Question 4114 Deck General

The correct answer is A) draws more water than when underway in deep water. This is because of the phenomenon known as "squat," which occurs when a deep-draft vessel navigates in a narrow channel or canal. As the vessel moves through the confined waterway, the water flow around the hull is restricted, causing the vessel to sink deeper in the water. This increased draft can pose a significant hazard if the vessel approaches the channel's bottom or sides, increasing the risk of grounding or collision. The other options are incorrect because B) a higher speed would actually increase the squat effect, drawing more water, C) steering ability is generally reduced in confined waters due to the squat phenomenon, and D) the power required for a given speed would actually increase due to the additional resistance from the confined waterway.
