A bunk for a boat lift includes a bottom portion pivotally configured to attach to one or more lifting beams of the boat lift. A top portion is positionably securable to the bottom portion wherein the top portion comprises includes a boat engaging surface having a first end and a second end wherein the first end is a first distance from a midplane of the top portion and the second end is a second distance from the midplane of the top portion. The top portion is positionable into a first position where the boat engaging surface is in a first position relative to the bottom portion and wherein the top portion is positionable into a second position by moving the top portion end for end relative to the bottom portion wherein boat engaging surface is a second position relative to the bottom portion.

Boat transfer system (10;110) on a floating vessel (30), comprising at least one deployment frame (14;114) for deployment of a cradle (12), wherein said deployment frame (14;114) is movable in a mainly horizontal direction and the deployment frame (14;114) is equipped with upright guides (18;118) for vertical movement of the cradle (12), and said cradle (12) is connected to a guide system (22;130,132,134) for controlled movement of the cradle (12) in the upright guides (18;118).

A system and apparatus for dockside or waterside kayak launching, entry and exit along with stabilization, storage and transportation elements. In addition to the storage and transportation benefits, the kayak system as shown and described herein allows a user to easily remove and store a kayak from the water to a non-use position. The kayak system and apparatus generally includes a main frame generally having a 90 degree bend wherein the main frame is configured to pivot so as to allow lifting and lowering of the kayak to and from the water.

A shiplift includes a pier defining a space. The pier includes lifting apparatus. The shiplift includes a shiplift platform configured to fit within the space defined by the pier. One or more movable connectors are mechanically coupled to the shiplift platform. Each movable connector is configured to move into at least two positions, including a first position and a second position. In the first position, the movable connectors are mechanically coupled to the shiplift platform and positioned to allow the shiplift platform to enter the space defined by the pier. In the second position, the movable connectors are mechanically coupled to the shiplift platform and positioned to mechanically couple to the lifting apparatus of the pier.

This invention relates to a loading mechanism, including a first roller assembly and second roller assembly, at least one mounting for the first and second roller assemblies, wherein the first roller assembly and second roller assembly each have a longitudinal axis, a drive mechanism configured to rotate the first roller assembly and second roller assembly, so as to move an object, wherein as the weight of the object applies pressure to at least one of the first and second roller assemblies the mounting allows the roller assemblies to move so as to change the angle between the longitudinal axis of the first and second roller assemblies.

A hydraulic ship lift, including: a mechanical synchronizing system; a stabilizing and equalizing hydraulic driving system; and a self-feedback stabilizing system. The stabilizing and equalizing hydraulic driving system includes first resistance equalizing members arranged at corners of branch water pipes or/and second resistance equalizing members arranged at bifurcated pipes, circular forced ventilating mechanisms arranged at front of water delivery valves of a water delivery main pipe, and pressure-stabilizing and vibration-reducing boxes arranged behind the water delivery valves. The self-feedback stabilizing system includes a plurality of guide wheels; each guide wheel of the self-feedback stabilizing system is fixed on a ship reception chamber through a supporting mechanism. The supporting mechanism includes a base connected to the ship reception chamber, a support articulated on the base, a flexible member fixedly arranged between the support and the base, and a limiting stopper arranged on the outer side of the flexible member.

A watercraft bunk assembly includes a lower base that is secured to a support post of a boat lift or other boat supporting structure. A separate upper base is slidably interengaged with the lower base. The upper base is configured to carry a cushion component at an angular inclination for engaging and supporting a boat or other watercraft. Various upper bases having different respective configurations may be interchangeably engaged with the lower base, which enables the bunk assembly to be used for supporting a number of different types of boats and hull configurations.
