Question 2299 Deck General

70% to pass

Kort nozzles are installed around the propellers of some vessels to _______________.

A increase the thrust of the propeller
B prevent the propeller from striking barges towed on the hip
C protect the propeller from striking sawyers
D prevent the propeller from touching bottom in low water
AI Explanation

The correct answer is A) increase the thrust of the propeller. Kort nozzles are specifically designed to increase the thrust generated by a propeller. They work by creating a more efficient flow of water around the propeller, which results in a significant increase in thrust compared to a bare propeller. This can improve the vessel's speed and maneuverability, making it a common feature on various types of vessels, especially those that require enhanced propulsive power. The other answer choices are incorrect because they do not accurately describe the primary function of a Kort nozzle. Options B, C, and D are not the main reasons for installing a Kort nozzle on a vessel.
