USCG Exam PracticeRule 23 — Power-driven Vessel Underway (lights)
A WIG craft is taking off at night. In addition to the lights prescribed in Rule 23(a), what additional light must she exhibit?
- A. An all-round flashing yellow light where it can best be seen
- ✓ A high-intensity all-round flashing red lightCorrect
- C. Two all-round red lights in a vertical line
- D. A high-intensity all-round flashing yellow light
Why B is correct
33 CFR §83.23(c) requires a WIG craft, only when taking off, landing, and in flight near the surface, to exhibit a high-intensity all-round flashing red light in addition to the lights in paragraph (a). The all-round flashing yellow light in option A is prescribed for air-cushion vessels in non-displacement mode under §83.23(b), not for WIG craft.
