Question 817 Rules of the Road

The correct answer is B) the vessel is being propelled by power as well as sail. The shape shown in illustration D035RR indicates that the sailing vessel is being propelled by both power and sail. This is specified in the International and Inland Navigation Rules, which require a sailing vessel using auxiliary power to display this shape when the propulsion power is being used. The other options are incorrect because A) the shape does not indicate the vessel is fishing, C) the shape does not indicate the vessel is on a starboard tack, and D) the shape does not indicate the vessel is close-hauled or having difficulty maneuvering, but rather that it is using both power and sail for propulsion.
