🔍 Key Concepts

• Review the definition of a seam in shell plating (a fore‑and‑aft joint between plates in the same strake) versus a butt (a transverse joint). • Look closely at how the outer hull plates are arranged: some joints run vertically, others run horizontally or around the turn of the bilge. • Note which labeled arrows point to the joint between plates, and which point to stiffeners, frames, or the plates themselves.

💭 Think About

• On the outer side shell, which labeled letter is pointing specifically at the long joint where two adjacent plates meet along the ship’s length, rather than at the plate surface or an internal frame? • Among E, H, L, and M, which labels are clearly attached to internal framing members (girders, floors, or web frames) that would not be called seams in plating terminology? • Compare one vertical joint between plates and one horizontal joint; which orientation matches the definition of a seam for shell plating?.

✅ Before You Answer

• Make sure the option you choose is pointing at a joint between two shell plates, not at a single plate or an internal beam/frame. • Confirm that the joint indicated runs fore‑and‑aft (longitudinally) along the hull rather than transversely. • Verify that letters L and M appear on internal structure (frames, longitudinals, or girders) and can therefore be eliminated as seams.
