USCG Exam PracticeDanger bearings and danger circles
Under 33 CFR §164.35, which combination of equipment is required on the bridge specifically to support collision avoidance plotting?
- A. An echo depth sounding device and a gyrocompass repeater
- ✓ A marine radar system and equipment on the bridge for plotting relative motionCorrect
- C. An ARPA and a continuous depth recording device
- D. A gyrocompass and a rudder angle indicator
Why B is correct
33 CFR §164.35(a) requires a marine radar system for surface navigation, and §164.35(j) requires equipment on the bridge for plotting relative motion. These two items together directly support collision avoidance plotting. ARPA requirements are addressed separately under 33 CFR §164.38 and apply only to vessels meeting specific gross tonnage thresholds.
