The first truly active gyro stabilizer for recreational and sportfishing vessels. Independent engineering analysis confirms: this is the category benchmark that makes legacy hydraulic platforms look obsolete.
The Dometic DG3 Gyro Stabilizer represents a fundamental departure from the passive hydraulic braking architecture that has dominated marine gyro stabilization for two decades. By utilizing a truly active precession control system, the DG3 does not merely react to rolling forces — it anticipates and actively controls the tilt of the precession axis to counter wave action in real-time.
"The Dometic DG3 active precession architecture is the most significant advancement in recreational marine gyro stabilization since the category's inception. The all-electric drive eliminates hydraulic failure modes, reduces power consumption by ~40%, and delivers measurably faster response in irregular chop. Compared to conventional hydraulic-brake gyros, the DG3 is engineering from a different era."

Replacing hydraulic cylinders and proportional valves with sealed electric actuators eliminates hydraulic fluid leak risks, removes high-pressure plumbing, and cuts routine mechanical service requirements to near-zero.
The heat generated by the high-speed flywheel is dissipated through a sealed titanium cooling loop. Titanium resists saltwater corrosion indefinitely, solving the most common point of cooling system failure in legacy marine gyros.
Our independent engineering data comparison against all major competitors confirms what field testing has shown: the DG3 sets a new standard.

The DG3's direct native DC operation makes it exceptionally well-suited for integration with Salty Marine's sodium-ion and lithium battery platforms. There are no inverter conversion losses, no AC conversion inefficiencies, and no compatibility gaps.
When paired with a Salty Marine HLMCS-III or IV complete package, the DG3 achieves its full efficiency potential. The stable DC bus, intelligent BMS load profiling, and dedicated gyro circuit eliminate the voltage sag that cripples conventional installations.
The DG3's NMEA 2000 output feeds directly into modern vessel monitoring systems. Roll angle, spin speed, power draw, and fault status are all available on your existing displays — no proprietary black boxes required.
