A modular keel is arranged along a centerline of a boat hull for displacing a bow wave towards the stern and creating distinct pressure zone situations to draw the keel back into water and reduce pitching. The keel features a base extending along a centerline of the boat hull and two symmetric curved segments. The base tapers toward a vertex on the centerline at a fore transitional area that generates a concentrated high pressure zone to help lift the hull and reduce pitching. The keel includes an aft transitional area for expelling water away from the keel in a laminar flow pattern during forward movement of the boat hull. The keel further includes an intermediate transitional area that creates a low pressure zone to dampen the motion of the hull through waves.
