'Jet' 7'8" pintail wooden surfboard

Here's the cutaway spitfire fin for the 7'8" 'Jet' being foiled today. The fin is 6 laminations of 3mm Paulownia.The 4 inch diameter tunnel fin will sit neatly inside the cutaway. My hand represents the bottom of the surfboardChord ratios will be 15% on the base, and 8% just above the cutaway. The complete fin system is 9 inches high and 9 inches long ( fore and aft ). It is a very powerful setup.
