The Lucy (Wreck)

 ship wreck, interesting place, invisible

The men who crew ships which carry calcium carbide are wise enough to abandon them when seawater starts to make contact with their cargo writes Kendall McDonald. Seawater plus carbide makes acetylene gas, which makes for exploding ships.
So the crew of seven and the ship's collie dog were in a liferaft and clear of the 450-ton Dutch coaster Lucy very quickly after she hit Blackstones Reef in Jack Sound, at midday on 14 February, 1967. She was on her way from Norway to Barry, South Glamorgan.
The 52m-long Lucy, with her carbide cargo now fizzing as the water rose inside her, remained balanced on the reef until early evening when the rising tide lifted her off. She was last seen drifting away into St Brides Bay with a heavy list to starboard. A snowstorm drew a curtain over her last moments, as she sank on the north side of Skomer Island, right in the heart of the Skomer Marine Reserve.
She served only three years as an ocean going vessel, but as one of the most dived wrecks in Wales, her useful life for divers is guaranteed to be far longer
