🔍 Key Concepts

• Different barge types and what cargo they are designed for • Why certain cargoes like coal, gravel, or scrap may not need weather protection • How the shape/structure of a barge (open top vs flat deck vs tank/barge sides) relates to its name

💭 Think About

• Which option best describes a barge that carries bulk cargo in a recessed space where cargo is piled in, rather than stacked on a flat deck? • Look at the word parts in each choice: which one suggests an uncovered cargo area suited for bulk material that can get wet? • Which terms (single skin/double skin) relate more to the number of hull layers for safety/tankage instead of the cargo area type?

✅ Before You Answer

• Identify which choice clearly indicates an open top or uncovered cargo hold • Eliminate answers that mainly describe hull construction rather than cargo arrangement • Confirm which barge type you’d expect to see carrying coal, sand, or gravel on inland rivers
