Please note that the lights shown below are legal for a sailing vessel under 7 metres. However - the same lights can also represent other vessels. The stern of every power vessel looks exactly like this! So do many vessels at anchor. However these lights are legal for a “less than 7 metre” and based on a single all-round white light.
