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. 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.
The DYNA-FOIL™ active fin stabilizer systems underwent extensive third-party model testing by the MARIN (Marine Research Institute Netherlands) to improve performance at anchor or zero speed and underway relative compared to a traditional fixed fin stabilizer. DYNA-FOIL™ stabilizers retract completely into a full pocket or to a parallel position to the hull.
