The DW Performance Series, already proven under the feet of team rider Oskar Johansson at the 2023 Molokai2Oahu World Championship, is tailored for SUP Downwind experts seeking the next level of open-water freedom.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThe product of cutting-edge hydrodynamics and foil technology. \u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eProject development began with collecting waveform and real-world riding data from the inter-island channels of Hawaii to establish specific design parameters. Leading Computational Fluid Dynamics (CFD) resources helped optimize an airfoil shape that offers extreme glide at the top end with achievable flying speeds at the low end for race starts in milder conditions. The result is remarkably stable at high speeds.\u003cbr\u003e\u003cbr\u003e\"These foils have a speed range like no other I've ridden. They have a low enough stall speed to get on the foil, but then an incredibly high top speed that allows you to ride the fast waves in the open ocean. The foils also have very neutral front and back foot pressure that doesn't change with different speeds, which gives a comfortable feel at high speeds.\" - Oskar Johansson, Armstrong Team Rider and 2nd place at Molokai2Oahu 2023\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eState of the Art\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eOur Performance Series represents the pinnacle of Armstrong Foiling equipment.

A hexagonal carbon fiber fuselage with a titanium rod core has progressive flex characteristics that balance stiffness with a uniquely soft feel underfoot. This construction minimizes the flex caused by the extreme torsional forces generated by the foil's front wing and stabilizer. High-quality 316 stainless steel and titanium hardware practically eliminate corrosion and ensure a natural, precise fit. On the stabilizer, polycarbonate Pro Shims allow for incremental half-degree changes in pitch, enabling incredibly easy tuning of the foil's flight characteristics.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eDWP 685\u003cbr\u003eArea: 685cm2\u003cbr\u003eSpan: 960mm\u003cbr\u003eAspect Ratio: 13.55\u003cbr\u003e\u003cbr\u003eDWP 755\u003cbr\u003eArea: 755cm2\u003cbr\u003eSpan: 1000mm\u003cbr\u003eAspect Ratio: 13\u003cbr\u003e\u003cbr\u003eDWP 930\u003cbr\u003eArea: 930cm2\u003cbr\u003eSpan: 1100mm\u003cbr\u003eAspect Ratio: 13\u003c\/p\u003e","brand":"Armstrong Foils","offers":[{"title":"755","offer_id":57158134301054,"sku":"SSF15853.1","price":969.0,"currency_code":"EUR","in_stock":false},{"title":"930","offer_id":57158134268286,"sku":"SSF15853.2","price":1019.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/9188\/5438\/files\/DW.jpg?v=1774322513","url":"https:\/\/www.surfshopfehmarn.de\/en\/products\/armstrong-foils-downwind-performance","provider":"surfshopfehmarn","version":"1.0","type":"link"}
