The Fin
The Power Glide 45 is the newest design in True Ames’ continually evolving Greenough collection. This design builds upon many of the same elements found in its predecessor, the Power Blade , yet it has been further refined into a more approachable and user-friendly fin that is ready for a wider range of applications and continued experimentation.
In close collaboration with George Greenough, True Ames modified the outline of the Power Blade into what is now the Power Glide 45, which incorporates more rake, more area, more flex, and softer curves. The ‘45’ in the name of this design refers to the rake which appears as if it is approaching a 45° angle (the actual rake is 32°, which is 9° more than its predecessor). The additional rake in this fin allows for a more generous turning radius as well as a touch more forgiveness overall. Suitably named the 'Power Glide ', this fin will hold its line through larger and smoother arcing turns. In addition to the added rake, this fin also has more overall area than the Power Blade, which will feel a bit more steady and reliable under your feet. Lastly, the Power Glide 45 has a greater amount of flex , resulting in a more responsive and adaptable performance.
Despite its modifications, the Power Glide 45 remains rooted in the same lineage as the Power Blade; as such, it shares many fundamental similarities. One such core element in its design is that it requires the stiffness and performance integrity of an extremely strong ‘leg’ in order to support the enormous load on the ‘head’. Another key factor in its design is the ability of the ‘head’ to twist, as opposed to only flex, like most all other fins. This produces 'variable-tow,' an attribute which allows the fin to twist back and forth and in turn create propulsion based on the angle and direction of attack. Lastly, material selection has resulted in a unique lay-up combination of high-density epoxy and fiberglass materials that have met the strength requirements, without suffering fatigue and breaking down the fibers. Like the Power Blade, the Power Glide 45 meets three distinct demands: stiffness where needed, particular flex characteristics, and the ability to twist.
A direct descendant of continued testing and design revisions, the Power Glide 45 is not meant to replace the Power Blade . It was simply created to serve a larger audience and a wider range of board designs through its additional rake, added area, and increased flex. True Ames continues to push the boundaries and capabilities of single fin designs alongside Greenough and his continual pursuit to find the perfect blend of minimal drag and increased speed together with hyper-sensitive response and maneuverability.
- Designed for boards in the mid-sized range
- Like its predecessor, the Power Blade, it was built to rival the high-performance characteristics of the thruster, while preserving the fluidity and style of a classic single fin
- Relative to the Power Blade, its additional rake, added area, and increased flex make it a bit more adaptable to a larger audience and a wider range of applications
- Proprietary in-house construction made using a blend of heat-treated and bonded high-strength materials

From True Ames
The upper section twists — what True Ames calls variable-tow — so the fin generates its own drive through directional twisting rather than leaning on a multi-fin setup, while the added rake opens the turning radius for longer, smoother arcs.
Our take
Put it on a performance mid-length, edge board, or speed single when you want twist-fin drive and spring without the Power Blade's demands — it holds its line through bigger arcing turns and is more forgiving for everyday surfing. If you surf hard off the rail and want maximum maneuverability, step up to the Power Blade; if you want one fin for many boards, the Greenough 4A is still the benchmark.
More About This Fin
The Power Glide 45 is a True Ames twist fin that evolves the Power Blade template with more rake, more surface area, more flex, and a softer outline. The upper section twists under load, which True Ames calls variable-tow. Construction is heat-treated fiberglass with a high-density epoxy layup. It comes in three sizes, 7.75", 8.25", and 8.75", and is intended for mid-lengths, edge boards, and speed-oriented single fins.

Why Volan?
Volan is a woven fiberglass cloth laid by hand and finished with a resin that cures to a warm amber tint. It flexes differently than solid fiberglass — more spring, more life, more feel through turns. Where solid glass is stiff and direct, volan breathes with the wave.
The hand-laid process means each fin has subtle texture and character. It's heavier, which adds momentum through flat sections. Surfers who ride volan describe it as "warmer" — the fin does more of the work, trimming and holding without demanding constant input.
