BOTH INTERNATIONAL & INLAND Which is TRUE for a self-propelled dredge NOT engaged in dredging, but proceeding to a dredging location at night?

Correct Answer: Option B — be required to show the lights of a power-driven vessel underway

Rule 27(d)(vi) specifies that a vessel engaged in dredging or underwater operations, when not actually engaged in the work, shall exhibit the lights or shapes prescribed for a power-driven vessel underway. It does not retain the special lights of a dredge unless it is actively performing the restricted operation.
