Product Information
Full details
The Deflow Fish Quad is designed for performance-minded surfers who ride swallow-tail quad boards and want a versatile fin setup that bridges the gap between speed-focused drivers and stable, traditional keels. It provides a unique balance of maneuverability and drive for diverse wave conditions, though its rigid, upright design may feel less forgiving to surfers who prefer a looser, more skatey feel in their turns.

FAQs
What board type is this best for?
This set is specifically engineered for swallow-tail quad fish surfboards.
Does the 2/5 flex rating make it hard to turn?
The stiff rating makes the board more responsive and provides more drive, but it does require more technical skill to handle compared to a more flexible fin.
Can I use these on a thruster setup?
No, these are designed specifically as a quad set and will not provide the correct geometry for a thruster configuration.
Are these fins made of fiberglass?
Yes, Deflow uses premium materials consistent with their performance-oriented design philosophy.
How do I know if they fit my board?
Check your surfboard's fin box labels; these fins are intended for standard high-performance quad box systems.
Troubleshooting
Fin feels loose in the fin box
Check that the grub screw is tightened properly or verify that the fin base is fully pushed into the box channel.
Difficulty inserting fin into the box
Ensure no sand or debris is trapped in the fin box and verify you are using the correct box system compatibility.
Pros and Cons
Pros
- Excellent speed-to-stability ratio
- High-quality fiberglass construction
- Precise responsiveness during deep carves
- Tailored specifically for quad fish setups
Cons
- Stiff flex may be too reactive for beginners
- Requires specific quad fin boxes
- Less suited for soft, mushy conditions compared to wider keels
Setup, Compatibility & Care
These fins are designed for standard FCS or Future style boxes (depending on specific production run). Ensure the fins are fully seated in the boxes before tightening the grub screws. Use a standard fin key to secure them, taking care not to overtighten, which can damage the box thread. To care for your fins, rinse them with fresh water after every session to prevent salt crystal buildup, and store them in a protective fin wallet when traveling. Inspect the base periodically for any dings or stress cracks caused by impact with the seafloor or reef.
