USCG Exam PracticeRule 23 — Power-driven Vessel Underway (lights)
A WIG craft is in flight near the surface at night. In addition to the lights required for a power-driven vessel underway under Rule 23(a), what additional light must she exhibit, and under what conditions?
- A. An all-round flashing yellow light at all times when underway
- ✓ A high-intensity all-round flashing red light only when taking off, landing, and in flight near the surfaceCorrect
- C. A high-intensity all-round flashing red light at all times when underway
- D. An all-round flashing yellow light only when taking off and landing
Why B is correct
33 CFR §83.23(c) requires a WIG craft to exhibit a high-intensity all-round flashing red light in addition to the standard power-driven underway lights, but only when taking off, landing, and in flight near the surface — not at all times when underway. The all-round flashing yellow light is prescribed for air-cushion vessels, not WIG craft.
