🔍 Key Concepts

• Chart scales and what "large scale" vs "small scale" means • Typical use of harbor charts vs coastal or general charts • How the written phrases "not less than" and "not more than" affect the size of the scale number

💭 Think About

• Think about whether a harbor chart needs to show a lot of detail in a small area, or a broad overview of a large area. • Compare which options represent the largest scale (i.e., most zoomed‑in) versus smallest scale (most zoomed‑out). • Ask yourself: for close‑quarters pilotage in a harbor, would you want a ratio with a larger second number or a smaller second number?

✅ Before You Answer

• Verify which scales are considered large‑scale (more detail) versus small‑scale (less detail). • Check how the phrases "not less than" and "not more than" change the meaning of the numerical scale limits. • Confirm which type of chart (harbor, coastal, general, sailing) normally has the highest level of detail for navigation.
