BOTH INTERNATIONAL & INLAND What is the maximum length of a power-driven vessel which may show an all-round white light and sidelights instead of a masthead light, sidelights and a stern light?

🔍 Key Concepts

• Rule 23 – Power‑driven vessels underway (International & Inland) • Special lighting option for small power‑driven vessels using one all‑round white light plus sidelights • Difference between masthead/stern lights vs a single all‑round white light

💭 Think About

• Look up the exact size limit in Rule 23 where it says a power‑driven vessel may, in lieu of the standard masthead and stern lights, show one all‑round white light and sidelights. What length does it mention? • Compare the length limit in the rule to each option. Which choice is just under that limit when expressed in meters with one decimal place? • Think about typical cutoff sizes in the Rules (e.g., 7 m, 12 m, 20 m, 50 m). Which of the answer choices most closely matches a well‑known small‑vessel breakpoint related to navigation lights?

✅ Before You Answer

• Verify in Rule 23(d) (International & Inland) the exact length in meters for this special lighting arrangement. • Confirm that the rule applies specifically to a power‑driven vessel underway, not sailing, not at anchor, and not restricted in ability to maneuver. • Make sure the option you choose is the one that is just below the stated limit in the rule (for example, "less than 12 m" would correspond to 11.9 m as a typical exam conversion).
