FIELD OF THE INVENTION

The present invention relates to marine safety aquatic devices, and, more particularly, to Water Rescue or Life Protecting Apparatus (US Class #441/80).

BACKGROUND OF THE INVENTION

Description of the Related Art

Marine Crew Overboard situations have repeatedly proven themselves to be a matter of life or death. Many boats built today have no proper form of safe egress from the water, especially when the sea is rough. Even a healthy, active person is usually incapable of getting back into the boat over the high freeboard of today's craft. Water temperature, even relatively warm water, will render the COB unable to even perform the most rudimentary actions to help themselves in a very short time. In the case when the larger of the crew falls overboard and their children, wife, or husband is in the water, no help from the crew in the boat is enough to get the COB back in the boat. COB's have literally drowned during the efforts of the crew to get them back aboard. Many times the COB is injured when falling overboard or is incapable of helping in their own rescue. For a person in the boat to lift a 200 lb+ COB over the freeboard and back into the boat is beyond the possibility of almost any boater. Many COB victims die, even after the boat is successfully brought alongside, as there is no way to get them back aboard.
It is quite common for recreational boaters to not wear a flotation device, regardless of whether flotation devices are available on the boat. Additionally, many boaters have limited or no swimming skills and if such a person goes overboard, even in the calmest of conditions, the threat of drowning is immediate.
Very few boaters practice COB recovery techniques, and as a result, have no clear idea of what to do when this situation occurs. The wind and sea state that often help create the COB situation will further complicate the situation. Very few boaters practice handling their craft in heavy weather conditions and high wind and waves can make the crews movement or actions aboard the boat very difficult. Even a Licensed Captain and well seasoned crew will find difficulty handling the vessel and maneuvering aboard the boat during this time. Current training methods of Crew Overboard Rescue techniques do not cover a technique for a small untrained person is to bring a large injured person back aboard. Currently there are no approved or even effective equipment or methods for doing this. The training is inadequate, because the equipment has not yet been invented for the final critical step of getting the COB out of the water and back aboard.
In a typical COB rescue attempt a lot of confusion and poor boat handling by a panicked crew trying to perform a poorly practiced maneuver will ensue. However, the boat is usually brought alongside the COB close enough for a line to be thrown to them and they are hauled alongside. Getting the COB back into the boat is where the system breaks down. With high wind and waves, there is very little time before the boat begins to drift and the waves make movement aboard very difficult.
While the Skipper of a boat may have adequate training, he/she are most likely to become the COB. If the Skipper falls overboard during routine boating tasks, the most he can be hope for is that his poorly trained crew bring the boat alongside him. The situation is further exacerbated when there is only one poorly untrained crew left aboard. Once alongside, they still have to get the skipper back aboard. A few simple directions from the skipper in the water to explain the mounting system for the Crew Overboard Rescue Hoist will easily allow a small untrained person to quickly bring him back aboard. This can be done by a small crew member through the mechanical advantage of the Winch.
A sling or flotation collar attached to a line are commonly used for COB rescue. The sling is thrown in the vicinity of the COB1, or thrown in the water and then maneuvered toward the COB. When the COB is attached to this sling there is still the question of how to lift a heavy waterlogged COB from the water over the vessels freeboard to get them back into the boat. In the current State of The Art there is no viable system for the majority of boats on the water.
Calling for help from one of the Government or private agencies which perform these rescue attempts, means a long delay before they arrive. In most cases, waiting for this rescue agency is not an option. The person in the water may not survive this wait. Especially in a rough or cold water situation.
The current state of the Crew Overboard rescue art does not have a system which can be used on any small vessel, by a single, small, poorly trained, crew member, in difficult conditions. They should be able to use this system to lift a much larger, heavier, COB from the water and deposit them into the boat. This system needs to be light, small, portable, affordable, have adequate mechanical lifting advantage, and be easily and quickly deployed. The COBRH meets all of these needs.

SUMMARY OF THE INVENTION

The present invention provides a Crew Overboard Rescue Hoist which can be used to safely and quickly retrieve an overboard crew member in difficult conditions, even when done by a small crew member with a minimum of training and expertise, which is affordable, lightweight, small, portable, and easily stored.
The invention comprises, in one form thereof, a Crew Overboard Rescue Hoist for retrieving an object in the water including a hoist and platform to slide the COB vertically up out of the water and deposit them into the boat. A line connected to the platform winch and a webbing loop connected to the line used to encircle the COB, keep them attached to the line and raise them into the boat.
The invention comprises, in another form thereof, a method of retrieving an object in the water, including the steps of: providing a crew overboard rescue system including a platform, a line connected to the winch mounted on that platform at one end and a webbing loop connected to the other end; connecting the line to the slide is a hand crank used to raise the object; deploying the crew overboard rescue system on the side of the boat; encircling the object in the water with the webbing loop; and lifting the object from the water utilizing the hand crank; and depositing them/it into the boat.
An advantage of the present invention is that a COB rescue can be performed by a small untrained person lifting a large injured person up out of the water and depositing them into the boat.
Another advantage of the present invention is that a COB can be rescued safely in difficult conditions including high seas and/or strong winds.
Yet another advantage of the present invention is that a COB can be rescued safely when the COB is unconscious and/or injured.
A further advantage of the present invention is that a COB can be rescued safely by a small untrained person alone.
A further advantage of the present invention is that an COB can be rescued safely without the need for precise positioning of the boat relative to the COB.
A further advantage of the present invention is that it is relatively easy to deploy and use.
A further advantage of the present invention is that it is relatively inexpensive.
A further advantage of the present invention is that it will be easy and inexpensive to maintain, repair and keep ready for deployment.
A further advantage of the present invention is that it can be quickly deployed.
A further advantage of the present invention is that it can quickly and efficiently lift a COB from the water and deposit them into a vessel with no other lifting apparatus necessary.
Yet another advantage of the present invention is that it can rescue a COB without the need to put a rescue swimmer in the water.
Yet another advantage of the present invention is that it can retrieve other heavy floating objects from the water.
Yet another advantage of the present invention is that it can be attached to other structures (Docks, Piers, Wharves, etc.) and be used to lift people or objects from the water and back onto the structure to which it is attached.

DETAILED DESCRIPTION OF THE INVENTION

Rescue Hoist Parts and Assembly and Manufacture

1) The entire COBRH will be painted in accordance with the international “O” or “Oscar” flag (Red on top and Yellow on bottom painted on a diagonal where the two colors meet (this also facilitates a low friction lifting surface)
2) The bottom section of the COBRH is 17″×18″×¾″ and must be built of very stiff material

The bottom section has two footholds cut out of it to allow a healthy COB to climb
The bottom section is attached to the middle section using very strong hinge(s) attached to the front of the COBRH
The top of the bottom section is cut at a 15 degree angle so that it rests against bottom of the middle section at a 15 degree angle from the horizontal

3) The middle section of the COBRH is 17″×36″×¾″ and must be built of very stiff material

It is attached to the top section with very strong hinge(s) attached to the front of the COBRH
There are two footholds cut from this section to facilitate the COB to climb while being lifted
There is a strong bar of steel (Keyhole Bar) attached (thru-bolted) to the back at the top of this section. It is rotated and attached to the top section using the keyhole attachment
There are two 2″ webbing straps attached near the top back side of the middle section.
These are for attaching to the keyholes on the inside of the gunwale

4) The top section of the COBRH is 17″×30″×¾″ and must be made of a very strong material

A winch for hoisting the COB back aboard is mounted on the back of the right hand side of this top section near the shoulder level of the rescuer
There are two pulleys mounted on the back of this section that directs the hoisting line from the winch on the side of the COBRH to the top center of the COBRH
The top section has a cutout for the operator to place his/her hand while cranking the winch and raising the COB aboard.
The bottom back of this section has a bolt head sticking out to attach the Swiveling Keyhole Bar. This locks the upper section of the COBRH in an open position

The top center of the top section has a pulley recessed into the unit with a line fairlead that keeps the Hoisting Line inside the pulley and centered on the front of the unit.

One end of the hoisting line is attached to the drum of the winch. It then runs through the two fairlead pulleys thence to the top center pulley of the Rescue Hoist. This causes the hoisting line to run from the back to the front of the COBRH.

Attached to the end of the Hoisting Line is a sling which is used to encircle and raise the COB. It is 6″ wide and 55″ long and made of stiffened Polypropylene so that it has some buoyant force when deployed.

The line will also be made of polypropylene so it will float when deployed

The length of each section of the COBRH can be changed to accommodate a specific vessels freeboard height
