SUMMARY
The discussion focuses on calculating the ship's heading and ground velocity when sailing east against a current of 5.0 km/h [N] with an engine speed of 20 km/h. To maintain a position relative to the ground, the ship must adjust its heading to account for the current. Using vector analysis, specifically x/y components, allows for the determination of the required velocity of the ship with respect to the water.
