4.6" US box center fin Safety Flex Soft replacement for longboard SUP Stand up Paddleboard River Surf Whitewater airSUP AIR7 Skeg

Have bought two of these for two different brands of paddle boards. Fit both boards perfectly. Takes standard screws that you can buy online or any board shop. Use for paddling in shallow lakes with rocks and trees that get closer to the surface as summer goes by and the lakes go lower. Like the size and flexibility of this fin

Works great as a short fin in shallow water. No more superman’ing hitting shallow rocks.

I feel like this is an item that is either 5 stars or no star, it either works or it doesn't. In my case I received a fin that fit my iSUP and worked well. I used on a mellow river float with several shallow gravel bars, the fin flexed and passed through the gravel anytime it struck a bar.

I've yet to use it but so far it looks nice. Arrived unbent and fits my Isle Discovery iSUP. Purchased for paddling at a nearby lake that runs very shallow toward the end of the season. Does have a little bit of wiggle in the fin box but it's not going anywhere. Will update after first use.Update: Tracks fine with my isle inflatable on the lake. Used in the river as well. Had a friend simply go with the 2 fins that are mounted to the board and no center fun, he had a bad day zigging and zagging very slowly upstream where I had a great time staying centered.

I have had mine about 1 year. In that time I have used it on 20+ river trips, most Class 1-2, with countless hits on/drags through gravel in shallows and a few solid hit on rocks after which I was afraid to look at it. It is holding up really well. (Note: while it does have some flex, which probably saves the board from damage, once or twice I have had my SUP stop under me and inertia take over.) I have been able to paddle a few sections with downed trees or snags in creeks where friends with standard fins have had to portage. Would definitely recommend it.

I love the flexibility of the fin. It does not hang on trees or other debris in the river. It does not track quite as straight as my 9" fin but it did pretty well. This fin is a real game change for paddling on the river. It is easily interchangeable with the longer fin for the lake.

Used these on our hard paddleboards to go down 13 miles of the French Broad river and we're so thankful we had them! Hit a few unavoidable rock gardens and these fins held up pretty well but most importantly my fin boxes are still intact! The fins did get a little nicked up but they did a great job of protecting the fin boxes. Kept them on to see how they would track in flat water on the lake and they did amazing! The only time I'll put the 9" fins back on will be for the ocean surf.

I had tried a few other fins for river surfing (SUP boarding on the shallow creeks and rivers in PA), and had snapped a few too many fins in the process. I came across this and on a whim gave it a shot. As a center fin on a thruster set up, it works great - giving just enough flex to not launch you nose first off your board when you do catch something in the shallows, and has yet to scratch, let alone snap off like so many fins before it. One word of caution - make sure you really tighten down the FCS screw on the tail end of the fin attachment because, as it's soft, flexible rubber the whole way through, it can wiggle loose over time. Other than that, I love it and this fin goes everywhere with me! Now, if only they added some side fins to their offerings in the same material, I'd never have to worry about catching a rock...

Bought this to fit to my SUP to take it on a river camping weekend. Did the job and tuck a few knocks as the river was shallow over some rapids but kept me pointing in a straight line which was great as had a few lakes to cross on the trip

Je trouve chère mais bon , pour descendre les rivières devrais fonctionner très bien.

明らかに小波の時、インサイドでのテイクオフの練習に良いかと思い購入。当然とは言え、通常8インチのフィンを一枚で使用している時に比べフィンが底に引っかから無い為、グングン進みます。適度に柔らかいですが斜めに行くレベルでは全く遜色有りませんでした。見た目もお値段以上ですし、工具無しで取付出来るピン付は有り難いのですが前の固定ピンの打ち込み位置が深いのか少しカタカタ動く為、星４つです。

以前の板で頭かち割ったことがあったので買ってみました。正直いいのか悪いのか全くわかりませんがとても柔らかいので気に入ってます。
