Hull structure made of composite material that includes a hull with high thickness “single skin” monocoque plating without reinforcements and an internal stiffening structure (1) formed by a deck (2), two opposing transverse bulkheads (3) and more cradle-shaped load-bearing elements (5) to support components or machinery intended to be housed on board said hull structure. Advantageously, the above-mentioned cradle-shaped load-bearing elements (5) are supported at the respective internal portions of said opposite transverse bulkheads (3) only at their opposite head ends (5b).
