The Front Mount Boatlift mounts to the front of your dock with two dock brackets. These brackets hold the front of the frame in place with solid steel circular pivots and allow the back of the boat lift to lower. The two side brackets that are attached to the side of the dock support the lift when it is in the down position. This leaves the boat lift in a slant position with the back of the lift submerged underwater, basically just like a trailer backed down a ramp. You then drive your boat up the lift just like a trailer backed into the water. The polymer cradles in normal applications hold your boat in place while you let the blower motor raise your boat along with the steel frame completely out of the water. The side brackets that stop your lift from going down too far are solid hot dipped galvanized steel and mounted to your docks inner frame. When the lift is in the upright position the side brackets which now look like a capital "T," are actually applying up pressure to your dock. With your boat lift locked in the upright position you are virtually adding extra floatation to your dock and combining your boat lift and dock as one. This makes the Front Mount Boatlift the ultimate boat lift for rough water because your boat lift and boat will only move as much as your dock does in rough water. Capacities are ranked to the back of the lift's bunk system, if your boat hangs off further than the lift due to its length you might need to purchase larger lift capacities in order to lift your boat.
