BOTH INTERNATIONAL & INLAND You are on a sailing vessel. While under sail you decide to use your engine to assist in propulsion. Which of the shapes shown in illustration D016RR below would you exhibit?

Correct Answer: Option D — None of these day signals are correct.

Rule 25(e) requires a conical shape, apex downwards, for a vessel under sail and power. Since the illustration D016RR does not include this specific shape, none of the provided options are correct. The vessel must display the cone to properly signal its status as a power-driven vessel.
