INLAND ONLY The masthead light may be...

🔍 Key Concepts

• Inland Navigation Rules – Annex I (Positioning of Lights and Shapes), especially the provision about the masthead light being on the fore‑and‑aft centerline • How power‑driven vessels are normally required to place the masthead light and when an exception is allowed • The special Inland allowance related to vessels with sidelights positioned at the outboard extremes of the vessel’s breadth

💭 Think About

• First, recall the general rule: where must the masthead light normally be placed on a power‑driven vessel? Then ask: which option describes the specific exception to that rule under Inland only? • Look for the choice that describes a configuration of the sidelights and vessel’s breadth, not just the overall length or type of service (like fishing). Which answer actually talks about how the sidelights are carried? • Ask yourself: Does Inland law ever say that just being below a certain length (e.g., under 12 m or 20 m) by itself allows the masthead light to be off the centerline, or is there an additional condition about the sidelights’ location?

✅ Before You Answer

• Verify in Annex I that the default requirement is: the masthead light is on the fore‑and‑aft centerline of a power‑driven vessel • Check which INLAND‑ONLY provision mentions both the masthead light and sidelights carried at the outboard extremes as a reason to allow an off‑center masthead light • Confirm that options referring only to vessel length or vessel engaged in fishing do not describe the specific Inland exception for moving the masthead light off the centerline
