Patent number: 6122994Abstract: A housing for at least partially housing a boat lift pulley of a boat lift includes a main wall having a substantially vertically disposed wall portion defining an inwardly opening generally concave chamber adapted to at least partially receive therein a boat lift pulley. The main wall includes vertical and horizontal planes disposed substantially normal to each other with the concave chamber being offset to one side of the vertical plane. First and second wall portions of the main wall located at opposite sides of the horizontal plane are adapted for selective removal whereby a gear driven shaft can project therethrough to adapt a housing for selective utilization in either of two positions of installation oriented 180.degree. relative to each other. A peripheral edge portion of the main wall preferably includes symmetrically located fasteners for securing the housing to a companion housing in each of the two positions of 180.degree. oriented installation.Type: GrantFiled: December 9, 1998Date of Patent: September 26, 2000Assignee: Norfolk Fabrication, Inc.Inventors: Lynn P.

Patent number: 5839851Abstract: A lift is provided for a personal watercraft and includes two relatively elongated channel members each of a generally C-shaped transverse cross-section. A carriage carrying a platform upon which the personal watercraft can be supported is mounted for sliding movement between the elongated channel members through a cable, winch, reversible electric drive motor and associated gears and pulleys. When the carriage is located within the upper channel member, the latter, the platform and the personal watercraft can be swung about a vertical axes to rotate the personal watercraft between two different positions 180.degree. removed.Type: GrantFiled: April 22, 1997Date of Patent: November 24, 1998Assignee: Norfolk Fabrication, Inc.Inventors: Lynn P.
