For operations in pack ice, a vessel should _______________.
AI Explanation
The correct answer is D) have a drag of not more than 2 to 3 feet.
For operations in pack ice, a vessel should have a shallow draft to avoid getting stuck or damaged by the ice. A drag (the distance between the waterline and the lowest part of the vessel) of not more than 2 to 3 feet is recommended to allow the vessel to navigate safely through pack ice. This is because a deeper draft could cause the vessel to get caught on the ice, leading to potential damage or getting stuck.
The other options are incorrect because: A) being on an even keel is not as important as having a shallow draft, B) ballasting the vessel to have the forefoot near the surface may not be necessary, and C) trimming the vessel slightly by the head could actually increase the draft and make it more prone to getting stuck in the ice.
