A hitching device permits towing a cargo transport device behind a kayak. The cargo transport device comprises a watertight container and a connection member extending along a longitudinal axis between the container and the watercraft. The connection member includes a swivel such that the container and watercraft on opposite sides of the swivel are freely rotatable about the longitudinal axis relative to one another. This free pivoting allows relative rotation between the container and watercraft such that each can react to outside forces, for example those exerted by waves, independently. As a result, rolling of the container does not tend to induce rolling of the watercraft and so the ride quality of the watercraft is not significantly reduced by the hitching device.
