Question 4963 Deck General

The correct answer is D) The propeller is more susceptible to ice damage when turning slowly than when stopped. The reasoning behind this is that when a ship's propeller is turning slowly, it is more likely to encounter and ingest ice chunks, which can cause damage to the propeller blades. Conversely, when the propeller is completely stopped, it is less likely to encounter and ingest ice, reducing the risk of damage. The other options are incorrect because: A) An icebreaker may be required, but the vessel may also be able to free itself; B) Pumping ballast can be an effective method to free a beset vessel; and C) Clearing the rudder area of ice before backing down is indeed advisable to prevent further ice buildup and damage.
