XT with Hull Unit

3D Model

Quantum XT™ (extendable) Fin Stabilizer is a semi-retractable boat stabilizer fin system. Quantum’s XT fin stabilizer system for ships provides optimal stabilizer performance at Zero Speed and underway through fin variations. 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 stabilizer performance. For underway operations, 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.
