🔍 Key Concepts

• Ship structural members in the double bottom area • Names and locations of strakes and plates near the turn of the bilge • Difference between plates along the centerline versus plates at the ship’s side

💭 Think About

• Picture a transverse cross-section of a double‑bottom ship: where is the ‘inner bottom’ and what part lies closest to the shell plating at the ship’s side? • Which term is commonly used for the plate that forms the boundary between the inner bottom and the side shell plating? • Which of these options refers to something that ‘finishes off’ or ‘edges’ the inner bottom rather than an extra reinforcing or replacement plate?

✅ Before You Answer

• Identify which option is specifically associated with double-bottom construction and the inner bottom boundary at the side shell • Eliminate any terms that usually refer to reinforcement plates or filler/transition plates in plating seams • Confirm that your choice describes the plate that runs along the outer edge of the inner bottom, adjacent to the side shell
