XT™ Fin Stabilizer
Quantum Marine Stabilizers
How the Quantum XT™ Fin stabilizer system works:
XT™ Fin Stabilizer
Quantum XT™ (extendable) Fin Stabilizer is a semi-retractable boat stabilizer fin system. Quantum’s XT™ Fin stabilizer system provides optimal stabilizer performance at zero speed™ and underway.
Quantum’s XT™ stabilizer fin is designed with a retractable foil. For zero speed™ operations, the foil extends out of the pocket, increasing the effective fin area and improving zero speed™ performance. For underway, the foil remains retracted within a pocket in the XT stabilizer fin. By keeping the foil retracted, the total exposed ship stabilizer fin area is less. Reducing the fin area lessens appendage drag and total outreach.
In most cases, a single pair of Quantum XT™ stabilizer fins can provide equivalent performance to two pairs of conventional fin stabilizers, reducing cost and equipment footprint while attaining similar roll reduction onboard. This equates to a more comfortable experience for yachts and better operational readiness on military vessels, with less equipment to maintain.
In the case of impact or fault, the system can be operated as a conventional active fin stabilizer with the foil mechanically retained in the pocket. The foil and associated underwater components are fully serviceable with the vessel in the water.
Nearly all of Quantum’s stabilizer models can be configured to accept an XT™ Fin. Additionally, the XT™ Fin can be renovated on existing conventional Quantum systems with the conversion of some component parts and minimal structural modification.

01
Optimized Performance
The added foil area offers improved geometry for zero speed™ operation, such that the XT™ type fin is even more effective than a P-series Zero Speed™ fin of the same area. During underway operations, when less fin area is required, the foil is retracted resulting in reduced appendage drag.
02
Minimal Noise
Quantum’s stabilizer fins are designed with innovative features such as minimal hull-to-fin clearances and trailing edge vortex generators. These elements help to reduce hydrodynamic noise and vibrations while underway.
03
Minimal Maintenance
The units are designed for maintenance intervals corresponding to vessel haul-outs every other year. In the case that emergency maintenance or repair is required between haul-outs, the fin is designed for full serviceability to extendable components while underwater.
04
Environmental Awareness
The underwater hydraulic cylinder is powered from a hydraulic oil system distinctly separate from the main hydraulic system. Thus, bio-friendly hydraulic oil may be used to power the XT™ cylinder to minimize any negative impact on the environment.
