7" Height and 7-3/4" Base giving you 44 sq. inch surface area.
This fin is a good flat water condition Sprint fin for low volume older boards like Barks, Kings and Amundson styles. The Stealth Ninja only comes in an Original Fiberglass Structure because it performs with the "S" Flex design which gives you the hold of this 7" fin depth with a faster release feel of a smaller 5 inch fin along with good bottom 1/3 fin surface base area for push to get fast projection. The leading edge sweep of this fin will shed right thru weeds. This fin works with a higher Cadence Paddler around 180-lbs or less. The Stealth Ninja can also be used on Touring boards in Flat water conditions for lighter paddlers. This fin with screw and plate or screwless "Clickit" options only fits boards using a 10" fin box.
