A tie down assembly including a cup, a cross-shaped crossbar that is fastened removably to and positioned within a recess of the cup, and a disc-shaped plate that is fastened removably to the cup and/or the crossbar. The crossbar is fastened to the cup by a plurality of fasteners, while the plate is fastened to the cup and/or the crossbar by at least one fastener. The cup is installed within a hole formed within a first surface of a structure, and the plate is positioned against an opposite surface of the structure. When the plate is attached, a compressive load is introduced and squeezes the first and second surfaces of the structure together, such that most of the load is borne down the center of the fastener attaching the plate.

1. A tie down assembly adapted to be installed in a structure, comprising: a cup having a first end, a second end opposite the first end, a recess formed within the first end and defining a sidewall having a plurality of apertures formed therein, a centrally-located aperture formed within the recess at the second end, and a stem extending from the second end and including an aperture that extends the length of the stem, the aperture of the stem being aligned with the centrally-located aperture of the recess;a crossbar having a plurality of members each of which includes a first end having an aperture formed axially therein, each of the plurality of members being joined to one another at a central point, and a stem extending perpendicularly from the central point of the plurality of members, the stem of the crossbar including a first end with an aperture formed axially therein, the crossbar being positioned within the recess of the cup such that each of the apertures of the plurality of members of the crossbar aligns with a corresponding one of the plurality of apertures of the sidewall of the cup, each of the aligned apertures of the sidewall of the cup and the apertures of the plurality of members are sized and shaped to receive one of a first plurality of fasteners, and the stem of the crossbar aligns with the stem of the cup such that the aperture of the stem of the crossbar aligns with the aperture of the stem of the cup, the aligned aperture of the stem of the crossbar and the aperture of the stem of the cup are sized and shaped to receive a second fastener;and a support plate having a first surface, a second surface opposite the first surface, and an aperture extending from the first surface to the second surface, the support plate being attached removably to the crossbar such that the aperture of the plate is sized and shaped to receive the second fastener. 2. The tie down assembly of claim 1, wherein the structure includes a first surface and a second surface opposite the first surface of the structure, the first surface of the structure including a first hole formed therein that is sized and shaped to receive the cup, and wherein the first surface of the support plate is juxtaposed with the second surface of the structure. 3. The tie down assembly of claim 2, wherein the second surface of the structure includes a second hole formed therein that is sized and shaped to receive the second fastener. 4. The tie down assembly of claim 3, wherein the cup includes a flange surrounding a perimeter of the recess and having a top surface and a bottom surface opposite the top surface, the flange of the cup rests on the first surface of the structure. 5. The tie down assembly of claim 4, wherein the bottom surface of the flange of the cup includes a groove formed therein that is sized and shaped to receive an O-ring. 6. The tie down assembly of claim 5, wherein the sidewall of the cup includes a plurality of tabs extending outwardly therefrom and positioned proximate to the bottom surface of the flange of the cup, and wherein the first surface of the structure includes a plurality of notches formed therein, each of the plurality of notches is sized and shaped to receive a corresponding one of the plurality of tabs of the cup so as to inhibit rotation of the tie down assembly relative to the first surface of the structure. 7. The tie down assembly of claim 1, wherein each of the apertures of the plurality of members includes internal threads for threadedly receiving a corresponding one of the first plurality of fasteners, and wherein the aperture of the stem of the crossbar includes internal threads for threadedly receiving the second fastener. 8. The tie down assembly of claim 1, wherein the cup and the support plate are each made from aluminum, and the crossbar is made from steel. 9. The tie down assembly of claim 1, wherein the plurality of members includes four of the members. 10. The tie down assembly of claim 9, wherein each of the plurality of members of the crossbar extends substantially in the same plane. 11. The tie down assembly of claim 10, further comprising a gasket positioned between the first end of the stem of the crossbar and the recess of the cup. 12. The tie down assembly of claim 11, wherein each of the first ends of the plurality of members includes a groove that is sized and shaped to receive an O-ring. 13. The tie down assembly of claim 1, wherein the first and second surfaces of the support plate are separated by a plurality of ribs. 14. The tie down assembly of claim 1, wherein the structure is made from aluminum. 15. The tie down assembly of claim 14, wherein the structure includes a deck of a vessel.
