The present invention is a Low-Drag Fin and Foil System for Surfboards (10), particularly including cambered fin foils (40; 42). The invention (10) also discloses low-drag, directionally unstable fin positions wherein the lesser of negative angle of attack of a trailing fin (50), versus the higher or positive angle of attack of a forward fin (48), makes the board (12) highly maneuverable by creating a yawing moment that aids the rotation of the board (12) as it is turned. The system particularly utilizes fins (40) having foil (42) shapes in which either the cambered side (74) or the non-cambered side (76) is provided with a combination of a convex curvature (68) and a concave curvature (70) to result in an oscillating curvature (72) which has a positive effect on control and acceleration
