The race fins on the raceboards are foils too, they are just positioned more vertical.
During the race, they actually create enough force to skim on the surface of the water.

A race board with over 2m square of board hitting the water all the time is NOT more efficient than a foil.

This is how it's done.
Look at the cavitation wake, coming off the back of your fins , (there almost is None) .
Now look behind your board about 5-8 ft and notice the rather Large amount
of turbulence on the surface of the water ; then tell us all, what were gonna figure
was the reason your board got up in the air ? -------------------------------------it bounced.
If you want ME to believe what your saying, then show the Same shot without
that turbulence behind the board and i'll believe it.

... With long enough fins, the raceboard would levitate like a foilboard
I Totally See that ; i just looked at the angle of your fins again, as there "Just" slightly
tilted towards down-wind, which would LIFT the board.
You Don't need another shot ; i believe you now.
Perhaps that is the reason WHY they made that rule ?

Fins on a raceboard can be up to 50cm. Most people run three fins from 35 - 40cm. There's still a lot of development that could happen in raceboard fins.
