A 22-meter sailing vessel when also propelled by machinery shall show during daylight hours a ________.

• A. Black cone
• B. White ball
• C. Red square
• D. Blue pennant

Answer: (A)

Day shapes communicate a vessel’s status to others during daylight. A sailing vessel that is also propelled by machinery is operating as a power-driven vessel in addition to sailing, so it must display the day shape that indicates this mixed mode. The designated shape for a sailing vessel underway with auxiliary engine is a cone, shown at the masthead so other vessels understand that you may be maneuvering under power as well as under sail. The other options don’t fit this status: a white ball marks a vessel at anchor, while red square and blue pennant are not the day shapes specified for a sailing vessel with engine.
