When a tug is pulling on a hawser at right angles to the ship, and the pilot wants to come ahead or astern on the ship's engine, care must be taken that the pilot __________.

Correct Answer: Option D — does not get too much way on the vessel

A tug pulling at right angles exerts significant sideways force. If the ship's engine is used to generate excessive forward or astern speed, hydrodynamic forces on the hull and towline tension spike dangerously, risking structural parting of the hawser or loss of tug control.
