🔍 Key Concepts

• Garboard strake is the shell plating strake that lies immediately alongside the keel on each side of the ship. • On a transverse section view, the garboard strake will be the lowest side shell plate that connects to or lands on the keel plate or centerline bottom plating. • Distinguish between ordinary bottom shell strakes, the keel plate, and the first strake up the side when reading hull-structure diagrams.

💭 Think About

• On this illustration, which plate or strake is directly adjacent to the keel or centerline bottom plating at the turn of the bilge? • Look at the very bottom of the hull: which labeled letter marks the first shell plate that runs fore‑and‑aft along the bottom next to the keel, rather than a transverse floor, frame, or stiffener? • Can you identify which of the labeled parts at the bottom are structural floors, which are side shell plates, and which single one is the garboard strake along the keel? Make sure you are not choosing a side shell strake that is higher up the hull.

✅ Before You Answer

• Verify which line in the drawing actually represents the keel plate/centerline bottom and then locate the shell strake immediately beside it. • Confirm that the letter you choose points to a longitudinal shell plate, not to a transverse floor, frame, or bracket. • Make sure the label you pick is at the lowest part of the hull plating near the turn of the bilge, not one of the higher side shell strakes.
