🔍 Key Concepts

• Rule 25 – Sailing Vessels Underway and Vessels Under Oars (Navigation Rules) • Difference between sailing vessel under sail alone vs sailing vessel using propelling machinery • Required lights in restricted visibility (sound and light requirements)

💭 Think About

• Think about what lights a sailing vessel of 30 meters must display when underway at night and whether these change just because she is a sailboat. • Consider what extra signals or shapes are required when a sailing vessel is ALSO using her engine (i.e., is technically a power-driven vessel). • Ask yourself: in restricted visibility, do the Rules relax or increase the requirements for showing the basic navigation lights (sidelights and stern light)?

✅ Before You Answer

• Check in Rule 25 what shapes a sailing vessel must show when ALSO using machinery and whether those shapes are shown "forward" or "where best seen". • Verify whether all‑round lights on the mast can replace the stern light on a sailing vessel of 30 m, or if they are optional in addition to the required sidelights/stern light. • Confirm what lights are specifically required for any vessel underway in or near an area of restricted visibility and whether sailing vessels are exempt from sidelights and stern light in fog.
