🔍 Key Concepts

• Load Line Zones and Seasonal Marks – how summer and winter load line marks limit how deeply a ship may be loaded in different zones • Most Restrictive Condition – whether you must comply with the most restrictive (higher freeboard) mark anywhere on the voyage • Fresh Water Allowance – how loading in fresh water versus salt water affects your draft/freeboard when you go to sea

💭 Think About

• Think about which load line mark controls your maximum loading when your route passes through a more restrictive zone than your departure and arrival ports. • Ask yourself what your draft must be when you enter the winter zone, and whether that draft requirement limits how much you were allowed to load at port A. • Consider what the question says about port B being a summer port: does that allow you to arrive deeper than the winter mark if you had to pass through a winter zone on the way?

✅ Before You Answer

• Identify which is more restrictive: the summer or winter mark, and what that means for maximum allowable draft. • Check whether a vessel may ever be deeper than the mark that applies to the most restrictive zone encountered on the voyage. • Verify how fresh water allowance changes draft from pier side (fresh/brackish water) to salt water at sea, and whether that can temporarily put you over any applicable mark.
