🔍 Key Concepts

• IALA Maritime Buoyage System special marks (yellow, "X" topmark) • Difference between light colors and light rhythms/characteristics • Which light rhythms are specifically permitted for special marks

💭 Think About

• First, recall what a special mark is used for and how its light is generally described in the buoyage system. • Look at the four options and ask yourself which are specific flash rhythms often associated with special-purpose buoys. • Think about whether a special mark must have a unique pattern to distinguish it from lateral or cardinal marks, or if it can share common characteristics.

✅ Before You Answer

• Verify in the buoyage table which light rhythms are explicitly listed for special marks. • Check whether a special mark’s characteristic is limited to one type or may include several of the standard flashing types. • Confirm that you are not confusing cardinal mark light rhythms (like very quick or group flashes) with those allowed on special marks.
