The lightship Sevenstones marks the Sevenstones Rocks, a dangerous reef off the Isles Of Scilly.
Sevenstones was manned originally by a crew of ten keepers, with five on station at a time. She has been unmanned since 1987. The accommodation and storage was taken out and replaced with foam so that she would stay afloat in the event of a collision. On several occasions she has broken free of her moorings, so is now secured by 550m of heavy chain to a 4t anchor.
The lamp flashes white 3 times every 30 seconds, and is visible for 40km. The fog signal sounds 3 blasts every 60 seconds.
