This fin would work great for a paddle board but beware of using it for a surfing. I wanted to try dropping down from a 10 inch fin on my 9β6β this past month and it worked great until I rode my last wave of the session into shallow water and it snapped when I grazed the sand. I didnβt βgroundβ the board, just took a low tide roller in to finish the day and hopped off the board in about a foot deep water. The water temp was 35 degrees so maybe the cold had something to do with it but…cheap plastic was most likely the culprit. It broke right at the flange for the thumb screw, bummer. Not sure what I should expect from such a cheap fin but for a SUP it should work great which is why I gave it three stars. Donβt plan to get years of use from this fin as durability has proven to be an issue. But, for a backup or a way to try out a different fin size before committing to a higher end fiberglass fin, this works just fine.

Hunted high and low for a center fin for a used C4 Waterman, 10′ 6″ SUP that I bought without fins.Couldn’t find anything that told me it would fit and the C4 site sucked royally without any info either.This fin fit well though I did have to file down the two brass pegs at the back of the fin base in order to fit the track inside the fin box. After that, it fit perfectly.The fin looks good and I’m confident it will do the job well.The fin came quickly…I’m a happy camper

I have a Bic Performer 10’6″ board, and this fin is a direct match for a replacement fin part. Easy to install on my board, firm grip in the track using the provided screw, solid construction, really polite customer service email immediately after the sale, super cooled company website with lots of information, and I’m so glad to have found this replacement part. Looking forward to getting back out on the water post-lockdown to test it out but it seems like it will be Surfs Up then!

This fin was a good replacement for my lost Atoll iSUP fin at a fraction of the price. Iβve used it for most of the summer now, and itβs held up. It has the same issue of being held in place with a screw as the original, but as long as you donβt skip that step, itβs easy to install.
