USCG Exam Practice · Danger bearings and danger circles
Under the Inland Navigation Rules, a vessel navigating in restricted visibility detects by radar alone another vessel and determines a close-quarters situation is developing. The detected vessel is forward of the beam. Which alteration of course should the vessel avoid, so far as possible?
- AAn alteration of course to starboard
- BAn alteration of course to port✓ correct
- CAn alteration of course away from the detected vessel
- DAny alteration of course until visual contact is established
Why B is correct
33 CFR §83.19(d)(i) specifies that when taking avoiding action consisting of an alteration of course, an alteration to port for a vessel forward of the beam shall be avoided, other than for a vessel being overtaken. An alteration to starboard is the preferred option in this scenario.
