In one aspect the invention provides a boat support frame loading and unloading apparatus configured to draw a boat on to and off a boat support frame. This boat support frame has a loading end and a terminal end opposite to the loading end. The apparatus provided includes at least one roller assembly mounted to the support frame adjacent to the loading end of the support frame, said at least one roller assembly incorporating at least one roller element. The apparatus also includes at least one drive mechanism configured to rotate one or more roller elements to draw a boat onto and off the support frame through the loading end of the support frame. The roller assembly also includes a hull contact surface formed by a flexible belt which has a circumference greater than the circumference of the said at least one roller element incorporated into the roller assembly.

This invention is directed to a watercraft launch and storage assembly including: a mounting assembly; a first step; a watercraft cage pivotally carried by the mounting assembly having a launch position and a storage position; a continuous loop included in the watercraft cage for receiving and surrounding at least a portion of a watercraft; and, a watercraft cage plane defined through the watercraft cage that is generally perpendicular to the waterline when the watercraft cage is in the storage position so that when a watercraft is received by the watercraft cage and in the storage position an angle defined between a plane running through the width of the watercraft and the watercraft cage plane is greater than 90 reducing the amount of water and debris that can enter the watercraft in the storage position.

A watercraft launch for safely launching and retrieving a watercraft in and out of a body of water from an elevated position has a self-adjusting stairway and hull cradle. The watercraft launch is supported for angular movement relative a seawall as the surface of the water moves between different elevations, such as between tides. The self-adjusting stairway has stair treads that move along with the launch in response changing water elevations and adjust to maintain a horizontal position. The hull cradle moveably connected for longitudinal movement along launch between its upper and lower ends.

A boat lift includes two support beams, each beam having each having a rectangular interior space, the top surface of each beam extending beyond the rectangle to provide a flange for connecting components to the support beam; a hydraulic cylinder assembly positioned within the interior of each support beam and including a base and a piston; a fixed pulley block connected to the base and a moveable pulley block attached to the piston; a bunk for supporting a boat, the bunk supported by the two support beams; and two cables extending from opposing ends each of the support beams. The boat lift does not require overhead supports.

A watercraft lift system including one or more laterally-adjustable or rotating components and related methods are disclosed. The watercraft lift system can include a cradle assembly and optionally at least one side guide, which can (but need not) be connected to the cradle assembly. The cradle assembly can include first and second cradle rails. One or both of the first cradle rail and the at least one side guide can be movable between a wider watercraft-receiving position and a narrower watercraft-received position. In an example, movement of the first cradle rail and/or the at least one side guide from the watercraft-receiving position to the watercraft-received position occurs automatically upon entry of a watercraft into the confines of the watercraft lift system. The watercraft lift system can further comprise an actuator to cause lateral or rotational movement, for example, of the first cradle rail and/or the at least one side guide. In an example, the actuator can be operably connected to the first cradle rail and/or the at least one side guide via one or more cables or extension plate members.
