Nautical Term: Parallel midbody

Definition of Parallel midbody

Parallel midbody refers to the central portion of a ship’s hull where the longitudinal contour remains unchanged.

For instance, when comparing the hydrodynamic performances of two different ship designs, marine engineers would often focus on the parallel midbody of each vessel to ensure a fair comparison. This is because any differences in hydrodynamic performance between the two designs, which could be attributed to variations in the parallel midbody, would need to be carefully accounted for in any analysis or reporting of the results.
