🔍 Key Concepts

• Hull geometry terms used in ship construction • Difference between longitudinal features (front-to-back) and transverse features (side-to-side) • Where the keel, bilge, and deck edge are located on a vessel

💭 Think About

• Identify which options describe fore‑and‑aft (longitudinal) features versus athwartship (side‑to‑side) or vertical features • Visualize a cross‑section of the ship’s hull at midships: keel on the bottom center, bilge at the turn of the bottom to the side shell, deck at the top • Match the definition: an upward slope of the bottom from the centerline out toward the bilge, not something at the bow, stern, or deck edge

✅ Before You Answer

• Confirm which term is specifically defined as the slope of the bottom plating from the keel toward the bilge • Eliminate terms that relate mainly to the deck shape or the bow/stern profile rather than the bottom • Make sure the term you pick is used when talking about the midship section shape, not the vessel’s ends
