An apparatus for varying the dimensions of a hull of a vessel comprising an arcuate truss assembly having a plurality of members pivotally joined. The arcuate truss assembly is operatively arranged to form a portion of the hull. The assembly is operatively arranged to extend and retract to vary the dimensions of the hull when the plurality of members are pivoted with respect to one another. The members of the arcuate truss assembly pivot in a plane substantially coplanar with the portion of the vessel hull.

What is claimed is: 1. An apparatus for varying the dimensions of a marine vessel having a buoyant hull comprising: an arcuate truss assembly having a plurality of members pivotally joined, said assembly operatively arranged to form a portion of said buoyant hull in contact with water, said truss a
What is claimed is: 1. An apparatus for varying the dimensions of a marine vessel having a buoyant hull comprising: an arcuate truss assembly having a plurality of members pivotally joined, said assembly operatively arranged to form a portion of said buoyant hull in contact with water, said truss assembly operatively arranged to extend and retract to vary the dimensions of said hull when said plurality of members are pivoted with respect to one another, said members pivoting in a plane substantially coplanar with said portion of said buoyant hull, and said hull remains buoyant when said assembly is fully retracted; and, pneumatic means operatively arranged to extend and retract said assembly. 2. The apparatus recited in claim 1 further comprising a flexible membrane, said membrane connected to said hull around the periphery of said membrane, said membrane operatively arranged to cover said assembly, said membrane operatively arranged to extend and retract as said assembly extends and retracts. 3. The apparatus recited in claim 2 wherein said membrane comprises urethane. 4. The apparatus recited in claim 2 wherein said membrane is connected to said hull with a watertight seal. 5. The apparatus recited in claim 2 wherein said membrane is operatively arranged to retract in a diaphragm shutter like fashion when said assembly is retracted. 6. The apparatus recited in claim 1 further comprising a plurality of plates, said plates operatively arranged to cover said assembly when said assembly is substantially fully extended. 7. The apparatus recited in claim 6 wherein said plates form a watertight seal with said hull when said assembly is substantially fully extended. 8. The apparatus recited in claim 1 wherein said assembly is operatively arranged to extend and retract in a diaphragm shutter like fashion. 9. The apparatus recited in claim 1 wherein said vessel is a waterborne vessel. 10. The apparatus recited in claim 1 wherein said vessel is a submersible vessel. 11. An apparatus for varying the dimensions of a marine vessel having a buoyant hull comprising: an arcuate truss assembly having a plurality of members pivotally joined, said assembly operatively arranged to form a portion of said buoyant hull in contact with water, said truss assembly operatively arranged to extend and retract to vary the dimensions of said hull when said plurality of members are pivoted with respect to one another, said members pivoting in a plane substantially coplanar with said portion of said buoyant hull, and said hull remains is buoyant when said assembly is fully retracted; and, hydraulic means operatively arranged to extend and retract said assembly. 12. An apparatus for varying the dimensions of a marine vessel having a buoyant hull comprising: an arcuate truss assembly having a plurality of members pivotally joined, said assembly operatively arranged to form a portion of said buoyant hull in contact with water, said truss assembly operatively arranged to extend and retract to vary the dimensions of said hull when said plurality of members are pivoted with respect to one another, said members pivoting in a plane substantially coplanar with said portion of said buoyant hull, and said hull remains buoyant when said assembly is fully retracted; and, microelectromechanical systems (MEMS) means operatively arranged to extend and retract said assembly. 13. A marine vessel comprising: a buoyant hull; an arcuate truss assembly having a plurality of members pivotally joined, said truss assembly operatively arranged to form a portion of said buoyant hull in contact with water, said truss assembly operatively arranged to extend and retract to vary the dimensions of said hull when said plurality of members are pivoted with respect to one another, said members pivoting in a plane substantially coplanar with said portion of said buoyant hull, and said hull remains buoyant when said assembly is fully retracted; and, pneumatic means operatively arranged to extend and retract said assembly. 14. The vessel recited in claim 13 further comprising a flexible membrane, said membrane connected to said hull around the periphery of said membrane, said membrane operatively arranged to cover said assembly, said membrane operatively arranged to extend and retract as said assembly extends and retracts. 15. The vessel recited in claim 14 wherein said membrane comprises urethane. 16. The vessel recited in claim 14 wherein said membrane is connected to said hull with a watertight seal. 17. The apparatus recited in claim 14 wherein said membrane is operatively arranged to retract in a diaphragm shutter like fashion when said assembly is retracted. 18. The vessel recited in claim 13 further comprising a plurality of plates, said plates operatively arranged to cover said assembly when said assembly is substantially fully extended. 19. The vessel recited in claim 18 wherein said plates form a watertight seal with said hull when said assembly is substantially fully extended. 20. The apparatus recited in claim 13 wherein said assembly is operatively arranged to extend and retract in a diaphragm shutter like fashion. 21. The apparatus recited in claim 13 wherein said vessel is a waterborne vessel. 22. The apparatus recited in claim 13 wherein said vessel is a submersible vessel. 23. A marine vessel comprising: a buoyant hull; an arcuate truss assembly having a plurality of members pivotally joined, said truss assembly operatively arranged to form a portion of said buoyant hull in contact with water, said truss assembly operatively arranged to extend and retract to vary the dimensions of said hull when said plurality of members are pivoted with respect to one another, said members pivoting in a plane substantially coplanar with said portion of said buoyant hull, and said hull remains buoyant when said assembly is fully retracted; and, hydraulic means operatively arranged to extend and retract said assembly. 24. A marine vessel comprising: a buoyant hull; an arcuate truss assembly having a plurality of members pivotally joined, said truss assembly operatively arranged to form a portion of said buoyant hull in contact with water, said truss assembly operatively arranged to extend and retract to vary the dimensions of said hull when said plurality of members are pivoted with respect to one another, said members pivoting in a plane substantially coplanar with said portion of said buoyant hull, and said hull remains buoyant when said assembly is fully retracted; and, microelectromechanical systems (MEMS) means operatively arranged to extend and retract said assembly.
