Collaborating with a team of America’s Cup foil engineers, Armstrong set out to develop a high performance mast to take you into the future. Their design goal called for a unique blend of strength, stiffness, drag and light weight. Combining CFD analysis with expert insight allowed Armstrong to tune each section of the mast from baseplate to fuselage connection for maximum efficiency.
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.
The result is a top of the line mast consisting of top shelf materials, new mast section, refined baseplate, reduced drag fuselage connection and new construction method. Proprietary titanium M7 mast top hardware follows suit with a strong, light and drag reducing connection to the board.
They tested over 100 prototypes to come up with the latest performance mast.
These masts are designed with a mast rake angle. This fine tunes the board angle relative to the foil for a more comfortable and forgiving ride. It does not change the lifting force or balance of the foil itself, and it does not impact the foil’s “foot pressure” bias front or back.
Board rocker also directly determines effective mast rake – boards from different brands have a variety of different rocker lines which influence rake angle – and more rocker in the rear half of board effectively increases mast rake. The 1 degree of rake we’ve placed specifically into the top of the Performance Mast shape provides three main benefits by adjusting the board relative to the foil underwater:
Simply put, the Performance Mast range takes the sublime Armstrong feeling further than ever.

★★★★★YvetteThe team at Stonker is not only hardworking but also lovely. My experience with Jess and Ben was truly exceptional as they possess extensive knowledge about their products. Despite I was interstate, I communicated with them over the phone and received exemplary assistance. I am extremely satisfied with their services and highly recommend Stonker to others. I will certainly be a returning customer in the future.
