Claims: What is claimed is:

1. Building equipment for a ship's hull located on land adjacent a body of water, comprising: a hull joining stage having a substantially horizontal bottom surface level substantially flush with the ground level of the site and having a first longitudinal side facing the body of water and a second longitudinal side facing the land; a stern building stage having a substantially horizontal bottom surface level substantially flush with the bottom surface of said hull joining stage, provided at a longitudinal end of said hull joining stage so as to be adjacent thereto through a gate; a bow and parallel body building stage having a substantially horizontal bottom surface level substantially flush with the bottom surface of said hull joining stage, provided at the other longitudinal end of said hull joining stage so as to be adjacent thereto through another gate; a pond provided longitudinally and substantially in parallel with and adjacent to said hull joining stage on the water side, a longitudinal end of said pond being open to the body of water through still another gate, and the bottom surface of said pond being sufficiently lower than the bottom surface of said hull joining stage to enable a hull in said pond to float completely when the water level in said pond becomes flush with the level of the body of water by introducing water from the body of water into said pond; cranes travelling substantially linearly along said hull joining stage, said stern building stage, and said bow and parallel body building stage; and partition walls comprehensively enclosing said hull joining stage and said pond in a water-tight manner in conjunction with said three gates, said partition walls and said three gates being sufficiently higher than the ground level and the level of the body of water to enable a hull in said hull joining stage to float completely on introducing water from the body of water into both said hull joining stage and said pond.

2. The building equipment for a hull of claim 1, wherein said bow and parallel body building stage is divided into a bow building stage and a parallel body building stage; said bow building stage having a substantially horizontal bottom surface level substantially flush with the bottom surface of said hull joining stage, being provided at the other longitudinal end of the hull joining stage so as to be adjacent thereto through the gate; and said parallel body building stage having a substantially horizontal bottom surface level substantially flush with the bottom surface of said hull joining stage, being provided substantially longitudinally in parallel with and adjacent to said hull joining stage on the land side through a gate arranged in the longitudinal side wall of the partition walls on the land side.
