🔍 Key Concepts

• Freeboard is the vertical distance from the waterline to the main deck; think about which certificate is tied to this safety margin • International load line regulations and markings on the ship’s side (Plimsoll mark) relate directly to freeboard • Different types of certificates: one deals with hull loading limits, one with measurements, one with structural areas like the forecastle, and one with general safety/inspection

💭 Think About

• Which document legally certifies how deeply a vessel may be loaded in various seasons and waters, which is directly determined by its freeboard? • Look at each option and ask: does this primarily deal with how high the deck is above the water and corresponding marks on the ship’s side, or with some other aspect like internal measurements or inspections? • Which of these certificates is specifically tied to the visible marks on the ship’s side that show maximum allowable draft in salt water, tropical, summer, winter, etc.?

✅ Before You Answer

• Match freeboard to the concept of maximum allowable draft and load line marks on the ship’s side • Eliminate any option that mainly deals with survey/inspection of equipment and safety gear, rather than loading limits • Eliminate any option that mainly concerns tonnage measurement or internal volume, rather than the vertical distance from the waterline to the deck
