🔍 Key Concepts

• Rule 29 – Pilot Vessels (Navigation Rules) • Difference between special identifying lights and normal running lights (sidelights and stern light) • Meaning of underway, making way, and at anchor in the Rules

💭 Think About

• Look at what lights a pilot vessel must show to identify herself, then ask: when do the ordinary power-driven vessel lights also have to be added? • Think about whether the requirement changes if the vessel is stopped in the water but not anchored versus when she is actually making way. • Ask yourself: does being at anchor change the light pattern for a pilot vessel compared with being underway?

✅ Before You Answer

• Verify in Rule 29 when the red over white pilot lights are shown by themselves and when sidelights and stern light are added. • Confirm the exact definition of underway (not at anchor, not made fast to the shore, and not aground). • Check if a vessel that is underway but not making way must still show sidelights and stern light under the general Rules for power-driven vessels.
