Board Foil Mounts

I am using 2x Dorsal fin 10.5" boxes. They should allow a little movement to adjust the foil position.  
I chose to use the Dorsal Brand boxes as in theory they have a fibre infused plastic which is stronger than the cheaper copies, and they are not exactly expensive, £22 for the pair

As the board is so strong I think it ‘may’ have been ok with these glued and glassed to the surface but I wanted to give it some extra

So I took some inspiration from @blocoloco

And added a short stringer, and reinforced the opposite side too.  
FYI I fully appreciate how neat Blocoloco’s work is compared to mine!

To give some further strength, and tie everything into the skin of the board, the groves and hole for the box were lined with fibreglass mat (so there is glass reinforcement on all sides of the stringers). The mat lining extends out of the groves and over the board surface someway too.

The lined groves are then filled with epoxy, and the ply stringers pushed in, which makes a big old mess!. But not time to clean up just yet. The fin boxes go in the same way, more mess…

I had to stop at this point to tidy a bit so used peel ply to prep the surface for round 2.
