How surfboard fins different base and depth effect?

I see nowadays many types of fins have different base and depth on their side fins and center fins, I want to know what happens when your side fins base longer then center fins? depth on side longer then center? or center fin longer depth or base then side fins? I hope someone can explain this, thanks !!!

I almost had a stroke reading your question but im going to infer that you are talking about future fins. The center fins are always 1/2inch deep and the side find are always 3/4inch deep. This is because of the Finboxes used and how future system works. The center finbox is shallower because on a very thin tail, it would end up too close to the deck if it where the same depth as the side boxes. you also had a question about the deeper base but im not sure I understand that one.
