Aileron central à verrouillage rapide SUP

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.

This fin fit like a glove, true to size and compatible with Costco HYPER paddle board.

I contacted Hyperlite about replacement fin (horrible construction when fin slide back, falls off and drown) but got no response.Found this fin with similar shape and it fits!I did small modification (drill a hole and put a safety wire on clip attached to the sup) and hopefully will not loose it again.

Love it! This fin fit my IROCKER board perfectly.
It also improved the tracking substantially.

I was glad to see you had one in stock. I'm guessing I didn't lock my fin in correctly and lost the center fin. I have not used the new one yet, but it does look like the correct fin. The fin came quickly and the boards we purchased years ago are working great. Thanks.
