Modern aerial photography shows the outline of a sunken vessel in the mud at the terminus of the channel (or dock). The craft is aligned with the bank and measures 13m length x 4m breadth. The bow is to the northeast. The vessel's 2-cylinder engine remains insitu towards the stern.

Event and Historical Information:
The BOY HARRY was a two masted ketch built by William Scoble and Jonathan Davies (Scoble and Davies) of Malpas, near Truro, in 1896. Technical specifications are given as 21.36 gt; 52.7ft length x 14.1ft breadth x 5.3ft depth in hold; one deck, two masts, ketch rigged, carvel built, straight stem, framework wood. The ketch was sold to Henry Rogers and Thomas Griffiths in 1903 and re-registered at Milford Haven in 1905 (7 in 1905). Henry Rogers passed away in July 1911 and his shares passed to his wife, Sarah Rogers of The Speculation Inn, Hundleton. From at least March 1917, the vessel is reported to have been working between West Williamston and Pembroke Dock, possibly hired to John Ford, Removal Contractor, Pembroke. In January 1922, the vessel was sold to Agnes Louise Lewis of North Studdock, Angle. Four years later, it was fitted with a 2-cylinder engine and re-registered. The plan accompanying the transcript of an oral history interview with Mr Stanley Arthur (dated 1 June 1971) shows the vessel abandoned in The Gullam. To the south and southwest, four other vessels are shown (WILLIAM AND EMMA, ROSE ELLEN, CHARLIE PEARCE and GOOD HOPE). The testimony suggests that the BOY HARRY was hired for use in the quarry from the time it was part-owned by Thomas Grifftihs. A stone trough, carved from marle stone by the quarrymen, is reported to lie on the bank to the north of the vessel. Stanley Arthur began working at The Croft Quarry and then in The Gullam around 1919-20. The boats working from and owned by the quarries carried stone to Milford, Haverfordwest, Blackpool Mill, Hook, Angle, Sandy Haven and Dale. When tides permitted, two loads per week were taken to the Gas Works Quay in Haverfordwest. This was limestone for burning. At other times, small stones (2in stone, broken down by hand) used for road making and was taken to Dale or Sandy Haven.Very large sandstone blocks were supplied for the building of Hobb's Point at Pembroke Dock. When entering the dock (all canals and cuttings inside the quarries were generally known as docks), the vessels were poled in barge fashion on the first of the tide (15ft-20ft poles being used). The Williamstone quarries stopped working at the beginning of World War II. It is believed that the vessels were laid up before then - around 1937/8.
