Underwater personal submersible

1. An underwater personal submersible comprising:

a main section having a forward end and a rearward end, the main section including a user compartment and an observation chamber, at least one oxygen tank connected to the user compartment, at least one buoyancy compartment, and a propulsion mechanism comprising at least one thruster mechanism;

first and second forward side supports of the main section;

wherein the user compartment is configured to receive and support an operator in a face down orientation, the user compartment defining a first forwardly and outwardly arm receiving portion containing a controller for operating the underwater personal submersible and a second forwardly and outwardly arm receiving portion;

wherein the user compartment defines a support inclined upwards toward the forward end of the main section at least 20 degrees from horizontal when the underwater personal submersible is positioned on a horizontal surface and the first and second forwardly and outwardly arm receiving portions are configured to receive the operator's arms in an outstretched position with the controller within the first forwardly and outwardly arm receiving portion and below the operator's chest relative to the horizontal when the underwater personal submersible is positioned on the horizontal surface; and

wherein the first forwardly and outwardly extending arm receiving portion extends onto one of the first and second forward side supports of the main section.

2. The underwater personal submersible of claim 1 further comprising at least one membrane at least partially defining an inflatable chamber within the user compartment.

3. The underwater personal submersible of claim 2 , wherein said membrane provides cushioning for comfort and support of a user.

4. The underwater personal submersible of claim 3 , wherein said membrane at least partially encloses a source of ballast.

5. The underwater personal submersible of claim 4 , wherein the source of ballast is water permitted to enter the inflatable chamber.

6. The underwater personal submersible of claim 5 further comprising a valve to control the entry of ballast into the inflatable chamber.

7. The underwater personal submersible of claim 6 , wherein the inflatable chamber occupies at least 20% of an inner volume of the user compartment.

8. The underwater personal submersible of claim 6 , wherein the inflatable chamber occupies at least 30% of an inner volume of the user compartment.

9. The underwater personal submersible of claim 1 , wherein the total weight of the underwater personal submersible is less than 4000 lbs.

10. The underwater personal submersible of claim 1 , wherein the total weight of the underwater personal submersible is less than 3000 lbs.

11. The underwater personal submersible of claim 1 further comprising a plurality of attachment members configured such that the submersible can lift and transport an object while underwater and while remaining vertically stable.

12. The underwater personal submersible of claim 1 further comprising a manipulable member connected to the underside of the submersible and configured such that the submersible can lift and transport an object while underwater and while remaining vertically stable.

13. The underwater personal submersible of claim 1 further comprising:

a secondary ballast system comprising at least one inflatable membrane located within the user compartment enclosing a source of ballast and which is inflatable to conform to the user's body within the user compartment to provide comfort for the user during operation of the submersible.

14. The underwater personal submersible of claim 1 , wherein the self-propulsion mechanism comprises a plurality of thruster mechanisms, each thruster mechanism comprising an inlet, a nozzle outlet, a propeller, and a steering mechanism, wherein the propeller directs water out of the nozzle outlet to propel the submersible in a determined direction and the steering mechanism is rotatable such that the submersible may be steered in the determined direction.
