USCG Exam Practice · Rule 35 — Sound Signals in Restricted Visibility

A vessel of 15 meters in length is at anchor in restricted visibility. Which statement correctly describes her sound signal obligations under Inland Rule 35?

  1. AShe must ring the bell rapidly for about 5 seconds at intervals of not more than 1 minute.
  2. BShe is not obliged to give the bell signal but must make some other efficient sound signal at intervals of not more than 2 minutes.✓ correct
  3. CShe is not obliged to give any sound signal because she is less than 20 meters in length.
  4. DShe must sound one prolonged blast followed by two short blasts at intervals of not more than 2 minutes.

Why B is correct

33 CFR §83.35(i) provides that a vessel of 12 meters or more but less than 20 meters in length is not obliged to give the bell signals prescribed in paragraphs (g) and (h), but if she does not, she shall make some other efficient sound signal at intervals of not more than 2 minutes. A 15-meter vessel falls within this category.
