Morning.
I'm looking for a power box fin approx 10.5 inches long 265cm etc. Let me know what you may have thanks. Snapped mine at canton last Friday. Must have hot something.
Surfsail WA have both types in approx. 10.5"(27cm) sizes in the MFC range: www.surfsailaustralia.com.au/products/Windsurfing-Fins/Maui-Fin-Company#surf-sail-clothing-hardware
