Olo of the Sun 19 foot surfboard , Spitfire cutaway fin

Here's the 13 inch spitfire cutaway fin for the Olo of the Sun taking shape,  when set into the board the tab below the cutaway won't be seen.



The faceted cutaway is a development of the radial cutaways used on previous fins, and is of the type used in 1940's spitfire tailplanes.



Leading edge tubercules will be added next...
