Perfect for rivers in keeping the board on course when a normal skeg would get banged on rocks in shallow sections.

Long shipment but worth it. Indeed it is a long box fit and comes with screw. I used it for a Kahuna 10'10 ISUP. Hit a few rocks and its flex but also holds up. Would be nice to get it in a 2inch.

ビスがノーズ側にあることによりビスの破損によってフィンの先端が岩に引っかかります。ストッパーがテール側についており、脱落しにくいことがかえって危険です。サップインストラクターたちの間では有名なフィンで、すぐにやめたほうがよいとアドバイスされます。クオリティはたかいのでぜひビスをテール側にしたバージョンアップ版を作成してほしいです。

88サーフボードの8ftでのフィンレスサーフィンは難しく、小さなセンターフィンを探してたら、このフィンにたどり着きました。 ボードのボックスが小さく、加工に少々苦労しましたけれど、ソフトフィンで安全性もあり、重宝しています。通常のロングボードではまだ試していませんけれど、スポンジボードにはオススメです。安定性を求めるのではなく、安全性と楽しさに応えてくれるフィンです。耐久性がわからないので星4つです。

I've bought 3 of these over the past year for taking my SUP boards on rivers. They work great for boards with a standard US fin box. One board that looks like it does, but actually is non-standard, is the Starboard 4-in-1 inflatable. Its box is slightly shorter and has a fixed socket for the fastening bolt. Happily, I was able to trim this fin's "nose" to fit using a Dremel tool, and to drill a new hole for the bolt. Works like a charm now.
