A roller band display for displaying nautical symbols on a ship comprises first and second rollers 102a,b. The rollers are configured to support a banner 110 having a plurality of symbols. The banner is wound around the rollers such one of the symbols of the plurality of symbols is positioned for display in a display window 122 between the first roller and the second roller. An actuator is provided to rotate at least one of the rollers to control which of the plurality of symbols is visible in the display window. The banner may be double-sided to display symbols on both sides of the display. Identifiers 118, e.g. RFID tags, may be provided on the banner for automatically determining by means of a suitable reader 120 which of the symbols is visible. The display is especially for use with uncrewed surface vessels (USV) so that the display of appropriate nautical symbols may be controlled remotely.
