Control
Fins control the surfboard, its depth helps it hold in turns, a longer fin base will give you more speed, and a longer rake angle gives tighter turns, additional fins increase these attributes, tight turns especially require fins that are positioned close to the outer edges of the surfboard as a good portion of the bottom will be out of the water, that is why most single fin boards are for cruising or medium wave riding.
