USCG Exam PracticeRule 16 — Action by Give-way Vessel
A power-driven vessel is the give-way vessel in a crossing situation. She takes a series of small course alterations rather than one large maneuver. Which rule does this most directly violate?
- A. Rule 9 (33 CFR §83.09), which requires vessels to keep to the starboard side of a narrow channel
- ✓ Rule 8 (33 CFR §83.08), which requires that alterations be large enough to be readily apparent and that a succession of small alterations be avoidedCorrect
- C. Rule 17 (33 CFR §83.17), which prohibits the give-way vessel from altering course to port
- D. Rule 18 (33 CFR §83.18), which establishes the hierarchy of vessel types
Why B is correct
Rule 8(b) (33 CFR §83.08(b)) specifically states that any alteration of course and/or speed shall be large enough to be readily apparent and that a succession of small alterations should be avoided. The give-way vessel's obligation under Rule 16 must be carried out in a manner consistent with Rule 8.
