Under 33 CFR §164.35, a vessel is required to have equipment on the bridge for plotting relative motion. A vessel navigating in restricted visibility detects a radar contact and determines a close-quarters situation is developing. The contact is abeam. Which alteration of course is specifically prohibited by 33 CFR §83.19 when taking avoiding action?
- A. An alteration of course to starboard away from the contact
- B. An alteration of course to port away from the contact
- ✓ An alteration of course toward the vessel abeamCorrect
- D. Any speed reduction while maintaining course
Why C is correct
33 CFR §83.19(d)(ii) prohibits an alteration of course toward a vessel abeam or abaft the beam when taking avoiding action in restricted visibility. 33 CFR §164.35(j) requires bridge equipment for plotting relative motion, which is the tool used to determine the contact's position relative to own ship before executing any maneuver.
