thruster - medium
The YU Techflex , designed by shaper Yoshinori Ueda, is a medium size Speed Contol fin with a Ride Number of 3.5. The Techflex construction and flat foil give this fin a stable feel, making it ideal for controlling speed in more powerful waves. The Yu template features a wide base and refined tip for a good balance of hold and release. The center fin is smaller for increased maneuverability.
