USCG Exam PracticeRule 28 — Constrained by Draft (lights)
A power-driven vessel is towing astern and the length of the tow, measured from the stern of the towing vessel to the after end of the tow, is 215 meters. Which of the following correctly describes the masthead light requirement for the towing vessel?
- A. Two masthead lights in a vertical line
- ✓ Three masthead lights in a vertical lineCorrect
- C. One masthead light forward and one masthead light aft, as for a normal power-driven vessel
- D. Two masthead lights in a vertical line and one all-round white light
Why B is correct
33 CFR §83.24(a)(i) states that when the length of the tow exceeds 200 meters, the towing vessel shall exhibit three masthead lights in a vertical line instead of the normal masthead light(s). At 215 meters the tow exceeds 200 meters, so three lights are required.
