🔍 Key Concepts

• Study the location of the member marked L relative to the turn of the bilge and the outer shell plating. • Recall that a web frame is a deep transverse frame inside the hull, while longitudinals run fore‑and‑aft close to the shell plating. • Remember that a bilge keel is usually an external projection along the bilge to reduce rolling, not an internal stiffener.

💭 Think About

• Is the member at L mainly oriented fore‑and‑aft or athwartships? How does that relate to a longitudinal versus a frame? • Does the member at L look like an internal transverse web, or like a smaller stiffener running parallel to the ship’s length along the side shell? • Which option describes a member that closely follows the curvature of the bilge/side shell where L is pointed?

✅ Before You Answer

• Verify whether the structure at L is inside the hull or an external fin along the bilge (this will help you rule out one option). • Check if the member at L is a single deep web or one of several repeating smaller stiffeners running the length of the vessel. • Confirm that the term you choose correctly matches a member that is primarily fore‑and‑aft and attached to the inner side of the shell plating in that area.
