The correct answer is C) The "Free and Proceed" system of escorting a beset vessel cuts down on the number of freeing operations. The "Free and Proceed" system is a method used by icebreakers to escort beset vessels through ice fields. This system involves the icebreaker creating a channel for the beset vessel to follow, rather than repeatedly freeing the vessel from the ice. This reduces the overall number of freeing operations required, making it a more efficient way to navigate through ice. The other options are incorrect because: A) Towing a vessel through ice is sometimes necessary and recommended in emergency situations. B) Increasing the scope of the anchor chain is not advisable in icy conditions, as it can lead to the anchor becoming buried in ice. D) Anchoring in the presence of ice is not recommended, except in emergencies, as the ice can damage the anchor and chain.
