A dock coupler to couple a first dock element to a second dock element includes a first connector having a pin and configured to be coupled to the first dock element, and a second connector configured to be coupled to the second dock element. The second connector includes a rod defining a slot to receive the pin to enable the removable engagement of the first connector to the second connector. The engagement of the second connector and the first connector facilitates a yaw, a pitch, and a roll motion of the second dock element relative to the first dock element.
