This is a series of posts that answers to the questions from the ONE15 Brooklyn Sail Club’s skipper’s certification test:
When a Sailboat Considered a Powerboat?
When a sailboat > 12m is under power during the day, it shall display an cone shape.
During the night, a sailboat shall also display a masthead light.
If your outboard is tilted down – it is presumed you are under motor. To avoid confusion, when under sail, tilt the engine out of the water so others know that you have no auxiliary power.
Remember when a sailboat is under power, obey all the COLREGs for motorized vessels.
