🔍 Key Concepts

• Frapping lines on lifeboat davits and when they are used in the launching sequence • Difference between tricing lines, frapping lines, and gripes • How a lifeboat behaves as it is lowered past the embarkation deck in a seaway

💭 Think About

• Think through the full sequence of launching a lifeboat: when are tricing lines used, and what happens right after that step? • Which lines keep the boat close enough to the ship to board, and which lines control side‑to‑side swinging as it goes down? • Which option describes a normal, routine function during launching—not an emergency improvisation or stowage function?

✅ Before You Answer

• Identify at what point in the launch sequence frapping lines are attached and then released • Confirm which gear (gripes) is specifically for securing the boat in the davits when stowed • Verify that a true safety line function would normally be labeled and described differently than frapping lines in lifeboat equipment lists
