Molded in durable materials and finished with drag-reducing wing texture and subtle ghosted graphics, this foil improves acceleration, helps keep the bow down sooner, and minimizes common handling issues like chinewalking and cavitation. Installation is straightforward and secure, and the unit is manufactured in the USA.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this hydrofoil affect acceleration and getting on plane?\u003c\/h3\u003e\n\u003cp\u003eThe Classic Senior 2 creates additional lift behind the motor, reducing the time and throttle needed to reach plane. Boats accelerate more efficiently, which shortens launch distances and improves driver sightlines because the bow responds sooner.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned lift profile for quicker plane initiation\u003c\/li\u003e\n  \u003cli\u003eWorks across boat types and hull shapes within engine range\u003c\/li\u003e\n  \u003cli\u003eReduces engine strain during hole shots\u003c\/li\u003e\n  \u003cli\u003eOften lowers throttle needs for similar speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it stabilize porpoising, chinewalking, or ventilation?\u003c\/h3\u003e\n\u003cp\u003eThe foil is engineered to dampen oscillation and prevent airflow or water intake under the prop, addressing porpoising and ventilation while curbing chinewalking.

The STINGRAY HYDROFOILS Classic Senior 2 suits owners of boats running 40–300 hp outboard or outdrive motors who want faster plane times, steadier handling, and fewer disruptions from common cavitation or porpoising problems. It’s ideal for recreational boaters who tow tubes or skiers, anglers wanting a more predictable ride, and anyone seeking a durable, USA-made stabilizer that installs reliably and reduces everyday operating costs.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What engine sizes fit the Classic Senior 2?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Fits outboard and outdrive engines rated between 40 and 300 horsepower.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does installation require drilling?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — slide the foil on, mark holes, and drill the cavitation plate for the 4-bolt permanent mounting.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"STINGRAY HYDROFOILS","offers":[{"title":"Default Title","offer_id":48030518739105,"sku":"B0B69GVPZ7","price":188.51,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0758\/6532\/5729\/files\/stingray-hydrofoils-front-profile.jpg?v=1791404213","url":"https:\/\/canadiansporting.ca\/products\/stingray-hydrofoils-classic-senior-2-hydrofoils-for-1","provider":"Canadian Sporting","version":"1.0","type":"link"}
