USCG Exam PracticeLeeway allowance in plotting
A vessel is navigating in a traffic separation scheme. When crossing a traffic lane, the vessel shall cross on a heading as nearly as practicable at what angle to the general direction of traffic flow?
- A. 45 degrees
- ✓ Right angles (90 degrees)Correct
- C. As small an angle as practicable
- D. Parallel to the traffic flow
Why B is correct
33 CFR §83.10(c) states that a vessel obliged to cross a traffic lane shall do so on a heading as nearly as practicable at right angles to the general direction of traffic flow. This maximizes visibility of the crossing vessel's intentions to traffic in the lane.
