Katana Construction Carbon Mast with cover

This product is discontinued and will not be restocked.

Inspired by Japanese swordmaking. The strongest carbon mast UniFoil ever built.

The Katana mast borrowed its construction philosophy from traditional Japanese blade forging — an outer layer of extremely stiff high-modulus carbon blended with an intermediate-modulus core for strength. The result was a mast that was super-stiff and fast, with a significantly higher breaking point than pure high-modulus construction alone.

Combined with one-piece construction and a slightly thicker profile than the Race series, the Katana delivered reduced twist and flex under load while remaining one of the fastest carbon masts on the market. The taper-lock mast-to-fuselage connection eliminated play and held the mast securely without relying solely on screws. Slotted holes accepted countersunk titanium hardware for clean fitment, with optional titanium wingnuts for on-the-fly adjustments.

Bolts sold separately.
