Every millimetre was designed to give the rider the very best experience possible, turning an everyday session into something special. The design was developed with Armstrong's America's Cup foil design partners. The goal called for a unique blend of strength, stiffness, minimal drag and light weight. Combining CFD analysis with expert insight and the feedback of key team riders resulted in every section of the mast from top plate to fuselage connection being designed for maximum efficiency and the best feel possible.\u003c\/p\u003e\n\u003cp\u003eManufactured with premium Toray intermediate and high-modulus carbon fibre.

Armstrong's modular A+ System has set the industry standard for foil compatibility — front wings, masts, fuselages and stabilisers all interconnect across the Armstrong range, meaning riders can progress from S1 (Step 1) beginner foils through to HA (High Aspect) racing foils without replacing their mast or board fittings. Built in Thailand at Armstrong's own facility, designed in New Zealand, ridden by world-class athletes including Austin Tovey, Noah Flegel and Annie Reickert.\u003c\/p\u003e\n\u003cp\u003eMôr Watersports is an authorised Armstrong dealer in North Wales — we hold stock, offer demo sessions where conditions allow, and ship across the UK with free postage.\u003c\/p\u003e\n\n\u003cp\u003eFree UK postage. \u003cstrong\u003e01492 588001\u003c\/strong\u003e to discuss whether the Mk I, Mk II or Performance-X is the right premium-carbon mast for your foiling.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"655","offer_id":55565024592248,"sku":"SD_03187","price":1299.0,"currency_code":"GBP","in_stock":false},{"title":"725","offer_id":55565024625016,"sku":"SD_05452","price":1349.0,"currency_code":"GBP","in_stock":true},{"title":"795","offer_id":55565024657784,"sku":"SD_05342","price":1399.0,"currency_code":"GBP","in_stock":false},{"title":"865","offer_id":55565024690552,"sku":"SD_05985","price":1449.0,"currency_code":"GBP","in_stock":false},{"title":"935","offer_id":55565024723320,"sku":"SD_05963","price":1499.0,"currency_code":"GBP","in_stock":true},{"title":"1035","offer_id":55565024756088,"sku":"SD_02185","price":1549.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/0653\/4457\/files\/Armstrong-PM795-01.jpg?v=1779189278","url":"https:\/\/morwatersports.com\/products\/armstrong-performance-carbon-mast-mk-i","provider":"Môr Watersports","version":"1.0","type":"link"}
