ABSTRACT:
A preferred embodiment of a combination boat lift and dock 10 is described having two spaced pontoons with an intermediate boat support 18. Pivot arm structures 20, 22 pivotally interconnect the boat support 18 with the pontoons. A drive mechanism 24 is connected to the pivot arm structures 20, 22 for pivoting the arm structures downward and inward to move at least one of the pontoons laterally inward toward the other pontoon to raise the boat support to lift a stored boat out of the water. The drive mechanism 24 is also designed to pivot the arm structures upward and outward to move at least one of the pontoons away form the other pontoon to lower the boat support 18 and lowering the boat into the water. The arm structures are pivotally connected to the underside of the pontoons. The dock 10 further includes a pontoon stabilizing mechanism 26 for preventing the pontoons from rocking or tilting.
