Problem? sizing stabilizer fins for the modern sailboat yacht hull form… creating fins large enough to perform both underway and at anchor suppliers without exceeding the hull envelope… or, keeping your OnAnchor™ or ZeroSpeed™ installation a two-marine fin installation instead of four…

Solution! Quantum XT™ fins, patented innovation from the world standard for yacht stabilizers, underway or at anchor. XT™ fins extend to provide additional marine lift while in ZeroSpeed™ or OnAnchor™ mode, and then retract for less drag while underway.

Quantum is proud to announce that the first two vessels fitted with the new XT (extendable) fins for ZeroSpeed™ are now in service and the reports are excellent. In both marine cases we would like to thank our customers for their faith in Quantum's ability to continually deliver improved performance through innovation.

XT™ fins allow us to increase fin area when you need it for ZeroSpeed™ or OnAnchor™; and return to our low-drag/high performance configuration while underway. Also, ZeroSpeed™ installations that previously might have required four fins can now perform perfectly with two- conserving power, space, and other onboard resources.
