🔍 Key Concepts

• Purpose of dry-docking inspections and what’s typically measured/recorded for future wear comparisons • Which components are expected to wear over time and affect safety or steering (e.g., rudder bearings, stern gear) • Why certain clearances are critical for class/USCG records and alignment checks

💭 Think About

• Ask yourself: Which of these clearances is known to change with wear and is routinely trended over the life of the vessel? • Which item, if its clearance becomes excessive, most directly affects the vessel’s ability to steer safely? • Which clearances are normally checked by class surveyors and shipyard during every dry-docking as a standard item?

✅ Before You Answer

• Identify which option refers to bearing wear rather than just fit between two fixed parts. • Consider which measurement must be repeatable from dock to dock to track progressive wear. • Think about which component’s excessive play would be specifically noted in survey reports and may trigger renewal or repair.
