SBS - 9 inch Longboard & SUP Single Fin - 9" Center Fin for Surfboard & Paddleboard (Black)

I haven't surfed on it yet but this was better than a similar competitors that needed to be sanded to fit. I've never had a plastic fin before, only plexiglass, so no idea if it will perform yet. But it passed the fit test and was easy to install. Bonus it had a cover.

Lost my Isle original fin, got this replacement and it works great! Really happy with the purchase and it seems more secure than the original fin.

Review only from the perspective a nonstandard use. I'm sure it is great for its intended application as well. I needed a replacement fin for a Perception Hi Life 11ft hybrid that was outright missing its fin. This size of SBS fin is an exact fit in terms of the hole for the thumbscrew, the 'foot' part of the base, base width and length, and general fitment in the fin box. What does not match, if you're wanting to use it for a Hi Life, is the supplied thumbscrew. What comes with this fin is a M4x0.7 screw and nut, and a high-quality set at that. What the Hi Life's body-mount nut needs however is a 10-32. Additionally, the Hi Life's fin box is slightly too short for where the supplied nut requires it to be situated in the fin box. This slight misfit is due to the inside angle of the box housing, which obstructs the new nut from fitting directly below the thumbscrew hole. Thus to make the SBS fin work with the supplied nut and screw, you're either boring a new hole a little bit back from where the Hi Life built-in nut is situated, or you're supplying your own 10-32 thumbscrew and using the Hi Life's body-mount nut. Either way would work and let you enjoy this nice fin. Again, this is an admittedly nonstandard use for a great fin, and I'm very happy to have found this product. I used a 10-32x0.75" screw with a small stainless washer topped with a small rubber washer to hold the metal washer onto the screw. This worked great for a couple hours of testing on a choppy lake, and on another outing for a 5-mile adventure in mixed conditions. The screw I chose to use keeps this from being a tool-less solution, but it beats the heck out of the alternatives if obtaining a replacement Hi Life fin is slow. To summarize in case anyone else is wanting to find a Perception Hi Life 11ft hybrid kayak replacement fin: this fin itself fits perfectly in the Hi Life, and in fact it could be the same one that comes with the Hi Life. What's different is the thumbscrew; to secure the fin with no drilling, you will need to supply either a new 10-32 screw (appx thread length 3/4") or use the thumbscrew that presumably came with your Hi Life. In the latter case, this fin is an exact fit. In the former, it's up to you to locate a thumbscrew you like, and a washer. The washer is appropriate to keep the thumbscrew (or screw head) from damaging the plastic shoulder of the Hi Life fin box.

This fin was a good replacement for my lost Atoll iSUP fin at a fraction of the price. I’ve used it for most of the summer now, and it’s held up. It has the same issue of being held in place with a screw as the original, but as long as you don’t skip that step, it’s easy to install.

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!

Pretty bummed to have to send this back. Do not consider "specifications" the measurements to determine the fit.

Bought a Pau Hana EZ Angler display model from LL Bean's Fishing Store and assumed the staff had tightened down the fin. Well after the first day of use I was minus one 9 inch fin. Tried to swap over my Rave lake cruiser fin but switching out hardware and fin every time was inefficient so bought this fin and it works fine. The real reason why it is a good purchase is that it comes with its own hardware sized for use with the fin which makes it universal for any board. Wish they would not bubble wrap the hardware in its own little tiny bubble wrap baggie ... I actually threw out the hardware accidentally because it blends in with the rest of the bubble wrap packaging ... and I threw it out even though I had seen it inside but had forgotten all about it. Thankfully retrieved.

We had the misfortune of losing the hardware to attach the original fin that came with our paddleboard. We tried a makeshift attachment system, but one day it failed and the original fin is now somewhere at the bottom of the lake. Found this replacement at Amazon and it has saved our board! Obviously you can't steer without a fin. This one came with the attachment hardware which was SUPER easy to install. We are now looking forward to a summer of paddleboard fun! Kristi at Santa Barbara Surfing has been very attentive too in making sure that the product has met our needs. Should a problem arise with it in the future I have no doubt that they would work hard to resolve the problem.
