An airship (100) for conveyance through a fluid medium in a selected direction of travel. The airship includes a hull adapted to contain a lifting medium therein, wherein the hull (108) includes a first section having a width which varies along the selected direction of travel, the width increasing from a bow of the hull to a maximum width and decreasing from the maximum width to a tail section of the first section; and a second section coupled to the first section and having a width which varies along the selected direction of travel, the width increasing from a leading edge of the second section to a maximum width and decreasing from the maximum width to a stern of the hull.

1. An airship comprising a hull adapted to contain a lifting medium therein, wherein the hull has a width that varies along a length of the hull, and a height, wherein a maximum width of the hull is equal to the height of the hull divided by a number between about 3.3 and about 6.7, wherein the hull
1. An airship comprising a hull adapted to contain a lifting medium therein, wherein the hull has a width that varies along a length of the hull, and a height, wherein a maximum width of the hull is equal to the height of the hull divided by a number between about 3.3 and about 6.7, wherein the hull further comprises a first section coupled to and located forward of a second section, wherein the first section comprises an arcuate shaped front section and an arcuate shaped tail section, and wherein the second section comprises an arcuate shaped front section and a tapered tail section.2. The airship of claim 1, wherein the width remains substantially constant along the height of the hull.3. The airship of claim 1, wherein the width of the hull increases to the maximum width at the first section, decreases and then increases to the maximum width at the second section, and decreases towards a stern of the hull.4. The airship of claim 3, wherein the hull further comprises a plurality of bladders, wherein the first section contains at least two bladders, and the second section contains at least three bladders.5. The airship of claim 1, wherein the hull further comprises a plurality of bladders adapted to contain the lifting medium.6. The airship of claim 5, wherein each of the bladders are elongate in shape and have a height, a width, and a central axis parallel with the height of each bladder.7. The airship of claim 5, wherein each of the bladders are cylindrical in shape.8. The airship of claim 1, further comprising a propulsion source coupled to the hull and adapted to generate a thrust about a thrust axis, wherein the propulsion source is gimbaled such that the thrust axis may pivot.9. The airship of claim 1, further comprising a spinner thruster coupled to the hull and adapted to generate a thrust about a thrust axis, wherein the spinner thruster is gimbaled such that the thrust axis may pivot, and wherein the spinner thruster is spaced from a center of mass of the airship.10. An airship comprising a hull adapted to contain a lifting medium therein, wherein the hull has a leading edge, a trailing edge, and a width that varies along an axis extending between the leading and trailing edges and is substantially constant along a height of the hull, wherein the hull further comprises a first section coupled to and located forward of a second section, wherein the first section comprises an arcuate shaped front section and an arcuate shaped tail section, and wherein the second section comprises an arcuate shaped front section and a tapered tail section.11. The airship of claim 10, wherein a maximum width of the hull is equal to the height of the hull divided by a number between about 3.3 and about 6.7.12. The airship of claim 10, wherein the width of the hull increases to the maximum width at the first section, decreases and then increases to the maximum width at the second section, and decreases towards a stern of the hull.13. The airship of claim 12, wherein the hull further comprises a plurality of bladders, wherein the first section contains at least two bladders, and the second section contains at least three bladders.14. The airship of claim 10, wherein the hull further comprises a plurality of bladders adapted to contain the lifting medium.15. The airship of claim 14, wherein each of the bladders are elongate in shape and have a height, a width, and a central axis intersecting the center of the bladder, wherein each of the central axes are oriented parallel with the length of each bladder and are inclined relative to the selected direction of travel.16. The airship of claim 14, wherein each of the bladders are cylindrical in shape.17. The airship of claim 10, further comprising a propulsion source coupled to the hull and adapted to generate a thrust about a thrust axis, wherein the propulsion source is gimbaled such that the thrust axis may pivot.18. The airship of claim 10, further comprising a spinner thruster coupled to the hull and adapted to generate a thrust about a thrust axis, wherein the spinner thruster is gimbaled such that the thrust axis may pivot, and wherein the spinner thruster is spaced from a center of mass of the airship.
