The line buoy has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

Sande is composed of many islands including Sandsøya, Kvamsøya, Voksa, Riste, and part of Gurskøya (which is shared with neighboring Herøy).

The municipal council (Kommunestyre) of Sande is made up of 21 representatives that are elected to four year terms.
