🔍 Key Concepts

• Definition of vessel and inclusion of seaplanes in the Navigation Rules (see Rule 3 – General Definitions) • How a seaplane must behave in relation to other vessels when operating on the water • Whether any special light or status requirements apply to seaplanes compared to ordinary power-driven vessels

💭 Think About

• First, decide whether the Rules treat a seaplane as a vessel when it is on the water. Which option matches that idea? • Look at the choices that talk about speed, lights, or keeping clear. Which one sounds like a general behavior requirement rather than a very specific or unusual condition? • Ask yourself: do the Rules say a seaplane is exempt from being a vessel, or do they fit it into the existing framework of responsibilities?

✅ Before You Answer

• Check the exact wording in Rule 3 – General Definitions about seaplanes operating on the water • Verify whether the Rules assign special lights for a seaplane "not under command" or if that term is reserved for other situations • Confirm whether the Rules talk about a seaplane’s duty relative to other vessels, especially regarding avoiding obstruction or danger
