🔍 Key Concepts

• Chart lettering styles (upright/vertical vs. sloping/italic) and what they indicate on NOAA/US charts • How hydrographic (underwater) features are usually labeled compared with land/topographic features • Relationship between how a rock is shown (symbol + name style) and its reliability/visibility

💭 Think About

• Ask yourself: On standard nautical charts, are underwater and drying dangers usually written in vertical (upright) or sloping (italic) letters? • Consider whether the style of lettering is used to show visibility with the tide, or to show whether the feature is related to the land or to the water. • Think about which option describes something that would reasonably be communicated by text style alone, without extra symbols like ‘PA’ (position approximate) or drying heights.

✅ Before You Answer

• Check a copy of U.S. Chart No. 1 (or its legend) for the explanation of upright vs italic lettering. • Verify how doubtful positions are actually shown on charts (clues: look for ‘PA’, ‘PD’, dotted circles, etc., not just text style). • Confirm whether tidal visibility of a rock (dry at HW, visible only at certain tides) is normally indicated by the rock symbol and sounding/drying height, not just by the font of its name.
