These fit perfectly! We have 4 HL paddle boards from Costco and have lost 2 fins. The original fin that came with the board is 10in L by 6 1/4 w by 5/16in thick and this replacement is 8 1/4in L by 6 1/4in W by 5/16in thick. So yes, the replacement is a few inches shorter but it’s doesn’t affect movement in the water. I’m just happy I found this replacement fin, it locks right in and does exactly what it’s supposed to do.

I was nervous when I ordered this piece because I wasn’t sure about the measurements, but it fit perfect! Excellent quality!

I was thrilled that this fit my Costco Hyper/Lite perfectly. It was easy to insert and remove. I’ve only used it twice so far but all seems well. Most important to me was finding a fin that fit, as the first one i purchased was too wide to insert and lock into place.

Center fin not compatible with IRocker board. Very close but doesn’t quite snap in.

Our three year old threw the original fin overboard 🫡 this replacement fin fits the Costco hyperlite paddle board perfectly! Very happy with this purchase

I was pessimistic since irocker cruiser side fins are diversified to the point where it seems unlikely anything will simply fit, yet this mofo did and appears to look good. Maybe there is more movement in this fin, I will come back and revisit this review if some drawback presents itself but it is looking awesome at present.

Lost an original fin and of course they are out of stock on irockers site. Luckily these side fins fit perfectly in my ultra board and they also aren’t as long as the ones that come with the board which is a huge bonus. They don’t have the string lock hole but they clipped in and worked great.

As I now know, because I've obsessively been looking on the internet for a replacement for my SUP all week, this type of fin is known as 'quick lock' or 'easy fit' or 'snap lock' or by any of a number of slightly different names. Why this 'snap lock' business is considered to be a better arrangement of fin that the type that screws properly and securely to the bottom of your SUP I can't imagine, but for some reason they do seem popular. They're also prone to being shed from the SUP like autumn leaves in my limited experience so I can't say I'm much of a fan. I suspect that most SUP boards that use these fins have a standard-sized fin box meaning the fins are interchangeable. This doesn't apply to the blinkin' TigerXBang Defender however, and that, unfortunately, is the type I've got. It's a great board otherwise, just difficult to get spare parts for. Anyway. This Thurso Surf centre fin was about....7mm definitely too long for the TigerXBang. This was a great fin, seems really sturdy, it's very reasonably priced and it came next day delivery. It's just a shame I've no use for it on the TigerXBang SUP because it's too big, so it had to go back. The returns and refund process was painless though. I just wish it fit.
