Yacht stabilizers
CMC Marine fin stabilizers — installed, serviced and kept reliable. Hands-on experience with the systems that keep a yacht steady at anchor and under way.
Stabilizers are unforgiving: part hydraulics, part electronics, all precision.
A stabilizer that knocks, drifts or throws faults ruins time on board — and left alone, small issues become expensive ones. We know the CMC Marine platform inside out: the actuators, seals, sensors and control logic that have to work together for the fins to do their job.
Whether it's a new install, scheduled service or a fault mid-season, we diagnose the real cause, put it right and confirm it on a sea trial before you rely on it.
Install, service, and keep them right.
Installation
Fin-stabilizer installation and commissioning, coordinated with the yard and sea-trialled.
Service & maintenance
Scheduled servicing to keep fins responsive and reliable — before the season, not during it.
Fault finding
Knocking, drift, error codes or weak stabilization traced to the real cause — hydraulic or electronic.
Seals & actuators
Shaft seals, actuators and hydraulic components inspected, replaced and pressure-verified.
Calibration & updates
Sensor calibration, control-system checks and firmware updates for correct fin response.
Sea trials
Every job confirmed on the water — proven stabilization before we hand it back.
When the fins aren't right.
- Knocking or clunking from the fin boxes
- Poor or uneven stabilization at anchor
- Hydraulic leaks or low system pressure
- Fault / error codes on the control panel
- Seals weeping at the shaft
- Sluggish or delayed fin response
- System dropping into bypass
- Calibration drift after a haul-out
We know this platform.
Stabilization is where our founder's marine-electrical career led next — working directly with CMC Marine systems. That means real familiarity with how the fins, hydraulics and controls behave, not a manual read on the way to the boat.
The result: faster diagnosis, correct parts, and stabilizers that actually hold the yacht steady.
