🔍 Key Concepts

• Rule 34 – Maneuvering and Warning Signals (International) – use of lights to supplement whistle signals • Difference between color requirements (white vs yellow) and light characteristics (steady vs alternating/flashing patterns) • Requirement that the light, when used, be an all-round light visible over 360°

💭 Think About

• First decide: for passing intentions, does the rule talk about a color pattern (alternating colors) or simply which single color(s) may be used? • Ask yourself whether the rule allows more than one possible color for this light, or only one specific color. • Focus on whether the rule specifies an alternating pattern (e.g., red/yellow or white/yellow), or just a steady light synchronized with whistle blasts.

✅ Before You Answer

• Check in Rule 34 (b) of the International Rules what colors are explicitly permitted for the passing-intention light. • Verify whether the Rule uses the words “all-round white or yellow” or limits it to only one of those colors. • Confirm that the Rule does not require an alternating color pattern for passing-intention lights, only that the light supplements the whistle and is all-round.
