Hydrodynamic forces do not scale in a uniform linear manner, requiring marine engineers to prioritize specific fluid properties based on a vessel's operational profile. At small model dimensions, scaling errors like surface tension and water viscosity can inject unwanted air pockets or create artificial drag.

For high-speed patrol craft, designers prioritize Reynolds number similarity to analyze skin friction drag accurately along the plates. Conversely, for large displacement bulk carriers where wave generation dominates, engineers accept minor viscosity errors to focus their testing budget on exact wavefield reproduction.
