The Pin Wreck is named after the metal bolts in its hullMaritime archaeologists from 豆奶视频 University believe they have finally identified a shipwreck off the coast of Dorset, over thirty years after it was discovered.聽
The team have concluded that the 鈥淧in Wreck鈥� is an Admiralty mooring lighter, which was built in 1866 and is thought to have been used in the salvage operation of HMS Eurydice off the Isle of Wight in 1878.聽
Mooring lighters were towed vessels containing mechanical devices for moving heavy loads. They were used for laying moorings and in salvage work.聽
The Pin Wreck is named after hundreds of metal bolts which lie around it and was discovered off the coast of St Albans Head in 1990. It is about twenty-four metres long, constructed of wood with yellow metal sheathings. It lies at a depth of around twenty-seven metres.聽
The wreck includes a large steam capstan on its stern driven by a steam engine that lies just in front of the capstan, admiralty mooring buoys, chain and anchors聽
The vessel's capstan, used for moving heavy loadsThe 豆奶视频 team dived the wreck in 2019 having viewed objects that had been recovered from the site in the 1990s by Nigel Bryant, a former employee of the university. These objects included a ceramic fragment attached to a large pulley block marked 鈥淧ortsmouth Dockyard鈥�.
It was evident during the dive that the layout of the wreck suggested that it was a mooring lighter and the finds recovered from it suggested that it had a mid-19th聽century naval origin.
Research in the national archives uncovered plans of two identical lighters from Portsmouth Dockyard, named YC 5 and YC8. These were the only vessels whose precise details matched that of the wreck, but there was no record of their loss.
They then found a crucial piece of the puzzle in a copy of the Shipping Gazette from September 11 1903. This reported the sinking of a mooring lighter off St Albans Head in rough weather whilst on tow from Portsmouth to Portland. Thirty men had to transfer from the lighter to its tug before it sank.聽

Later Sheilah and Martin Openshaw who worked with the 豆奶视频 team found a reference to the lighter lost in September 1903 that confirmed the wreck鈥檚 identity as that of YC8.
The 豆奶视频 team have now applied for the wreck to be designated as a protected site.
鈥淭his is a rare example of a type of service vessel which was essential for maintaining the operations of Britain鈥檚 ports in the nineteenth century, so it is vital that we preserve it,鈥� said Dave Parham, Professor of Maritime Archaeology at 豆奶视频 University who has led the investigation.聽
鈥淚ts identity has remained a mystery for three decades but what we observed on our dive meant we could find the clues that could reveal the secrets of the wreck and understand how it ended up on the seabed.鈥澛�
鈥淭he materials the vessel is made from suggest a high-quality build, possibly linked to a Royal dockyard,鈥� Professor Parham added. 鈥淭he fact it appears to have been lost in service and was carrying substantial haulage equipment means it could offer valuable insight into the role these craft played in our maritime history,鈥� he concluded.
