Best Conditions: Everyday surf conditions
Skill Level: Suitable for beginners through to advanced surfers
A 6.75" Pro Glass fin with a 5" base and 44° rake is a classic powerhouse template, typically utilized in mid-lengths, performance longboards, or as a substantial "hatchet" style center fin in 2+1 setups.
Because it is constructed from Pro Glass (solid fiberglass), the performance is defined by its structural memory and high-tension flex.
Key Performance Characteristics
1. Exceptional Drive and Projection
With a 5" base, this fin has a significant amount of surface area anchored at the board’s rail/stringer line.
2. "Drawn-Out" Arcs (The Rake Factor)
The 44° rake is quite pronounced. This moves the "tip" of the fin well behind the base.
The Result: The board will naturally want to pull into long, smooth, carving turns. It resists "pivoting" on a dime, making it ideal for high-speed down-the-line surfing where stability and flow are prioritized over vertical snaps.
3. Solid Fiberglass (Pro Glass) Flex Pattern
Unlike honeycomb or carbon-fused fins, Pro Glass is dense and uniform.
The Load: As you load up a turn, the fin flexes gradually along its height.
The Release: Because fiberglass has a slower, more "dampened" spring-back than carbon, the transition between turns feels buttery and predictable. It absorbs "chatter" in choppy water, providing a dampened, high-fidelity feel.
4. Tip Release and Hold
The height of 6.75" provides enough leverage to keep the tail engaged in steeper faces, but the sweep allows the tip to "release" at the end of a turn. This prevents the board from feeling "tracky" or getting stuck in a straight line.
Ideal Conditions & Setups
Best For: Point breaks, open-face reef breaks, and clean swells where you have room to wrap a long turn.
Board Match: * Mid-lengths (6'8" – 8'0"): Use as a single fin for a pure, flowing experience.
User Feel: It will feel "planted." If you are coming from a plastic or composite fin, the first thing you will notice is how much more speed you maintain through your cutbacks.
Summary: This is a "driver’s fin." It rewards a surfer who uses their rails and looks for flow, offering a predictable, high-speed rail-to-rail transition without any of the "skittishness" found in lighter, more upright fins.
