What is claimed is: 1. A double-layer boat hull structure defining a bow section, a draft section, a stern section and an amidships section, wherein said hull structure comprises an inner layer formed of a plurality of inner plates, an outer layer formed of a plurality of outer plates, a plurality of spacer plates connected between said inner plates and said outer plates to keep said inner layer and said outer layer spaced at a distance and to define a plurality of independent air chambers between said inner layer and said outer layer, and fastening members affixing said spacer plates to said outer plates and said inner plates, said outer plates each having two mounting flanges respectively perpendicularly extending from two opposite lateral sides thereof and a plurality of mounting through holes cut through the mounting flanges and arranged in line along each of the two opposite lateral sides, said inner plates each having two mounting flanges respectively perpendicularly extending from two opposite lateral sides thereof and a plurality of mounting through holes cut through the mounting flanges and arranged in line along each of the two opposite lateral sides, said spacer plates each having a first lateral side sandwiched between the mounting flanges of two adjacent outer plates, a second lateral side sandwiched between the mounting flanges of two adjacent inner plates, and a plurality of mounting through holes arranged in two lines along the first lateral side and the second lateral side and respectively connected between the mounting through holes on the mounting flanges of the associated outer plates and the mounting through holes on the mounting flanges of the associated inner plates by said fastening members. 2. The double-layer boat hull structure as claimed in claim 1, wherein said fastening members each comprise a screw, and a female screw threaded onto said screw. 3. The double-layer boat hull structure as claimed in claim 1, wherein said inner layer defines a bilge and has reinforcing plates transversely affixed to the bilge. 4. The double-layer boat hull structure as claimed in claim 1, wherein the mounting flanges of said outer plates and the mounting flanges of said inner plates respectively extend toward the outside of the hull structure. 5. The double-layer boat hull structure as claimed in claim 1, wherein the mounting flanges of said outer plates and the mounting flanges of said inner plates respectively extend toward the inside of the hull structure. 6. The double-layer boat hull structure as claimed in claim 1, wherein said outer plates, said inner plates and said spacer plates are metal plates. 7. The double-layer boat hull structure as claimed in claim 1, wherein said outer plates, said inner plates and said spacer plates are plastic plates. 8. The double-layer boat hull structure as claimed in claim 1, wherein said outer plates, said inner plates and said spacer plates are made out of a composite material. 9. The double-layer boat hull structure as claimed in claim 1, wherein the draft section of the hull structure has a flat bottom. 10. The double-layer boat as claimed in claim 1, wherein the draft section of the hull structure has a double-bevel bottom. 11. The double-layer boat hull structure as claimed in claim 1, wherein said independent air chambers are respectively stuffed with a foam material. 12. The double-layer boat hull structure as claimed in claim 1, which is a raft.
