An aquatic gliding board such as a surfboard is constructed using a honeycomb material for the core. The composite outer skin of the surfboard is constructed of materials having similar flexibility properties as found in a traditional foam/fiberglass surfboard. In a particularly preferred embodiment an aluminum honeycomb core is employed along with a fiberglass skin in order to achieve a surfboard with decreased weight and increased strength to resist failure in bending relative to a traditional foam/fiberglass surfboard, but having similar flexibility characteristics to such a traditional surfboard, or having increased flexibility relative to such a traditional surfboard.

1. An aquatic gliding board, comprising: a skin extending longitudinally from a tip to a tail and defining a deck, a bottom, and first and second rails, the deck and bottom spaced from one another, the first and second rails each extending between and connecting the deck and bottom so that an enclosed core space is defined by the deck, bottom, first rail and second rail;a honeycomb core enclosed within the core space and generally shaped to complement the core space, the honeycomb core being elongate from a tip to a tail, having deck and bottom sides and having first and second edges, the honeycomb core comprising a plurality of generally hollow cells arranged so that a longitudinal center line of at least one of the cells is transverse to the core deck and bottom sides, at least some cells of the honeycomb core extending between, engaging, and being tightly adhered to the skin deck and skin bottom, a first rail space being defined between the first edge of the core and the skin first rail, a second rail space being defined between the second edge of the core and the skin second rail; andfirst and second inserts disposed in the first and second rail spaces, respectively, the first and second inserts configured to provide support in a direction generally transverse to the longitudinal center line of the at least one of the honeycomb cells. 2. An aquatic gliding board as in claim 1, wherein the insert comprises a honeycomb material having cells, and a longitudinal center line of at least one of the honeycomb cells of the insert is generally transverse to the longitudinal center line of the at least one of the honeycomb core cells. 3. An aquatic gliding board as in claim 1, wherein the insert comprises an expanded foam. 4. An aquatic gliding board as in claim 1, wherein the skin comprises fibers suspended in a cured matrix. 5. An aquatic gliding board as in claim 4, wherein the skin comprises a deck skin having a body portion and a rail portion and a bottom skin having a body portion and a rail portion, each rail portion being arranged about edges of the respective deck skin or bottom skin and each rail portion being curved so as to extend transverse to the respective body portion, deck skin rail portion and bottom skin rail portions overlap one another, and wherein the deck skin defines the deck, the bottom skin defines the bottom, and the first and second rails comprise the overlapping rail portions. 6. An aquatic gliding board as in claim 5, wherein the skin is generally thickest at the overlapping rail portions. 7. An aquatic gliding board as in claim 5, wherein at least one of the overlapping rail portions of the deck skin and bottom skin is in tension. 8. An aquatic gliding board as in claim 5 additionally comprising a rail layer comprising fibers suspended in a cured matrix, the rail layer being adhered to the rail. 9. An aquatic gliding board as in claim 8, wherein the fibers in the deck and bottom skin portions are glass fibers, and wherein the rail layer comprises fibers other than glass fibers. 10. An aquatic gliding board as in claim 9, wherein in the rail layer comprises aramid fibers. 11. An aquatic gliding board as in claim 4, wherein at least a portion of the skin comprises a viscoelastic layer. 12. An aquatic gliding board as in claim 4 additionally comprising a support material adhered to a portion of the deck where a rider is likely to place his feet during riding. 13. An aquatic gliding board as in claim 4, wherein a layer of a non-fibrous material is attached to a portion of one or more of the skin deck and bottom. 14. An aquatic gliding board as in claim 1, wherein: the honeycomb core cells have a cell size of ⅛ inch to 3/8 inch; andthe skin has a Young's modulus (Ef), an outer surface of the skin having a curving shape adapted so that a thickness of the surfboard varies along a longitudinal length and a transverse width of the surfboard;wherein the honeycomb core has a compressive modulus (Ec), and a longitudinal center line of at least one cell of the honeycomb core is directed generally perpendicular to the deck skin portion ; andwherein a ratio of the Young's modulus of the skin to the compressive modulus of the core (Ef/Ec) is 250 or less, and the core has a density of 3.5 lb./ft^3 or less. 15. An aquatic gliding board as in claim 14, wherein the honeycomb core comprises aluminum. 16. An aquatic gliding board as in claim 14, wherein the core has a density of 2.9 lb./ft^3 or less. 17. An aquatic gliding board as in claim 16, wherein the ratio of the Young's modulus of the skin to the compressive modulus of the core is 50 or less. 18. An aquatic gliding board as in claim 15, wherein the ratio of the Young's modulus of the skin to the compressive modulus of the core is 75 or less. 19. An aquatic gliding board as in claim 5, wherein the deck skin and the bottom skin are separately formed, and the overlapping rail portions are adhered together via an adhesive. 20. An aquatic gliding board as in claim 14, wherein the honeycomb core comprises Nomex.
