Submersible boat

Abstract

A submersible boat is provided which utilizes a planing boat hull with a sharp bow and blunt stern. The submersible boat performs as a planing boat until it nears the target location. Then, the boat submerges in order to avoid detection. After this vessel submerges, it travels with the blunt end forward and the sharp end aft.

What is claimed is: 
     
       1. A vessel which can operate both as a planing boat and as a submarine comprising: a blunt end of said vessel,   an outboard motor located near said blunt end of said vessel,   a pointed end of said vessel,   a propeller located near said pointed end of said vessel,   wherein said outboard motor propels said vessel with said pointed end forward as said vessel moves at planing speeds,   wherein said propeller propels said vessel with said blunt end forward when said vessel operates as a submarine,   a rudder located near said pointed end of said vessel,   wherein said rudder steers said vessel when said propeller propels said vessel,   a plurality of bow planes,   a plurality of stern planes,   wherein, the pressure of the water flowing over and under said bow planes and said stern planes steers said vessel as said vessel submerges and ascends,   a plurality of open ballast tanks, and   a plurality of closed ballast tanks,   wherein, movement of water into and out of said open ballast tanks and said closed ballast tanks changes the weight of said vessel.   
     
     
       2. A vessel which can operate both as a planing boat and as a submarine comprising: a blunt end of said vessel,   a pointed end of said vessel,   a propeller located near said pointed end of said vessel for propelling said vessel with said blunt end forward when said vessel operates as a submarine,   an outboard motor located at said blunt end of said vessel for propelling said vessel with said pointed end forward when said vessel operates as a planing boat,   a plurality of bow planes,   a plurality of stern planes,   wherein, the pressure of the water flowing over and under said bow planes and said stern planes steers said vessel in the desired direction,   a plurality of open ballast tanks,   a plurality of closed ballast tanks,   wherein, movement of water into and out of said open ballast tanks and said closed ballast tanks changes the weight of said vessel, and   a rudder located near said pointed end of said vessel,   wherein, said rudder steers said vessel when said propeller propels said vessel.   
     
     
       3. The vessel of claim 2 further comprising a foam core top constructed of a glass fiber material. 
     
     
       4. The vessel of claim 3 further comprising a plurality of hatches in said foam core top, wherein, the passengers and the crew of said vessel can enter said vessel through said hatches. .Iadd.   
     
     
       5.  A vessel which can operate both as a planing boat and as a submarine, comprising: opposed blunt and pointed ends of said vessel;   first propulsion means mounted to said vessel near said blunt end for propelling said vessel in a first forward direction of operation defined by said pointed end being forward when said vessel operates as a planing boat;   second propulsion means located near said pointed end for propelling said vessel in a second forward direction of operation defined by said blunt end being forward when said vessel operates as a submarine;   means mounted to said vessel for steering said vessel when said vessel moves with said blunt end forward or said pointed end forward; and   means mounted to said vessel for ballasting said vessel. .Iaddend..Iadd.6. A vessel which can operate both as a planing boat and as a submarine, comprising:   opposed blunt and pointed ends of said vessel;   propulsion means mounted to said vessel for propelling said vessel in a first forward direction of operation defined by said pointed end being forward as said vessel operates as a planing boat and for propelling said vessel in a second forward direction of operation defined by said blunt end being forward when said vessel operates as a submarine;   means mounted to said vessel for steering said vessel when said vessel moves with said blunt end forward or said pointed end forward; and   means mounted to said vessel for ballasting said vessel. .Iaddend..Iadd.7. A vessel which can operate both as a planing boat and as a submarine, comprising:   opposed blunt and pointed ends of said vessel;   propulsion means mounted to said vessel for propelling said vessel in a first forward direction of operation defined by said pointed end being forward as said vessel operates as a planing boat and for propelling said vessel in a second forward direction of operation defined by said blunt end being forward when said vessel operates as a submarine;   a rudder located near said pointed end of said vessel for steering said vessel when said vessel moves with said blunt end forward;   a plurality of vanes for steering said vessel as said vessel submerges and ascends; and   at least one ballast tank. .Iaddend..Iadd.8. A vessel which can operate both as a planing boat and as a submarine, comprising:   a blunt end and an opposed second end of said vessel;   propulsion means mounted to said vessel for propelling said vessel in a first forward direction of operation defined by said second end being forward when said vessel operates as a planing boat and for propelling said vessel in a second forward direction of operation defined by said blunt end being forward when said vessel operates as a submarine;   means mounted to said vessel for steering said vessel when said vessel moves with said blunt end forward or said second end forward;   
     
     
       means mounted to said vessel for ballasting said vessel. .Iaddend..Iadd.9. The vessel of claim 6 wherein said steering means comprises: means for steering said vessel from port to starboard; and   means for steering said vessel in pitch. .Iaddend..Iadd.10. The vessel of claim 6 wherein said means for steering from port to starboard is a rudder. .Iaddend..Iadd.11. The vessel of claim 6 wherein said steering means further comprises means for steering said vessel during ascent and descent. .Iaddend..Iadd.12. The vessel of claim 11 wherein said means for steering said vessel during ascent and descent is a plurality of planes. .Iaddend..Iadd.13. The vessel of claim 6 wherein said means for adjustably ballasting said vessel is at least one ballast tank. .Iaddend.
