USCG Exam PracticeRule 30 — Anchored and Aground (lights)

Under the Inland Navigation Rules, a vessel of 18 meters in length is at anchor in a special anchorage area designated by the Coast Guard. Which statement is correct?

  1. A. She must exhibit two all-round white lights as prescribed in Rule 30(a)
  2. She is not required to exhibit the anchor lights or shapes required by Rule 30Correct
  3. C. She may exhibit a single all-round white light only if she is less than 12 meters
  4. D. She must illuminate her decks with working lights

Why B is correct

33 CFR §83.30(g) exempts a vessel of less than 20 meters in length from the anchor light and shape requirements of Rule 30 when at anchor in a special anchorage area designated by the Coast Guard. An 18-meter vessel falls within that size threshold.
