Question 615 Deck General

The correct answer is D) hoisting cargo aboard a vessel. A sling is a device used to lift and move objects, such as cargo, using a crane or other hoisting equipment on a vessel. Slings are specifically designed for the safe and efficient transfer of loads from one location to another on a ship or boat. The other answer choices are incorrect because they do not accurately describe the primary purpose of a sling. Hoisting the anchor, hoisting personnel, and securing a small boat to a larger vessel are not the main functions of a sling on a vessel.
