Its reworked section shape is a stiffer evolution of our industry-leading PM Mk I. Now with a 13.8mm thickness, chord refinement, and an even more efficient profile. Bending stiffness has been boosted by 30%, with torsional stiffness up 20% over the Mk I, delivering sharper feedback and rock-solid confidence at speed. Whether you’re downwinding, throwing freestyle, or laying into powered turns, this is the mast that will do it all.\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv data-content=\"description\" class=\"tab-switch__content\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Armstrong","offers":[{"title":"722","offer_id":55550181376376,"sku":null,"price":1499.0,"currency_code":"GBP","in_stock":true},{"title":"795","offer_id":55550181507448,"sku":null,"price":1549.0,"currency_code":"GBP","in_stock":true},{"title":"865","offer_id":55550181638520,"sku":null,"price":1599.0,"currency_code":"GBP","in_stock":true},{"title":"935","offer_id":55550376608120,"sku":null,"price":1639.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/1388\/0748\/files\/Screenshot2026-05-08at11.28.27.png?v=1778236171","url":"https:\/\/poseidon-watersports.com\/products\/armstrong-mk-ii-performance-carbon-mast","provider":"POSEIDON","version":"1.0","type":"link"}
