• T1 Twin fins/Keel fins are a classic twin-fin setup best known for creating a smooth, drive-filled surfing experience.
• .Keel fins are incredibly versatile but are most famously associated with specific board types. They are primarily designed for twin-fin setups and are a great match for: Fish surfboard, Funboards / Mid-Lengths surfboards; Modern Twin-Fins & Grovelers boards: Many modern board designs are specifically crafted to be used with keel fins, adding a performance edge to small-wave boards.
• If you want to make your board feel fast, smooth and locked, and focus on carving powerful lines, keel fin is the perfect choice. Optional small trailer fins can be installed to improve stability and drive bottom and top turns, making the circuit board feel closer to the thruster (three-fin setting) without sacrificing all the looseness of the wings. When riding as a double fin (no trailer), the fin provides a classic, loose and smooth track-to-track feeling. .
