Naish SUP Fins

SUP fin compatibility guide

Which Fin Fits My Naish SUP?

Naish is a premium SUP brand with a lineup built for everything from all-round paddling to open-water touring, and every inflatable board we track — Crossover, ONE, Glide Air, Alana and Maliko — uses a standard US Box fin. That's the most widely supported fin system on the market, so any correctly sized US Box replacement fin from Eisbach Riders will fit your Naish board. The main decision isn't compatibility — it's picking the right fin for how you paddle: a shorter, more maneuverable fin for the all-round Alana, or a longer touring fin for distance-focused boards like the Maliko or Glide Air. Select your model below to see our recommendation.

Which Fin System Does Your Board Use?

Not Sure Which Model You Have?

  • The model name is usually printed on the rail or near the tail.
  • Board length in feet is usually printed on the nose or deck.
  • Production year is sometimes printed near the fin box on newer boards.
  • The fin-box shape tells you the system: a raised box with a screw is US Box, a soft molded fin is Fixed/iFin, and side-by-side clip slots are Quick-Lock.

Popular Model Families

Crossover iSUP
Fin system: US Box
Recommended replacement: Classic Fin 9″

The Crossover is Naish's do-everything all-round board and runs a standard US Box fin, consistent across model years. It's built to handle flatwater, small surf and everything between, so our Classic Fin 9″ — a manoeuvrable all-round shape — is the fin we'd recommend for it.

Glide Air (12'0, 12'6)
Fin system: US Box
Recommended replacement: Touring Fin 9″

Glide Air is Naish's distance-touring board and shares the same US Box fin box as the Crossover, so fit isn't a concern — only fin shape is. Our Touring Fin 9″ is built for straighter tracking on open water, which suits how most Glide Air owners paddle.

Check These 4 Things Before Ordering

1
Board model
Confirm your exact model — ranges within the same brand can use different fin systems.
2
Fin system
Identify whether your board uses US Box, Quick-Lock, Slide-In, or a fixed Fixed/iFin.
3
Fin-box condition
Check the box or track isn't worn or damaged before fitting a new fin.
4
Model year
Some brands have changed fin systems across generations — check when your model changed if you're unsure.

Frequently asked questions

What fin box does Naish use on its inflatable SUPs?
US Box, across every model we track — Crossover, ONE, Glide Air, Alana and Maliko. It's the industry's most widely supported system.
Which fin fits a Naish Maliko?
The Maliko is a longer, touring-focused board with a US Box fin. A longer, stiffer touring fin will give you better tracking on distance paddles than a shorter all-round fin.
Is the Naish Alana fin the same as other Naish boards?
The fin box is the same US Box system across the range, but the Alana is built for all-round paddling, so a shorter, more maneuverable fin usually suits it better than the longer fins used on touring boards.
