Yacht clubs and their members may fly their club's burgee while under way and at anchor, day or night. Sailing vessels may fly the burgee either from the main masthead or from a halyard under the lowermost starboard spreader. Most all powerboats (i.e., those lacking any mast or having a single mast) fly the burgee off a short staff at the bow; two-masted power vessels fly the burgee at the foremast.
The officers of a yacht club may fly various burgees appropriate to their rank: for example, the commodore may fly a swallow-tailed version of the club burgee (and the vice- and rear-commodores the same, but distinguished by the addition of one or two balls respectively at the canton). A past-commodore may also be given a distinctively-shaped flag.
