Axis Foil Mast KAIWI Ultra High Modulus

Kaiwi is a pure-performance mast designed to minimize drag in the water and maximize glide during downwind racing, pump foiling, and prone foiling. After more than a year of development, the mast has already proven its capabilities through top finishes at international competitions in all three disciplines.

By optimizing the mast for foil wings with a smaller span and lighter riders, Kaiwihas achieved an exceptionally low drag profile that larger, stiffer masts simply cannot match. It is designed for foil wings with a span of up to 100 cm and for riders weighing 85 kg or less. The result is an uncompromising mast for those seeking maximum efficiency, minimal drag, and the highest possible performance.

Through extensive analysis of both hydrodynamics and structural loads, the development team has optimized every detail of the mast’s geometry and material stiffness. What began as a project to create the world’s most efficient mast for downwind racing quickly proved to have a significantly broader range of applications.

Its exceptional efficiency makes the Kaiwi an attractive choice for all foil riders seeking less drag, better glide, and increased control—provided the rider falls within the recommended weight limit and uses foil wings with a span of less than 100 cm.
