I Lost My Original SUP Side Fin — Here’s Why the FunWater 5″ Replacement Saved My Season
If you’ve ever dropped your paddleboard fin in the sand or watched it float away mid-session, I feel your pain. That’s exactly what happened to me a few weeks ago. One moment I was deflating my board after a solid morning session — the next, my side fin had vanished.
I thought I’d be off the water for a while, especially since the original fin came with my board and I assumed replacements would be hard to find or wouldn’t fit. But then I came across the FunWater 5″ Inflatable SUP Side Fin, and let me tell you — it saved my season.
Why I Chose the FunWater 5″ Fin
After doing some research and browsing forums, I found that FunWater’s replacement fins use a universal slide-in base. My board isn’t even a FunWater model — it’s another brand — but as long as the fin box was flat and slide-style (not the grooved U-shaped track), I knew I had a shot.
The price was a no-brainer — under $20, with free shipping. I ordered one and crossed my fingers.
Installation Simple and Fast
When it arrived, I was honestly impressed. It’s made from a tough but flexible nylon material — stiffer than I expected — and it clicked into place with zero drama. No tools, no screws, no cursing at plastic tabs.
It took me 30 seconds to snap it in. That was it. Ready for the water.
Performance: Just Like the Original (Maybe Better)
I’ve now used the replacement fin for several flatwater paddles and one light coastal session, and it’s held up beautifully. The tracking is as good — maybe even a little better — than the OEM fin that came with my board. No sideways drift, and definitely more stable on turns.
What I love most is how durable it feels. I’ve bumped it against rocks in shallow areas a few times, and there’s no cracking or splitting. The flexibility really helps.
Would I Recommend It? 100%
If you’ve lost your original side fin or just want a spare to throw in your dry bag (seriously, do this), the FunWater 5″ side fin is an easy and affordable fix.
It fits well, works just like it should, and doesn’t require any weird modifications. Plus, it arrived quickly and came with decent instructions (not that I needed them).
Losing a fin mid-season sucks — but it doesn’t have to sideline your paddling. The FunWater 5″ side fin is proof that a simple, well-made replacement can get you back on the water fast and affordably.
If you paddle regularly, I’d even suggest grabbing a backup or two. I’ve learned my lesson — never again will I leave the beach without checking that all my gear is accounted for!
