Abstract
A flagstaff and flag for displaying the flag unfurled in the absence of wind. The flagstaff includes a mast and an attached boom, and a housing with flared spacers underneath the boom. The boom can be attached to a rotary head atop the mast, with openings in the boom, head and mast for a halyard to pass through. The flag is equipped with a head bar to which one end of a halyard is attached. The flag has sliding rings on the side adjacent to the mast and these rings pass around the mast. The flag is raised into position beneath the boom by the halyard which runs from the head bar to the boom and then to the foot of the mast. The head bar may be either outside of the flag or a shaped piece fitting over a rope sewn into the hem of the flag. When in the raised position the head bar rests against flared members in the housing for stability.
