Product Review Armstrong Performance Mast

In the world of foiling most of the conversations revolve around the shape and size of the front foil. After that people like to talk about stabilizers, their boards and wing (sail) sizes. The mast does not come up very often and if it comes up then we talk about length. Talking and comparing masts and their performance does actually not come up much and there is not much content on the internet as well.

We got lucky and got to test the Armstrong Performance Mast 865mm. In this video we talk about the difference between the initial 85cm mast and the new Performance 865.

Armstrong Performance 865

The do-it-all length for wing, SUP surf, tow surf, kite, high wind downwind and prone surf.


 “As the sport develops, riders push themselves and the equipment to the limits. After listening to feedback, we wanted to develop a new, innovative, ultra high-performance mast that minimizes drag and ventilation while also being stiffer and even more responsive. – Armie Armstrong

Collaborating with a team of America’s Cup foil engineers, we set out to develop a high performance mast to take us into the future. Our design goal called for a unique blend of strength, stiffness, drag and light weight. Combining CFD analysis with expert insight allowed us to tune each section of the mast from base plate to fuselage connection for maximum efficiency.


Length: 865mm
Weight: 1925g

Includes protective bag and Hardware: 3*M6 28.5mm titanium-plated countersunk head screws + 5*M7 T-nuts + 5*26.4mm M7 316L (titanium-plated countersunk head) CSK Screws + 1*8mm Titanium Barrel nut + 1*S2 naked Zn-Ni coating torx tool. 
Please note that for some 3rd party boards with deeper boxes, you may need to purchase 30mm M7 hardware available on our hardware page.

Structural analysis shows that a combination of both high modulus (HM) and intermediate modulus (IM) carbon fibers best distributes loads throughout various sections of the mast. HM’s stiffness minimizes flex in the mast’s central strut area and IM’s high tensile strength caters to the complex shapes of the top plate and fuselage connection.
