Default Twin fins help early planning?

I was wandering if placing fins just below the rails would help to keep the flow under the board, not leting it escape to sides. Because all the flow which escape to sides don't contribute to lift but only to friction.
Without making calculations I expect that it wouldn't be efficient, but anyway I think is an interesting fenomenon to study.
Merry Christmas!

Can somebody tell me where to manage my account? Were are my private messages?
