Pb(1+x)

: the flow does not wrap around the trailing edge, meaning there is no local jump in the velocity

The ease of a boat to maintain its direction after being deflected

Speed at which the Froude number for ship and model are equal

Ctm-(Cfm-Cfs)

Friction + pressure

Powering estimates, hull form, judging hull quality

When speeds of ship and model are in ratio of square root of their lengths, then resistance due to wave making varies with their displacements

wave + viscous
