This fin slides into the rail glued to the bottom of a Saturn SUP or kayak and locks in with a clip on a string. It’s a direct replacement for the stock fin. Very old fold-and-slide style rails won’t take it without filing down some plastic first.
Specs at a glance
- Fits: Saturn SUPs and kayaks
- Mounting: slide-in rail with clip on a string
- Not compatible: older fold-and-slide rails without modification
Good to know
- Check that your current fin uses a clip on a string; if not, this fin may not fit your rail.
- Keep a spare fin in your kit, since they’re easy to lose in shallow water.
KayakDIY take: A fin is a small part, but a board without one barely tracks. For more options, see my fishing kayak accessories guide.
