Question 1700 Deck General

The correct answer is A) offshore stern line. The offshore stern line, labeled "A" in the illustration, is used to secure the stern (back) of the vessel to the offshore (seaward) side of the mooring. This line helps to keep the vessel in position and prevent it from drifting away from the mooring. The other answer choices are incorrect because: B) After spring line - This is a line that runs from the vessel's stern to the mooring, but it is not the offshore stern line. C) After breast line - This line runs perpendicular to the vessel's centerline, securing the vessel's side to the mooring. D) Onshore stern line - This would be a line securing the stern to the shore-side of the mooring, rather than the offshore side.
