The coat of arms was granted on 11 September 1987. The official blazon is "Azure, three anchors argent in pall annulets conjoined" (). This means the arms have a blue field (background) and the charge is three anchors. The anchors have a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. The blue color in the field and the anchors were chosen to symbolize the connection that the municipality has with the sea. There are three anchors to symbolize the three smaller municipalities that were merged in 1964 to form the present municipality. The arms were designed by Daniel Rike.
