🔍 Key Concepts

• Sheer as a longitudinal curvature of the deck from midships toward the bow and stern • Effects of sheer on a vessel's seaworthiness and dryness of decks • Difference between structural connection details (butt straps, margin plates) and overall hull form features like sheer

💭 Think About

• Think about how a curved deck line (higher at the ends, lower amidships) would affect how water moves on deck in heavy seas. • Ask yourself whether sheer is mainly about local structural joints (like plate connections) or about the overall shape and behavior of the ship in a seaway. • Consider which option best matches a design feature that helps a ship handle waves and oncoming seas, rather than a detail of steelwork connections.

✅ Before You Answer

• Verify what sheer specifically means in ship construction (shape of deck line vs. plating detail). • Check which choices deal with local structural details (like butt straps and margin plates) and which deal with seakeeping / dryness. • Confirm which function of sheer is emphasized in basic naval architecture texts: strength and seaworthiness at the ends vs. eliminating specific parts.
