FORTRESS Mast

The FORTRESS is much more than a mast: it is a statement of strength. Designed to meet the demands of the most imposing sizes and the extreme stresses of very large wings (like the155LR), it redefines the standards of bending and twisting. In our test bench, it outperforms without hesitation the highest-end models from global leaders.

Innovation : A structure made of UHM Carbon (Ultra High Modulus) capable of maintaining a thickness of 13.5 mm in the lower part while offering colossal structural rigidity.
Feeling : Unwavering stability. Even under the pressure of a powerful rider or a giant wing, the mast does not flinch. The transmission is direct, the pop is massive, and the twisting is completely locked.
Usage : Essentially for Pumping (Engaged Dockstart), but also for WingFoil.

The opinion of the Ketos Team :

"It is the mast of all superlatives. It is called the Fortress because it creates a feeling of total security: nothing moves, even when you push hard with a 1.5m wingspan. For larger sizes or those seeking surgical precision without any deformation, it is the ultimate weapon."

Description

The Fortress was designed at the request of the "heavyweight" riders of Lake Annecy, tired of feeling their masts flex under pressure. Its generous chord ensures perfect trajectory stability, while its ultra-thin profile of 13.5 mm guarantees hydrodynamic glide without drag.

Ketos Engineering: Zero Compromise

UHM Technology : The use of Ultra High Modulus carbon fibers allows for an exceptional weight/stiffness ratio.
Controlled Dynamism : Despite its extreme stiffness, the Fortress retains a dynamic "bounce" that facilitates pumping and takeoff in wing.
Modularity : Available in 75, 80, and 85 cm to adapt to all depths and styles of navigation.
