The LYC Burgee
a flag bearing the colors or emblem of a sailing club, typically triangular.
A burgee is a distinguishing flag, regardless of its shape, of a recreational boating organization. In most cases, they have the shape of a pennant.
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.
