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?
- AAny constraints imposed by the radar range scale in use
- BThe effect on radar detection of the sea state, weather, and other sources of interference
- CThe draft of the vessel in relation to the available depth of water✓ correct
- 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.
