Question 4168 Deck General

70% to pass

When underway and proceeding ahead, as the speed increases, the pivot point tends to _______________.

A move lower
B move aft
C move forward
D remain stationary
AI Explanation

The correct answer is C) move forward. As the speed of a vessel increases, the pivot point (the point around which the vessel turns) tends to move forward. This is because as the speed increases, the hydrodynamic forces acting on the hull and propeller cause the vessel to behave more like a projectile, with the center of rotation moving closer to the bow. This forward movement of the pivot point is a well-established principle in ship handling and is an important consideration for navigating and maneuvering vessels, especially in confined waterways. The other options are incorrect because: A) the pivot point does not move lower as speed increases, B) the pivot point moves forward, not aft, and D) the pivot point does not remain stationary as speed increases.
