FIELD OF THE INVENTIONThis invention relates to a customized portable, durable, lightweight device for protecting the hull of a boat from marine growth, algae and invertebrate organisms.
BACKGROUND OF INVENTIONBoat owners often leave their boats floating in water for long periods of time to save time and money.
To transport a boat to and from water usually requires transporting the boat on a boat trailer to a water access point, such as a boat ramp. Alternatively, a boat owner may pay for access to a boat crane to transport the boat onto water. Both of these methods require an investment of time and money. The boat must be transported to a specific water access point that may be a great distance from the boat's docking or mooring point. The boat must be unloaded or unloaded with at least two experienced people. Finally, a boat removed from the water must be stored and often protected from the elements.
To save on resources, boat owners leave their boats floating at their docking or mooring points in the water for long periods of time. However, leaving a boat in the water for a long period of time allows damaging marine organisms to attach to the boat's hull at any water-contacting surfaces. Maintaining the boat's hull from these damaging organisms requires time and money. The boat's hull must be periodically scraped or cleaned of any organisms, and re-painted. This requires removing the boat from the water and transporting it to a painting facility.
Accordingly, a need exists for the long-term protection of the hull of a boat in the water.

However, it is to be expressly understood that such modifications and adaptations are within the spirit and scope of the present invention, and are inclusive, but not limited to the following appended claims as set forth.
As illustrated in
The Keel Case 1 is a totally submersible device that rests beneath the water's surface until a boat 3 is docked or moored above the Keel Case 1. Once the boat 3 is docked, the Keel Case 1 is inflated to form a configuration dimensioned to closely conform to the water-contacting portion of the boat's 3 hull 2. The inflated Keel Case 1 creates a sunlight seal on the hull 2 of the boat 3. Flotation devices on the Keel Case 1 engage the back (stern), sides (port and starboard), and front (bow) of the boat's 3 hull 2 as the Keel Case 1 inflates and the PVC material ascends around the boat's 3 hull 2 to form a seal. Saltwater pumps remove salt water from the Keel Case 1 replace it with fresh water to effectively clean the boat's 3 hull 2 of any debris. Once all of the salt water has been removed, a complete seal on the hull 2 is created. These series of saltwater pumps flush both the hull 2 and engine to protect against the formation of dirt, algae, shellfish (fouling), and the electrolysis. The Keel Case 1 installs in minutes on a dock or mooring and is a customized solution configured upon the make, beam, and length of a boat 3.
A flexible pocket envelope 4 forms the central portion of the Keel Case 1. The pocket envelope 4 is dimensioned to closely conform to the water-contacting portion of the boat's 3 hull 2.
A first plurality of inflatable tubes 5 surrounding the pocket envelope 4 forms the outer portion of the Keel Case 1. The first plurality of tubes 5 is configured to have a corresponding shape to the underwater configuration of the boat 3 hull 2 and propulsion system 15. Each Keel Case 1 is customized in length and width proportional to the size of the boat 3. The corresponding shape of the first plurality of tubes 5 allows the Keel Case 1 to encircle the boat's 3 hull 2 and propulsion system 15 once inflated. The first plurality of tubes 5 form a bow-confirming front portion 7, a stern-conforming rear portion 8, a port-conforming side portion 9 and a starboard-conforming side portion 10 for the Keel Case 1. The port-conforming side portion 9 and the starboard-conforming side portion 10 are substantially parallel with each other. The stern conforming rear portion 8 is substantially perpendicular with both the port-conforming side portion 9 and the starboard-conforming side portion 10.
A second plurality of inflatable tubes 6 are welded or adhered to the pocket envelope 4 of the Keel Case 1 to rigidify and work as stringers. The second plurality of inflatable tubes 6 is substantially parallel with each other and the first plurality of tubes 5.
An inflation hose 11 connects the first and second pluralities of inflatable tubes 5, 6 to an air compressor/vacuum 12 within an external control box 13 for inflation and deflation of the tubes 5, 6. In this embodiment, the inflation hose 11 is attached to the pocket envelope 4 proximate to the stern-conforming portion 8 of the first plurality of tubes 5.
The Keel Case 1 also includes a metal-ballast 14 adhered or welded to the pocket envelope 4 proximate to the bow-conforming portion 7 of the first plurality of inflatable tubes 5. The weight of the metal-ballast 14 causes the Keel Case 1 to sink rapidly underneath the water at the front of the pocket envelope 4 when the Keel Case 1 is deflated.
The Keel Case 1 includes a plurality of mooring adaptor lines 16 that are sewn, adhered, or welded onto an exterior surface of the pocket envelope 4. Each of the mooring adaptor lines 16 encircles the first plurality of inflatable tubes 5.
The Keel Case 1 also includes a bow fixation line 17 that is adjustable upon mooring configuration.
The Keel Case 1 further includes one or more rear lines 18 or rear mooring adaptor lines on the first plurality of tubes 5 on the port-conforming side portion 9 and the starboard-conforming side portion 10 proximate to the stern-confirming portion 8 to help fit the inflated Keel Case 1 to boat's 3 hull 2.
In other embodiments of the subject invention, the Keel Case 1 may have mooring adaptor lines 16 or rear lines 18 attached to various locations on the first plurality of tubes according to the different mooring rules of various marinas and other docking locations.
The Keel Case 1 also includes a metal-ballasted lested water-recovery pocket 19 adhered or welded to the pocket envelope 4 proximate to the stern-conforming portion 8 of the first plurality of inflatable tubes 5. The lested water-recovery pocket 19 is the lowest point of the Keel Case 1 pocket envelope 4. Gravity causes saltwater contained within the Keel Case 1 to flow to the lested water-recovery pocket 19. The pocket envelope 4 is custom made to conform closely to the boat's 3 hull 2 in order to include the lested water recovery pocket 19 at the lowest point near the boat's 3 propulsion system 15.
The Keel Case 1 includes a drain strainer 20 at the bottom of the lested water-recovery pocket 19. A drain hose 21 connects the drain strainer 20 to a water pump 22 in an external control box 13.
The external control box 13 contains a circuit, breaker, a water pump 22, an air compressor 12, and a freshwater inlet valve 23.
The Keel Case 1 further includes a stern rigidifying system 24 to keep the pocket envelope 4 opened at all times. These stern rigidifying system 24 reinforcements of the pocket envelope 4 are located proximate to the stern-conforming portion 8 of the first plurality of tubes 5.
The Keel Case 1 also includes a freshwater hose 25 with a plurality of sprinklers 26 for flushing and cleaning the boat's 3 hull 2 and propulsion system 15 with freshwater.
A deflated Keel Case 1 is placed in the saltwater proximate to a docking or mooring 27. The Keel Case 1 is placed in the saltwater such that it will be underneath the waterline of the docked or moored boat 3.
The Keel Case 1 is installed over a boat's 3 hull 2 in the following manner. First, a deflated Keel Case 1, designed with a configuration dimension to closely conform to the water-contacting portion of the boat's 3 hull 2, is submerged in saltwater at the docking or mooring location of the boat 3. The weight of the metal-ballast 14 of the pocket envelope 4 proximate to the bow-conforming portion 7 of the first plurality of inflatable tubes 5 causes the Keel Case 1 to sink rapidly underneath the saltwater.
Prior to submersion, the inflation hose 11 is attached to the Keel Case 1.
The Keel Case 1 is maintained in a flattened, deflated position in the saltwater by attaching the one or more mooring adaptor lines 16 to the docking or mooring location 27.
The boat 3 is then positioned at the docking or mooring location 27 above the submerged Keel Case 1. The boat 3 is aligned with the submerged Keel Case 1 such that the bow of the boat 3 is aligned with the bow-confirming front portion 7 of the first plurality of tubes 5, the stern of the boat 3 is aligned with the stern-confirming rear portion 8 of the first plurality of tubes 5, the port of the boat 3 is aligned with the port-confirming side portion 9 of the first plurality of tubes 5, and the starboard of the boat 3 is aligned with the starboard-confirming side portion 10 of the first plurality of tubes 5.
Once the boat 3 is aligned with the submerged Keel Case 1, the boat 3 is attached to the docking or mooring location 27. The bow fixation line 17 on the Keel Case 1 is attached to the bow of the boat's 3 hull 2, and the rear lines 18 are attached to the hull 2 of the boat 3.
The boat 3 operator now uses the control box 13 to activate the air compressor 12 to inflate the first and second plurality of tubes 5, 6. The first and second plurality of tubes 5, 6 inflate from the rear of the Keel Case 1 to the front so that the inflated first plurality of tubes 5 closely conform to the water-contacting portion of the boat's 3 hull 2. As the Keel Case 1 inflates, it emerges from the saltwater and lifts the boat 3 off the saltwater surface.
The boat 3 operator then turns on the water pump 22 to remove saltwater from the space between the Keel Case 1 pocket envelope 4 and the water-contacting portion of the boat's 3 hull 2. As this water is removed, the pocket envelope 4 gradually closely conforms to the boat's 3 hull 2 and the propulsion system 15 of the boat 3. Gravity causes any remaining saltwater remaining in the Keel Case 1 to flow to the lested water-recovery pocket 19, which is the lowest point near the boat's 3 propulsion system 15. Once the drainage system removes all the saltwater the water pumps 22 will automatically stop.
The inflated Keel Case 1 forms a configuration dimensioned to closely conform to the water-contacting portion of the boat's 3 hull 2. The inflated Keel Case 1 prevents sunlight from entering the space between the Keel Case 1 and the water-contacting portion of the hull 2 of the boat 3. Preventing sunlight from entering this space prevents microorganisms, algae, and shellfish from engaging in the process of photosynthesis.
In one embodiment of the subject invention, a MIST option may include a fresh water hose 25 attached to a plurality of freshwater sprinkler apertures 26 on the interior surfaces of the first plurality of tubes 5. After the saltwater is removed, freshwater is pumped through the freshwater hose 25 by the water pump 22 through the plurality of sprinkler apertures 26. These freshwater flushes the boat's 3 hull 2 and propulsion system 15 with freshwater.
The process of removing saltwater and flushing the water-contacting portion of the hull 2 of the boat 3 sealed by the Keel Case 1 with freshwater removes dirt, algae, shellfish (fouling) from the hull 2 and prevents further growth saltwater organisms. To remove the Keel Case 1, the boat 3 operator uses the control box 13 to activate the air vacuum 12 to deflate the first and second plurality of tubes 5, 6. The first and second plurality of tubes 5, 6 deflate from the rear of the Keel Case 1 to the front so that the deflated first plurality of tubes 5 disengages the water-contacting portion of the boat's 3 hull 2. As the Keel Case 1 deflates, the case submerges into the saltwater and the boat 3 sinks back into the saltwater surface.
The bow fixation line 17 on the Keel Case 1 is detached from the bow of the boat's 3 hull 2, and the rear lines 18 are detached from the hull 2 of the boat 3. The boat 3 is detached from the docking or mooring location 27 and moved.
