What does the underwater hull report consist of?

• A. Visual inspection and quantitative measurements
• B. Photo gallery only
• C. Visual aids only
• D. No data

Answer: (A)

Underwater hull surveys rely on both what you can observe and the measurements you take. The report should document visual findings—like corrosion, damage, fouling, and deformation—along with quantitative data gathered with gauges and instruments, such as thickness readings and other objective measurements. This combination provides a record you can compare over time and use to assess remaining life and priority for repairs. A folder with photos alone lacks the numeric baseline needed to judge severity, and a report with only visuals or no data is not actionable.
