2021 Core SLC Foil Kit

Mast, Fuselage, Mastbase

Engineered to perform

No detail is immaterial. We iterated the smallest details in every component to improve performance and reduce weight.

Package Included

  • 1250 KIT (Naked. incl. 1250cm^2 foil wing, 72cm mast, stabilizer, fuselage, hardward and tool kit)
  • 1000 KIT (Naked. incl. 1000cm^2 foil wing, 91cm mast, stabilizer, fuselage, hardward and tool kit)


Silent. Durable. And light.
Our extruded aluminum mast is almost as light as some carbon ones with the added durability of 6063 aircraft aluminum. And its silent trailing edge design is a welcome relief. New foilers and wave riders should consider the 71cm mast whereas the 92cm mast is our allrounder.

Our extruded aluminum mast features a progressive five stringer, thin wall design that reinforces the highest stress areas. Precise fit tolerances ensure the mast fits tightly into the fuselage.


Hydrodynamic. Efficient. And light.
Our CNC’d fuselage features well-rounded edges to improve water flow over the wing and stabilizer. We’ve maximized the geometric wing connection surface area to reduce twist, improve stiffness, performance, and water flow. We’ve optimized the area between the wing and mast to minimize torsion. The fuselage behind the mast also features a top concave to improve water release. Wing angles are optimized to have a streamlined Fuselage in nominal cruising speeds for extra glide through your turns and maneuvers.

We use anodized 6063 aluminum for strength, durability, and corrosion resistance. Equal length, stainless steel Torx head screws are interchangeable and easier to tighten without damaging the head.

SLC Mastbase. Built to last.

Strong like Ox.
It’s lightweight. It’s 90mm mast track compatible. And its hydrodynamic profile makes a superlative connection to your board. The deep mast socket provides a tight, secure connection with your foil. Its low profile and slick form minimize resistance during touchdowns. We lightweighted the base while adding strategic internal struts to absorb stress from the mast stringers. And we opened the screw attachment points for quicker assembly.
