Title: Combination boat and distressed boat flotation apparatus and related methods

Description:
FIELD OF THE INVENTION  
       [0001] The present invention relates to the boat industry and, more particularly, to the field of boat protective devices and methods.  
       BACKGROUND OF THE INVENTION  
       [0002] In the boat industry, over the years, boats, and particularly boat hulls, have been damaged by rocks, sand bars, storms, fires, poor construction, and various other reasons. The result is often a distressed boat out in the middle of a body of water such as an ocean, a sea, a lake, or river. The crew or passengers of a distressed boat may have an emergency kit or equipment such as life jackets, flares, rafts, food rations, radio equipment, or the like to assist in initiating distress signals to the Coast Guard, other agencies, or potential rescuers. The emergency equipment may allow crew or passengers to be rescued if rescue personnel arrive in time. The rescue personnel, however, often are not able to help or rescue the boat itself. Also, the damage to the hull of the boat often causes the boat to sink and often with boating equipment, crew, and passengers on the boat. Even if crew or passengers are not hurt, the boat itself and the boating equipment often can be quite expensive and can be a severe loss for the owner as well as insurance companies. Unless treasure or some other extraordinarily expensive equipment is on the boat, the costs associated with trying to raise the boat from the depth of a body of water are often prohibitive.  
       SUMMARY OF THE INVENTION  
       [0003] With the foregoing in mind, the present invention advantageously provides a combination boat and distressed boat flotation apparatus, a distressed boat flotation apparatus, and methods of installing and using a boat flotation apparatus which prevents a boat from sinking so that the boat and crew or passengers can be rescued more effectively. The present invention also advantageously provides a combination boat and distressed boat flotation apparatus, a distressed boat flotation apparatus, and methods of installing and using a boat flotation apparatus which saves the expense of a complete loss of a boat and assist in reducing insurance costs associated with expensive boats and equipment sinking. The present invention also advantageously provides a combination boat and distressed boat flotation apparatus, a distressed boat flotation apparatus, and methods of installing and using a boat flotation apparatus which enhances locating a distressed boat, assists crew and passengers on the distressed boat in notifying rescue personnel of the distressed condition, and assists crew and passengers in surviving while waiting until rescue personnel arrive.  
       [0004] More particularly, the present invention provides a combined boat and distressed boat flotation apparatus which preferably has a boat including a boat hull having an outer surface and an inner surface and a plurality of flotation containers positioned to substantially surround the boat hull when inflated with a gas responsive to the boat hull being in a distressed condition so that the boat is prevented from sinking by the inflated plurality of flotation containers. The distressed condition preferably is defined by water passing through the outer surface of the boat hull into contact with the inner surface of the boat hull when the boat is positioned in a body of water or the boat capsizing. The combination also preferably includes a plurality of spaced-apart moisture sensors each embedded in the boat hull to sense the distressed condition and a distressed condition controller positioned in communication with the plurality of moisture sensors and the plurality of flotation containers to control the inflation of the plurality of flotation containers responsive to at least one of the plurality of moisture sensors sensing the distressed condition.  
       [0005] The present invention also provides a distressed boat flotation apparatus which preferably includes a plurality of flotation containers adapted to be positioned to substantially surround a boat hull of a boat when inflated with a gas responsive to the boat hull being in a distressed condition so that the boat is prevented from sinking by the inflated plurality of flotation containers. The distressed condition preferably is defined when water passes through the outer surface of the boat hull into contact with the inner surface of the boat hull when the boat is positioned in a body of water or the boat being capsized. The apparatus also preferably includes a plurality of spaced-apart moisture sensors each embedded in the boat hull to sense the distressed condition and a distressed condition controller positioned in communication with the plurality of moisture sensors and the plurality of flotation containers to control the inflation of the plurality of flotation containers responsive to at least one of the plurality of moisture sensors sensing the distressed condition.  
       [0006] The present invention additionally provides a method of installing a boat flotation apparatus on a boat. The method preferably includes positioning a plurality of moisture sensors within a boat hull of a boat and positioning a plurality of flotation containers to substantially surround the boat hull when inflated.  
       [0007] Another method of preventing a boat from sinking responsive to damage to the hull of the boat according to the present invention preferably includes sensing water passing through the boat hull and inflating a plurality of flotation containers positioned to substantially surround the boat hull when inflated and to float the boat therewith thereby preventing sinking of the boat.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
     [0019] The present invention will now be described more fully hereinafter with reference to the accompanying drawings which illustrate preferred embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout, the prime notation, if used, indicates similar elements in alternative embodiments.  
     [0020] FIGS.  1 - 6  illustrate a combined boat and distressed boat flotation apparatus according to the present invention which preferably has a boat  10  including a boat hull  12  having an outer surface  13  and an inner surface  14  and a distressed boat flotation apparatus  20  preferably including a plurality of flotation containers  25 , e.g., air bags or other containers which can be quickly inflated as understood by those skilled in the art, positioned to substantially surround the boat hull  12  when inflated with a gas responsive to the boat hull  12  being in a distressed condition so that the boat  10  is prevented from sinking by the inflated plurality of flotation containers  25 . The distressed condition preferably is defined by water passing through the outer surface  13  of the boat hull  12  into contact with the inner surface  14  of the boat hull  12  when the boat  10  is positioned in a body of water. Each of the plurality of flotation containers  25  preferably is formed of a puncture resistant and fire-resistant material as understood by those skilled in the art. The distressed condition can also be defined by the boat  10  being capsized, i.e., turned over so that the boat hull  12  is out of the water and a passenger compartment is in the water. The plurality of moisture sensors  30  also preferably includes boat capsizing sensors embedded in the boat hull  12  and in communication with the distressed condition controller to control the inflation of the plurality of flotation containers responsive to the boat capsizing sensor. The boat capsizing sensor can be provided by a level, for example, that detects the position of the boat on the horizon and inflates the plurality of flotation containers  25  responsive to a predetermined level of the boat on the horizon, i.e., if the level indicates that the boat is turned over, then the flotation containers  25  are inflated to prevent the boat  11  from sinking.  
     [0021] The distressed boat flotation apparatus  20  individually and of the combination also preferably includes a plurality of moisture sensors  30  each embedded in the boat hull  12  to sense the distressed condition and a distressed condition controller  35  positioned in communication with the plurality of moisture sensors  30  and the plurality of flotation containers  25  to control the inflation of the plurality of flotation containers  25  responsive to at least one of the plurality of moisture sensors  30  sensing the distressed condition. More specifically, the moisture sensors  30  are embedded between the outer  13  and inner  14  surfaces of the boat hull  12  so that if there exists a breach in the integrity of the outer surface of the boat hull  13 , i.e., water seeping through a crack in the outer surface of the boat hull  13 , the moisture sensors  30  are activated and the plurality of flotation containers are inflated to substantially surround the boat and prevent it from sinking.  
     [0022] The apparatus  20  can also include a plurality of lights  28  each associated with a respective one of the plurality of flotation containers  25 . Each of the plurality of lights  28  preferably is responsive to the respective one of the plurality of flotation containers  25  being inflated during the distressed condition. Each of the plurality of lights  28  also preferably include a moisture sensor associated therewith. Each of the plurality of lights are therefore also preferably responsive to the moisture sensors. In other words, after the flotation containers have been inflated and the lights connected thereto contact moisture, the lights will be activated. The lights may be flourescent lights, strobe lights, or any other type of lights to draw attention to the distressed boat as understood by those skilled in the art. Also, a solar-powered, global positioning device  40 , e.g., GPS device as understood by those skilled in the art, preferably is positioned associated with the boat  10 , e.g., mounted to a control panel in the boat, in or adjacent the flotation containers  25 , or in or adjacent the hull  12 , in communication with the distressed condition controller  35 , and in communication with a satellite communication system to communicate the location of the boat  10  when in the distressed condition. This is advantageous in that it allows rescuers to readily locate the boat in the distressed condition in cases where no other communication is possible with persons stranded on the distressed boat.  
     [0023] Additionally, the apparatus  20  can advantageously include a boat occupant shelter  45  associated with the plurality of inflated flotation containers  25  to shelter boat occupants from damaging weather conditions, e.g., sun, wind, rain, or cold weather, during the distressed condition. The boat occupant shelter  45  preferably has at least one sheet  46 , and more preferably a plurality of sheets  46  or other structures to form a tent, a covering, or other shelter, formed of a fabric material and positioned to connect to and extend between at least two of the plurality of inflated flotation containers  25  so that boat occupants can underlie the at least one sheet  46  and thereby be protected from damaging weather conditions.  
     [0024] The apparatus  20  can further advantageously include a water purification device  50  associated with the boat  10  to purify water for boat occupants during the distressed condition. The water purification device  50  preferably includes a water desalinater  52  to desalinate salt water for drinking by boat occupants during the distressed condition. The water desalinater  52  preferably has a salt water intake  53  positioned to intake salt water, a salt water purifier  55  positioned in fluid communication with the salt water intake  53  to remove salt from the intake salt water, e.g., from the ocean, and a purified water output  54  positioned in fluid communication with the salt water purifier  55  to output purified water to boat occupants during the distressed condition.  
     [0025] As illustrated in the drawings and as described above, the present invention additionally provides a method of installing a boat flotation apparatus  20  on a boat  10 . The method preferably includes embedding a plurality of moisture sensors  30  within a boat hull  12  of a boat  10  and positioning a plurality of flotation containers  25  to substantially surround the boat hull  12  when inflated. The plurality of flotation containers  25  are positioned in communication with the plurality of moisture sensors  30 . The method can also include positioning a distressed condition controller  35  in communication with the plurality of moisture sensors  30  and the plurality of flotation containers  25  to control inflation of the flotation containers  25  responsive to the sensing of a distressed condition. The distressed condition preferably includes the sensing of water passing through the boat hull  12  or the boat capsizing. The embedding of the plurality of moisture sensors  25  preferably includes forming a plurality of recesses  16  in an inner surface  14  of a boat hull  12 , inserting a respective one of the plurality of moisture sensors  25  in a respective one of the plurality of recesses  16 , and covering each one of the respective plurality of moisture sensors  25  so that each one of the respective plurality of moisture sensors  25  are embedded between the inner surface  14  of the boat hull and the outer surface  13  of the boat hull. The embedding of the plurality of moisture sensors  25  also can include embedding each of the plurality of moisture sensors  25  between an inner surface  14  and an outer surface  13  of a boat hull  12 .  
     [0026] Also according to the present invention, a method of preventing a boat  10  from sinking responsive to damage to the hull  12  of the boat  10  is provided which preferably includes sensing water passing through the boat hull  12  and inflating a plurality of flotation containers  25  positioned to substantially surround the boat hull  12  when inflated and to float the boat  10  therewith, thereby preventing sinking of the boat  10 . The method can also include indicating the location of the floating boat  10  to rescue personnel. The step of indicating can include communicating to a satellite the location of the floating boat  10  and/or illuminating lights  28  associated with the floating boat  10 .
