USCG Exam Practice · Rule 18 — Responsibilities Between Vessels
Rules 11 through 18 of the Inland Navigation Rules apply only under which condition?
- AWhen vessels are operating in restricted visibility
- BWhen vessels are within a traffic separation scheme
- CWhen vessels are in sight of one another✓ correct
- DWhen vessels are within one nautical mile of each other
Why C is correct
33 CFR §83.11 explicitly states that Rules 11 through 18 apply to vessels in sight of one another. 'In sight' is defined in §83.03(k) as when one vessel can be observed visually from the other. Neither radar detection nor proximity alone satisfies this requirement.
