A deployment and recovery assembly for use on a vessel that includes a tiltable ramp section mountable to a vessel to tilt into and out of the water. The ramp section is configured to support the craft. A capture and release assembly that includes a rotatable tire and wheel assembly is mounted to the ramp section to tilt therewith and is disposed on the ramp section so as to engage a hull of the craft. The capture and release assembly further includes a one-way clutch assembly coupled to the tire and wheel assembly allowing free rotation of the tire and wheel assembly in a first direction and retarding or inhibiting rotation in a second direction opposite the first direction.

The boat bunk includes an elongate beam, generally rectangular in cross-section, which beam includes a rigid inner core (1) and a resiliently deformable outer layer or shell (2) covering the core (1). The upper side of the outer layer or shell (2) defines the working surface. The working surface is provided with dome shaped raised protrusions (2a). The inner core (1) is made of unplasticized polyvinyl chloride (UPVC) or hardwood. The inner core (1) is reinforced with metal rods, strips or angled iron strips (7). The outer layer (2) is molded onto the inner core (1). The boat bunk includes fastening means for fastening the boat bunk to a trailer.

A drive-on watercraft (10) has removable/replaceable bunks (50, 80). The bunks are configured to define two rails (64,66; 94a,b). In one embodiment, one rail (64) is higher than the other rail (66). This bunk with rails of different heights can be positioned on the body of the lift with either rail facing inwardly, such that the lift can be configured to receive watercraft of different sizes. In a second embodiment, the bunk (80) has a ramp (84) positioned to extend rearwardly from the back of the lift body when the bunk is mounted to the lift body. The bunk ramp (84) provides a sacrificial point of first contact for of a watercraft with the lift and provides for a softer ride for the watercraft onto the lift.

A winch for moving a load along a track from a first position to a higher position has a drum around which a retrieve and a launch cable are wound in different directions. Rotation of the drum acts to reel in one of the cables while paying out the other. The retrieve cable extends directly between the drum and the near end of the load and the launch cable extends past the rear of the load though a sheave mounted on the track, and then back to far end of the load. A winding mechanism operates in retrieve mode to turn the drum to reel in the retrieve cable and pay out the launch cable. The winding mechanism is used in launch mode to turn the drum in the opposite direction to pay out the retrieve cable and reel in the launch cable. A brake mechanism is operable to halt runaway of the load along and down the track when the winch is being operated in launch mode.
摘要:
A system for automatically launching and recovering marine or underwater vehicles from a carrier ship which remains under way to limit pitching and rolling movements. The system includes an inclinable articulated ramp including a bottom and edges, and hauling means for controlling sliding of the vehicle along the ramp during launch and for hoisting the vehicle up along the ramp during recovery. The ramp has a free end which varies between an immersed position in water and an emerged position in a horizontal position. The system includes buoyancy means allowing the free end of the ramp to float at the surface or near the surface of the water when lowered. The bottom of the articulated ramp also has an external face that is configured to form streamlining ensuring fluidity of the end of the ramp with the water and limiting vertical dynamic movements caused by waves.

A lightweight, knock-down portable watercraft lift or mooring device for small watercraft includes a modular freestanding frame having a pair of spaced supporting foot members, each foot member carrying a pair of spaced support members connected at one end to the foot member, a pair of rails carried by and connected to a second end of the support members. Both the spacing of between the support members and the length of the support members are adjustable allowing the distance between and height of the rails to vary to accommodate watercraft of different widths, water of different depths and create varying lift angles.

An engagement apparatus for use in the deployment and recovery of a marine craft from a mother ship comprises a receptacle provided on one of the marine craft and the mother ship and an engagement probe provided on the other of the marine craft and the mother ship. The receptacle has a number of spaced channels which receive the engagement probe, engagement between the probe and the channels facilitating alignment between the marine craft and the mother ship. A locking device is also provided to secure the probe to the receptacle to secure the marine craft to the mother ship for recovery. The locking device may be activated by full engagement between the probe and the receptacle.
摘要:
A marine craft recovery system for recovering a marine craft to a mother ship comprises a marine craft engagement apparatus and at least a pair of tensile members between the marine craft engagement apparatus and the mother ship. The marine craft engagement apparatus is configured to engage at least a portion of the marine craft, such as the hull. The pair of tensile members is configured to pull the marine craft engagement apparatus towards respective first and second anchor points on the mother ship. The system is configured to transport the marine craft engagement apparatus across a body of water towards the mother ship.

A boatlift for use with small, manual or paddle or oar powered watercraft (such as canoes and kayaks) is provided with a guide rails on either side of the boat lift, which can be utilized by a boater to propel or urge his/her watercraft onto the boatlift. In addition, that boatlift is provided with an entrance/exit assist member which can be used by boaters with impaired leg function to enter and exit from the watercraft. The boatlift can be provided with a bench system which enables disabled persons to more easily enter and exit from small watercraft supported by the boatlift.
