yup...
A Formula Board helps you get on the foil quickly and the width provides the leverage over the rig....
They are perfect for foil boards....

Have you reinforced the fin box or are they strong enough already

I personally have not bothered and have had zero issues but according to some of the top guys it is completely random. Some boards are for me and others break within a few hours I guess better safe than sorry. The major pressure is on the front of the fin box (bottom of the board). I was considering a small flap on the front of the fin to help spread the load instead of going to all the effort of reenforcing the whole box? Not sure it that is a realistic option though?

I'm on an original iSonic 121L 75cm wise board with no reinforcing.

I'm using a 2nd hand Fanatic Formula Ti with no problems so far (but I've only been out 3 times so far).

I'm also using a Slingshot foil with their "2018 SLINGSHOT HOVER GLIDE TUTTLE CONNECTOR" which spreads the load over the bottom of the board, similar to what Brett was suggesting above.
