In this note, we briefly discuss and compare the simplified models of the water current and wind effects on ship’s resultant track in marine navigation, which are represented by drift and leeway. Our focus is on a compensation of the lateral component of perturbation with respect to the ship heading line, which is included in the equations of resultant motion. The variable magnitude of the compensation affects ship navigation, in particular, total drift angle, speed and course over ground. The corresponding unit time fronts, speed changes and drift angle in relation to the various ranges of the cross compensation and own ship true course are also compared by some illustrative examples.
