True Ames Greenough Power Glide 45 Single Fin

Epoxy/Fiberglass Composite Single Fin

The Power Glide 45 is a high-performance single fin designed for mid-length surfboards. Developed in collaboration with George Greenough, this fin builds on the foundation of the earlier Power Blade model, with a refined outline, increased rake, more surface area, and added flex for broader compatibility and smoother performance.

With an actual rake of 32°, the Power Glide 45 features a more drawn-out profile than its predecessor. The added rake allows for longer, more controlled turning arcs and greater forgiveness, especially in larger, more open-faced waves. The increased surface area contributes to greater stability and tracking, while the enhanced flex pattern supports dynamic response and smoother transitions through turns.

Like the Power Blade, the Power Glide 45 is built around a rigid base designed to support the significant mechanical load on the upper portion of the fin. The upper section—or "head"—of the fin is engineered to not only flex but also twist, enabling what Greenough refers to as "variable-tow." This function allows the fin to generate drive through directional twisting, contributing to propulsion, speed, and control without relying on multiple fins.

The construction consists of a proprietary layup of bonded, heat-treated fiberglass and high-density epoxy, specifically selected for long-term flex integrity and resistance to fatigue. This approach ensures the fin maintains consistent performance under stress without breaking down over time.

The Power Glide 45 offers a blend of high-performance capability and single-fin fluidity, designed for riders who want the responsiveness of modern setups while preserving the style and feel of classic single-fin surfing.
