Abstract: A kayak ballast system is comprised of a cradle member configured to be fitted within the interior of the kayak. The cradle member defines a receiving unit for securely receiving weight, thereby providing a ready means for adding weight to a kayak and increasing the center of gravity and overall stability of the vessel. The ballast system is used to increase the boats center of gravity in the inventive method. The ballast system may be positioned throughout the interior of the kayak including the forward end of the cockpit and the cargo holds.
