iSUP Center Fin - All-Around Shape

Need a replacement fin or want a spare in case you lose yours?

This 10-inch all-around center fin fits most inflatable paddleboards with Universal or US fin boxes. Includes the thumbscrew and washer for tool-free installation—just hand-tighten and you're ready to paddle.

Why It Works

• 10-inch all-around shape provides good tracking for distance paddling while staying maneuverable enough for turns and general use.
• Fits Universal and US fin boxes so it works with most inflatable paddleboards on the market, not just POP boards.
• Thumbscrew and washer included means you get everything needed for installation. No hunting for hardware or tools.
• Tool-free installation lets you swap fins or reinstall at the beach without carrying a screwdriver in your gear bag.
• Replacement or spare because fins get lost, damaged, or left behind. Having a backup means you're not stuck without one.

The Essential Spare

Fins are easy to lose. You take them off for transport, set them down at the beach, and suddenly they're gone. Or they get damaged on rocks or in shallow water. Having a spare means you're not sidelined when this happens.

The 10-inch all-around shape is the standard size for most recreational paddling. It's long enough to track straight for distance paddling but not so long that it makes the board hard to turn. It's the Goldilocks fin—works for most situations.

The Universal and US fin box compatibility means this fits most inflatable paddleboards. If your board has a standard fin box with thumbscrew attachment, this will work.

The included thumbscrew and washer are crucial. Losing the hardware is just as bad as losing the fin itself. Getting both together means you're actually ready to use it.

Common Questions

Will this fit my inflatable paddleboard?
If your board has a Universal or US fin box with thumbscrew attachment, yes. This is the standard system used on most inflatable SUPs.

Do I need tools to install this?
Nope. The thumbscrew design means you hand-tighten it into the fin box. No screwdriver needed.

What does "all-around shape" mean?
It's a versatile fin design that works for general paddling, fitness, and recreational use. Not specialized for racing or surfing, but good for everything else.

Is 10 inches the right size?
For most recreational paddling, yeah. It's the standard size that provides good tracking without making the board hard to turn. Longer fins are for racing, shorter for surfing.

Will this work on rigid paddleboards?
It can work on rigid boards with Universal or US fin boxes, but most rigid boards use different fin systems. This is primarily designed for inflatable SUPs.
