Abstract: A combination boat trailer and lift includes an elongated base frame with forward and rear ends, a hitch assembly and an axle and wheel assembly to facilitate towing behind an automobile over land. An elongated, collapsible upper frame having front and back ends is cooperatively coupled to the base frame through a plurality of spaced apart elongated coupling arms, each arm of which is pivotally attached at one end to the base frame and at its other end to the upper frame. The upper frame is longitudinally and vertically displaceable with respect to the base frame in a pivotal mode on the coupling arms between an extreme lowered position and an extreme raised position such that the rearwardmost displacement of the upper frame corresponds to the extreme lowered position and forward movement of the upper frame from its extreme lowered position moves the upper frame toward its extreme raised position. A winch and cable system draws the upper frame at least toward its extreme raised position.
