A boat lift construction is disclosed for retrieving watercraft from one location and moving them to another location by use of a fixed longitudinal member operatively connected to a winch which moves a carrier frame mounted on wheels back and forth between a first position on land and a second position normally in a lake or river or ocean immediately thereadjacent. This boat lift includes an articulated mounting system for the wheels to facilitate continual contact thereof with respect to the ground during overland movement. The wheels are at least partially hydraulic in order to keep the wheels in contact with the ground surface even when moving in an area below the water line which allows the carrier to move along the overland bottom surface underneath the water line as well as along the ground line immediately thereadjacent.

1. A watercraft retriever lift adapted to move a watercraft overland while directly positioned in abutment with the contour of the land surface located between a first deadman fixed member and a second deadman fixed member comprising:A. a carrier frame means for supporting a watercraft thereon to facilitate moving of the watercraft overland between a first position adjacent the first deadman fixed member and a second position adjacent the second deadman fixed member, said carrier frame means including a first end means and a second end means spatially disposed apart from one another, said first end means being closer than said second end means to the first deadman fixed member and said second end means being closer than said first deadman member to said second deadman fixed member; B. an articulated suspension means attached to said carrier frame means to facilitate ease of movement thereof over the land surface contour between said first deadman fixed member and said second deadman fixed member with a watercraft thereupon, said articulated suspension means including: (1) an articulating arm member pivotally mounted with respect to said carrier frame means and extending longitudinally therealong, said articulating arm member being pivotally movable with respect to said carrier frame means with an axis of rotation oriented laterally with respect thereto; (2) a plurality of axle members mounted in said articulating arm member to be movable therewith with respect to said carrier frame means and extending laterally outwardly therefrom to facilitate movement thereof relative to said carrier frame means to facilitate movement thereof following the land surface contour between said first deadman fixed member and said second deadman fixed member; C. a plurality of wheel means rotatably secured to said axle members of said articulated suspension means to be movable therewith relative to said carrier frame means to facilitate movement of said carrier frame means and a watercraft supported thereon over varying land surface contours between said first dead man fixed member and said second dead man fixed member; D. a continuous longitudinal means attached to said carrier frame means and extending between said first deadman fixed member and said second deadman fixed member to facilitate moving of said carrier frame means therebetween between the first position and the second position, said continuous longitudinal member being attached to said first end means and extending therefrom to attachment to the first deadman fixed member and extending therefrom to attachment to the second deadman fixed member and extending therefrom to attachment to said second end means; and E. a winch means operatively attached to said continuous longitudinal means to urge longitudinal movement thereof to cause movement of said carrier frame means and any watercraft supported thereupon between the first position and the second position, said continuous longitudinal means extending along said carrier frame means without any engagement therewith to freely extend directly from said winch means to said second deadman fixed member to facilitate movement of said carrier frame means relative to said second deadman fixed member as desired.
