A lightweight, ergonomically beneficial, hydrodynamic, and volumetrically efficient hybrid pressure vessel having at least two longitudinally extending, semi-cylindrical sections with flattened rib portions at a common interface between the sections. Additional longitudinally extending sections may be employed to provide additional internal volume. One or more apertures extend through the ribs to provide communication between sections. The pressure vessel comprises a cast metal material, optionally including exterior reinforcing structure for containing internal pressure.

What is claimed is: 1. A pressure vessel comprising:at least two longitudinally extending sections, each including a side wall, a first substantially hemispherical end wall, and a second substantially hemispherical end wall;a first rib formed between the at least two sections and including at least one aperture extending therethrough; andthe first rib and each side wall, first end wall, and second end wall of the at least two sections collectively forming a seamless, unitary structure of a metal material.
