Quantum XT™ Fins

The XT™ Fins are the most popular system to date

The main stabilizer fin houses another fin or “foil,” designed to extend or retract based on the speed of the vessel. To maximize the performance at zero speed, the foil is extended, providing 30% more surface area, while generating 100% more lift force. To maximize the performance underway, the foil is retracted, reducing the surface area and the corresponding drag. Standard fins are frequently converted to XT™ Fins.
