes and anticipates the boat’s motion, continuously adapting stabilization behavior as conditions change—whether you’re holding position in a busy anchorage, cruising the coast, or running at higher speeds.

Designed for Fast Response and Seamless Comfort

Unlike systems that react after the boat has already started to roll, VIATOR is built around control logic that evaluates vessel dynamics and adjusts stabilization algorithms on the fly. This “always adapting” approach helps keep motion more controlled across the variety of sea states typical along the California coast—especially when swell direction and wave period shift throughout the day.

Performance Without Sacrificing Speed

The VIATOR fin profile was developed using advanced fluid dynamics simulation to reduce drag and limit impact on boat speed. The result is strong stabilization performance per square meter of fin area, helping support stabilization on larger vessels while keeping efficiency in mind.

Operating Modes for Real-World Use

Every boat and every day on the water is different. VIATOR offers six selectable modes designed to make operation simple while tailoring stabilization behavior to how you’re using the yacht—anchoring, swimming, cruising comfortably, or pushing to higher speeds.

Technical Highlights

• Compact, space-conscious design
• 360° rotation capability
• Easy installation approach
• Active stabilization at anchor and underway
• Fast fin actuation: up to 90°/sec
• Quiet operation: < 65 dBa

High-Efficiency Electric Drive Options

VT900 is available with high-efficiency synchronous motor configurations that support multiple power architectures, including 24 Vdc and AC supplies (240 Vac / 400 Vac)—ideal for modern yachts with diverse electrical systems.

Direct Drive Safety (Shaftless Unit)

VIATOR uses a direct drive, shaftless fin unit design intended to improve safety. In the event of an impact during navigation, this approach helps protect both the hull and actuator from potential damage.

Low Noise Gearbox + Optimized Fin Shape

A precision, low-play gearbox works together with the fin’s hydrodynamic profile to reduce noise—minimizing both mechanical sound and water-related noise around the fin while underway.

Materials and Hull Compatibility

• Fin material: Carbon fiber
• Housing material: Aluminum and stainless steel
• Hull compatibility: Composite (fiberglass, etc.), aluminum, and steel hulls
• Not compatible with: Wooden hulls

Maintenance

• Annual service (boat lift/haul-out): check and replace zinc if needed
• Replace the protective seal during hauling, as required

Why VT900 VIATOR Makes Sense in California

For yacht owners running the California coast, VT900 VIATOR is built for the conditions you actually face—swell at anchor, chop on the beam, and changing sea states throughout the day. With real-time response, full-rotation capability, efficient electric drive options, and a drag-conscious carbon fin design, it’s a fin stabilizer built to keep your yacht steadier so you can enjoy more comfortable cruising, cleaner anchoring, and better onboard living—no matter what the Pacific decides to do.
