USCG Exam PracticeRule 8 — Action to Avoid Collision
Rule 8 states that a succession of small alterations of course and/or speed should be avoided. Which of the following best explains the intent of this requirement?
- ✓ Small incremental changes may not be readily apparent to another vessel observing visually or by radar, reducing the effectiveness of the avoiding action.Correct
- B. Small alterations consume more fuel and reduce vessel efficiency.
- C. Small alterations are prohibited because they violate the stand-on vessel's right to maintain course and speed.
- D. Small alterations are only permitted when directed by a vessel traffic service.
Why A is correct
33 CFR §83.08(b) requires alterations to be large enough to be readily apparent to another vessel observing visually or by radar, and expressly states that a succession of small alterations should be avoided. The concern is detectability and clarity of intent, not fuel use or VTS authority.
