USCG Exam Practice · Rule 6 — Safe Speed

Under the Inland Navigation Rules, which of the following is NOT listed as a factor that a vessel with operational radar must additionally consider when determining a safe speed?

  1. AAny constraints imposed by the radar range scale in use
  2. BThe effect on radar detection of the sea state, weather, and other sources of interference
  3. CThe draft of the vessel in relation to the available depth of water✓ correct
  4. DThe more exact assessment of visibility that may be possible when radar is used to determine range

Why C is correct

33 CFR §83.06(a)(vi) lists draft in relation to available depth of water under paragraph (a), which applies to all vessels, not as an additional radar-specific factor under §83.06(b). Options A, B, and D are all listed in §83.06(b) as additional factors for vessels with operational radar.
