The 847 is more compact and maneuverable, while the 977 prioritizes glide and stability in downwind and SUP\/prone.\u003c\/p\u003e\n\u003ch3\u003eIs it also suitable for wing foil?\u003c\/h3\u003e\n\u003cp\u003eYes, the Razor 977-375-75 Blackbird performs well in wing foil for downwind and advanced freeride, especially for riders with good technique. For an all-around and easier wing use, foils specifically designed for very early take-off and maximum stability are more suitable.\u003c\/p\u003e\n\u003ch3\u003eWhat type of rider should choose this kit?\u003c\/h3\u003e\n\u003cp\u003eIt is ideal for intermediate–advanced riders who enjoy downwind, pump, and prone surf and are looking for a smooth, responsive, and efficient foil. It is not intended as a first foil for absolute beginners, who benefit from larger and more forgiving wings.\u003c\/p\u003e\n\u003ch3\u003eIs it possible to modify its configuration?\u003c\/h3\u003e\n\u003cp\u003eThe kit is designed as an integrated solution with the 375 stabilizer and 75 Blackbird mast for maximum consistency and rigidity. For those seeking maximum modularity (interchangeable fuselages and stabilizers), there are Razor 977 Blackbird versions with a modular backtail.\u003c\/p\u003e\n\u003ch3\u003eIs it suitable for dock-start and pump-only?\u003c\/h3\u003e\n\u003cp\u003eYes, the combination of surface area, aspect ratio, and 375 stabilizer allows for very efficient pumping for riders with good technique. It is not the easiest choice in the range for first dock-start experiences, but it pays off with great cruising speed and glide.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e```\u003c\/p\u003e","brand":"Sabfoil","offers":[{"title":"953 \/ Integrated","offer_id":61467941077322,"sku":"KR-977-375-75\/BB","price":1899.0,"currency_code":"EUR","in_stock":true},{"title":"953 \/ Modular","offer_id":61467941110090,"sku":"KR977-FCM-SDW375-75\/BB","price":1899.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/3547\/6810\/files\/Screenshot2026-03-31alle18.54.27.jpg?v=1774976151","url":"https:\/\/shop.zzsurf.com\/en\/products\/razor-blackbird-977","provider":"ZZSURF","version":"1.0","type":"link"}
