- ✓ By using radar to determine the range of vessels or other objects in the vicinityCorrect
- C. By measuring the back scatter of the vessel's own lights against the radar return
- D. By cross-referencing the number of radar contacts with the vessel traffic density
Why B is correct
33 CFR §83.06(b)(vi) states that a more exact assessment of visibility 'may be possible when radar is used to determine the range of vessels or other objects in the vicinity.' This is the specific mechanism identified in the rule.
