Science Behind Fin Configuration

The well established basics of fin configuration are:
The Rear Fin gives you Stability.
The Side Fins give you Thrust , (Simon Anderson, 1980).

The Fin Cluster
The red triangle represents the fin cluster (how the fins are placed).
The fin cluster is usually set by the shaper, according to the surfer's requirements.
A fin cluster that’s more spread out will create more hold and a larger turning radius.
A fin cluster that’s closer together will create less hold and a tighter turning radius, pivoting quickly.
In general, the fin placement has a great effect on surfboard performance.
What if you could change your fin placement while surfing, in the water with no tools?
