4. The side section for the gangplank structure as specified in claim 1 wherein the sigma spring section extends a distance which is within ±25% of the length of the horizontal base section.

5. The side section for the gangplank structure as specified in claim 1 wherein the side section is further comprised of a handrail which extends upwardly from at least two points along longitudinal axis of the vertical deck support.

6. The side section for the gangplank structure as specified in claim 1 wherein the fulcrum is situated on the lower deck support at a point which is situated about 25% to 45% of the distance from the outside end of lower deck support to the inside end of lower deck support.

7. The side section for the gangplank structure as specified in claim 5 wherein the handrail extends from a point at one longitudinal end of the vertical deck support to a point at the opposite longitudinal end of the vertical deck support.

8. The side section for the gangplank structure as specified in claim 7 the handrail extends from the vertical deck support at a plurality of points along the longitudinal axis of the vertical deck support.

9. A deck structure which is comprised of a first side section, a second side section, and one or more deck sections, wherein the first side section and the second side section are as specified in claim 1 and wherein the deck sections extend from the first side section to the second side section to form the deck structure.

10. The deck structure as specified in claim 9 wherein the deck section extends into the deck engaging cavity of the first side section and wherein the deck section extends into the deck engaging cavity of the second side section.

11. The deck structure as specified in claim 9 wherein the deck sections are comprised of a multitude of planks.

12. The deck structure as specified in claim 9 wherein the deck structure is a gangplank, and wherein the horizontal base section is affixed to a hinge at one end of the deck structure and a roller at the opposite end of the deck structure.

13. The deck structure as specified in claim 9 wherein the deck structure is a floating dock, and wherein the horizontal base section is affixed to one or more float drums on the bottom side of the horizontal base section.

14. The deck structure as specified in claim 9 wherein the deck structure is a stationary dock, and wherein the horizontal base section is affixed to one or more anchoring poles.

15. The deck structure as specified in claim 9 wherein the deck structure is a swim platform, and wherein the horizontal base section is affixed to one or more float drums on the bottom side of the horizontal base section.

16. The deck structure as specified in claim 9 wherein the deck structure is a swim platform, and wherein the horizontal base section is affixed to one or more anchoring poles.

17. A gangway structure which is comprised of a first side section, a second side section, a first end section, a second end section, and one or more deck sections, wherein the first side section and the second side section are as specified in claim 1 , wherein the deck sections extend from the first side section to the second side section to form the deck structure, wherein the first end section extends from the first side section to the second side section on a first end of the gangway structure, and wherein the second end section extends from the first side section to the second side section on a second end of the gangway structure.

18. The gangway structure as specified in claim 17 wherein at least one hinge is affixed to the first end of the gangway structure.

19. The gangway structure as specified in claim 18 wherein at least one roller is affixed to the second end of the gangway structure.
