A timeless shape considered an icon in fin design, with enough base for drive while the tapered tip promotes a lively response.
The 4A design is iconic and revered in the world of fin shapes, offering ample base for propulsion and a tapered tip for dynamic maneuverability. This robust fiberglass with a machined finish fin comes complete with the screw and plate for secure installation.
Volan Pro Glass fins have clearly visible fiberglass cloth patterns, reminiscent of traditional Volan fins of the 1960’s.
Here’s some great things about the International 4A fin:
✅ 1. Classic and Timeless Design
Originally designed by George Greenough, the 4A has been a staple for decades.
Its template blends performance and smooth flow, making it ideal for traditional longboarding.
✅ 2. Great for Turns and Flow
The swept-back rake offers smooth, arcing turns.
It provides predictable, fluid rail-to-rail transitions, perfect for trim and carving.
✅ 3. Balanced Flex
The International 4A has a moderate flex, which helps generate speed out of turns.
Offers some spring without being too loose or floppy.
✅ 4. Versatile Performance
Works well in a wide range of conditions – from small, peeling waves to shoulder-high surf.
Can be used in logs, performance longboards, or even mid-lengths depending on the size.
✅ 6. Widely Loved
Highly recommended by surfers across generations.
✅ 7. Ideal for Both Nose Riding and Carving
Offers a good middle ground — enough hold for noserides but loose enough for stylish turns.
Not overly stiff like pivot fins, nor overly loose like flex fins.
If you're building a single-fin quiver or looking to upgrade a longboard setup, the International 4A is a go-to fin for a reason: it just works. Whether you’re cross-stepping, trimming, or drawing stylish lines, the International 4A gives you the confidence and feel to do it all.
