🔍 Key Concepts

• Load line / Plimsoll mark and what information it shows on a ship’s side • Difference between draft limits and tonnage (a measure of internal volume, not immersion depth) • Purpose of the muster list (station bill) on board a vessel

💭 Think About

• Which of these choices is physically marked on the ship’s hull to show how deep she may safely and legally be loaded? • Which documents deal mainly with the ship’s internal volume and regulatory fees, rather than how deep she sits in the water? • What is the main safety purpose of a muster list, and does it have anything to do with how far the ship may be submerged?

✅ Before You Answer

• Identify which option is actually a hull marking related to safe loading limits. • Eliminate anything that deals primarily with tonnage/volume calculations instead of immersion depth. • Confirm that the remaining choice is the one used by authorities to enforce legal loading and draft limits.
