A surfboard having composite covered honeycomb deck and bottom surfaces. The surfboard has a hollow inner volume which contains a longitudinally oriented stringer. The stringer is spaced both from the nose of the surfboard and from the tail of the surfboard so that the nose and tail are more flexible than the length containing the stringer. The process of making the board is also disclosed.

1. A surfboard having a deck and a bottom, a nose and a tail, and a surfboard length, said surfboard comprising:a deck fabricated from a laminate having outer and inner composite layers surrounding a deck intermediate core fabricated from a honeycomb material, said deck having a peripheral edge;a bottom fabricated from a laminate having an outer and inner composite layers surrounding a bottom intermediate core fabricated from a honeycomb material, and said bottom having a bottom peripheral edge, said deck peripheral edge being sealed to said bottom peripheral edge to form a closed hollow structure; anda stringer comprising an elongated member having an upper stringer surface and a lower stringer surface, a forward end and a rear end, and a stringer length, said stringer being contained within said closed hollow structure and the upper stringer surface being adhered to said deck by an upper adhesive composition and said lower stringer surface being adhered to said bottom by a lower adhesive composition and at least one of said upper adhesive composition and said lower adhesive composition including a layer of foam. 2. The surfboard of claim 1 wherein said layer of foam is located in said lower adhesive composition. 3. The surfboard of claim 1 wherein forward end of said stringer is spaced from said nose and the rear end of said stringer is spaced from said tail. 4. The surfboard of claim 3 wherein said stringer length is about one half of said surfboard length. 5. The surfboard of claim 4 wherein said stringer is positioned closer to the rear of said surfboard than to the nose thereof. 6. The surfboard of claim 5 wherein the distance between the forward end of said stringer and the nose of the surfboard is about twice the distance between the rear end of said stringer and the tail of the surfboard. 7. The surfboard of claim 1 wherein said stringer has a C-shaped cross sectional shape. 8. The surfboard of claim 1 wherein said layer of foam is about one quarter of an inch thick. 9. The surfboard of claim 1 wherein said layer of foam is a polyurethane foam. 10. The surfboard of claim 1 wherein said stringer is fabricated from a composite of resin and fibers. 11. The surfboard of claim 1 wherein at least one of said upper and lower adhesive compositions includes a vibration dampening layer. 12. A surfboard comprising:a deck fabricated from an upper honeycomb core sandwiched between upper and lower composite layers and said upper deck having a deck peripheral edge;a bottom fabricated from a lower honeycomb core sandwiched between upper and lower composite layers and said bottom having a bottom peripheral edge joined to said deck peripheral edge to form a surfboard shell having a hollow interior volume and having a nose and a tail and a surfboard length between the nose and tail; andan elongated stringer located within said hollow interior volume, said stringer having an upper surface, a lower surface, a forward end, a rear end, and a length and said stringer being adhered to said deck and bottom along its upper and lower surfaces respectively, and said forward end of said stringer being spaced from the nose of the surfboard and the rear end of said stringer being spaced from the tail of said surfboard. 13. The surfboard of claim 12 wherein the length of the stringer is about one half that of the surfboard length. 14. The surfboard of claim 12 wherein said stringer has a C-shaped cross sectional shape and is fabricated from a composite material. 15. The surfboard of claim 12 wherein said stringer is a first stringer and further including a second stringer located within said hollow interior volume, said second stringer having an upper surface, a lower surface, a forward end, a rear end, and a length and said second stringer being adhered to said deck and bottom along its upper and lower surfaces respectively, and said forward end of said second stringer being spaced from the nose of the surfboard and the rear end of said second stri nger being spaced from the tail of said surfboard and said surfboard having a longitudinal axis and said first and second stringers being parallel to one another and equally spaced from said longitudinal axis. 16. The surfboard of claim 12 wherein said honeycomb cores are fabricated from aluminum. 17. A process for forming a hollow surfboard comprising:forming a first layer of honeycomb core into the shape of a deck of a surfboard;covering a top and a bottom of said first layer of honeycomb core with an upper and a lower uncured resin and fiber composite sheet, said upper and lower fiberglass sheets extending past an outer peripheral edge of said first layer of honeycomb core to form a deck laminate with an outer peripheral deck flap;placing said deck laminate on a shaped, concave deck mold and surrounding said concave deck mold with a vacuum bag;drawing a vacuum on said vacuum bag and heating the deck mold to cause said deck laminate to cure to form a cured deck piece;forming a second layer of honeycomb core into the shape of a bottom of a surfboard;covering a top and a bottom of said second layer of honeycomb core with an upper and a lower uncured resin and fiber composite sheet, said upper and lower fiberglass sheets extending past an outer peripheral edge of said second layer of honeycomb core to form a bottom laminate with an outer peripheral bottom flap;placing said bottom laminate on a shaped, concave bottom mold and surrounding said concave bottom mold with a vacuum bag;drawing a vacuum on said vacuum bag and heating the bottom mold to cause said bottom laminate to cure to form a cured bottom piece;removing said vacuum bags;adhering a stringer to an inner surface of one of said cured deck piece and said cured bottom piece parallel to a longitudinal axis of said one of said cured deck piece and said cured bottom piece;placing an adhesive composition in a contact area where said stringer will be adhered to the other of said cured deck piece and said cured bottom piece; andjoining said cured deck piece to said cured bottom piece and said stringer to said other of said cured deck piece and said cured bottom piece said joining step being accomplished by adhering said outer peripheral deck flap to said outer peripheral bottom flap to form a hollow surfboard enclosing an elongated stringer secured within said hollow surfboard. 18. The process of claim 17 wherein said adhering step adheres said stringer to said inner surface of said deck piece. 19. The process of claim 17 wherein said placing an adhesive composition step includes depositing a layer of polyurethane prefoam at said contact area immediately before said joining step.
