Indiana SUP Fins

SUP fin compatibility guide

Which Fin Fits My Indiana SUP?

Indiana is one of the most popular SUP brands across the DACH region, and every inflatable model we track — the 10'6 Allround Family and Wave, the 11'6 Touring and Touring Lite, the 12'6 Touring and Race, the 14'0 Ocean Race, and the Feather Light series — uses a standard US Box fin. That's good news: a US Box replacement fin from Eisbach Riders fits correctly across the entire Indiana range, so you don't need to hunt for a brand-specific part. What changes between models is the ideal fin shape — the shorter Allround boards suit a manoeuvrable all-round fin, while the 14'0 Ocean Race and Touring/Race boards benefit from a longer touring fin for straighter tracking. Pick your exact model below.

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

10'6 Allround Family / Wave
Fin system: US Box
Recommended replacement: Classic Fin 9″

Indiana's 10'6 Allround Family and Wave boards are the brand's entry point for everyday paddling and use a standard US Box fin. Box dimensions haven't changed across model years, so a replacement fits an older board just as well as a new one. Our Classic Fin 9″ suits the manoeuvrable, all-round paddling these boards are built for.

11'6 Touring / Touring Lite
Fin system: US Box
Recommended replacement: Touring Fin 9″

The 11'6 Touring and Touring Lite share the same US Box fin box as the rest of the Indiana range. These are distance-focused boards, so our Touring Fin 9″ — built for straighter tracking — is the fin we'd point you toward, especially if you're upgrading from the stock fin.

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

Does every Indiana SUP use the same fin box?
Yes — every model we track, from the 10'6 Allround Family to the 14'0 Ocean Race, uses a US Box fin. Only the ideal fin shape changes depending on the board.
What fin should I get for an Indiana 14'0 Ocean Race?
The Ocean Race is a long-distance racing board, so a longer, stiffer touring fin in a US Box will give you noticeably better tracking than a short all-round fin.
Is the Indiana Feather Light range fin-compatible with the rest of the lineup?
Yes. The Feather Light series uses the same US Box fin box as Indiana's standard boards, so the same replacement fins fit.
