Question 2331 Deck General

The correct answer is B) swing line. A swing line is a line used to temporarily position or maneuver a barge or other vessel into the desired position, such as to make up a tow. By attaching the swing line to the stationary barge and pulling it, the vessel can manipulate the barge's position as needed. The other options are incorrect because: A) a check line is used to temporarily secure a vessel, C) a jockey line is used to adjust the towing bridle, and D) a fore and aft line runs longitudinally along the length of the vessel, rather than being used to position a barge.
