This is a fin with a height and base that are roughly equivalent, combined with a significant rake and a high-performance material construction. This combination is perfect for performance single fins, such as those used in mid-lengths or as the main fin in a 2+1 setup.

Key Performance Summary

This fin will provide a highly responsive, "lively" feel with excellent hold through turns and a powerful projection. It bridges the gap between a locked-in upright fin and a loose, pivotal fin, leaning more towards a "drive and release" style of surfing.

In-Depth Breakdown

1. Rake (44 degrees)

This is the most defining characteristic of this fin. The rake is the angle at which the fin curves backward from its base. At 44 degrees, this is considered a raked template.

• Projection: Raked fins have narrower tips. This allows the tip to more sideways thru the turn. Because it is made of solid fiberglass (see "Material" below), this fin will not change much from its original shape This creates extra speed and projection.

• Carving and Holding a Line: High rake is excellent for drawing long, smooth, carving turns. The fin provides consistent hold throughout the turn because more of its surface area is engaged as the board is put on edge. This prevents the fin from releasing too quickly or "sliding out."

• Reduced PIVOT (Less Loose): The trade-off is pivot. If you are looking for a fin that allows you to make sharp, right-angle, snaps, a 44-degree rake is not ideal. It requires you to set your rail and carve rather than pivot the board over its tail.

2. Height (5.5") and Base (4.85")

The height and base measurements are similar. When you look at the whole fin template, this balance affects how and where it generates its grip and leverage.

• Deep Hold: The 5.5" height provides deep engagement with the water, giving you confidence and stability when you are riding straight and in a trim position.

• Drive (From the Base): A substantial 4.85" base provides a large surface area near the bottom of the board. This is where most of the "drive" (the ability to push against the water to build speed) is generated. This fin will help you generate speed when you are leaning into your rail.

• Tip Sensitivity: While the deep height provides hold, the rake causes the tip to taper. This makes the tip more sensitive and easier to initiate turns than a tall, wide-tipped fin, which would feel cumbersome and overly resistant.

3. Material (Pro Glass / Solid Fiberglass)

The construction material is crucial. "Pro Glass" refers to precision-machined, solid fiberglass panels layered with resin.

• Ultimate Flex Rebound: Fiberglass has a very consistent flex and memory. When it is bent, it wants to return to its original shape instantly. Unlike fins made with honeycomb or carbon, which can have a dampening effect, solid glass feels precise and powerful.

• Lively and Crisp: This material gives the fin a "crisp" and "lively" feeling. Every movement is translated instantly to the water. This, combined with the rake, is what creates that powerful effect out of carves.

• Durability and Weight: Pro Glass fins are incredibly durable, but they are heavier than composites. This extra weight, while minimal, can actually help smooth out some of the inherent chatter from a performance fin, providing a more planted feeling when the water is choppy.

Conclusion: Who is this fin for?

This fin is perfect for a surfer who values precise control and speed generation over raw pivot. It is ideal for open-faced, carving waves where you have the time to set a rail and generate speed.

It would be an excellent choice for:

• Performance Mid-Lengths: As a single fin to give it a more precise, less cruiser-like feel.

• 2+1 Setups: Used as a central fin on a longboard to give it a performance edge, paired with side fins.
