Question 63 ONC05 - Master or Mate of LT 200 GRT

The Correct Answer is D **Explanation for Option D (Hoisting cargo aboard a vessel):** A sling, in a maritime or industrial context, is fundamentally a piece of rigging (often made of rope, wire, or synthetic webbing) designed to encompass, secure, and stabilize a load so that it can be lifted, lowered, or moved by a crane, hoist, or derrick. Slings are essential and ubiquitous tools used in the operation of **hoisting cargo** (loading and unloading) aboard vessels. Various types of slings (e.g., net slings, endless slings, basket slings, chain slings) are specifically chosen based on the nature and weight of the cargo being moved. **Explanation for Incorrect Options:** **A) Securing a small boat to a large vessel:** While ropes are used, the process of securing or tying up a boat (mooring, towing, or alongside) is typically done using mooring lines, painters, or towing lines, not generally referred to as "slings." Slings are primarily lifting gear. **B) Hoisting personnel aboard a vessel:** Hoisting personnel requires specialized, regulated equipment (like baskets, certified harnesses, or stretchers) used only in necessary circumstances or emergencies. Standard cargo slings are explicitly **prohibited** for lifting personnel due to safety regulations. **C) Hoisting the anchor:** Hoisting the anchor involves the use of the anchor chain or rode and specialized machinery like the windlass or capstan. While there are components sometimes called "anchor slings" (used for temporary suspension or positioning), the primary operation of hoisting the anchor itself relies on the chain/rode system, not a general cargo sling.
