These are the remains of a large riveted vessel, built around the turn of the 20th Century. The shape of the hull suggests that the vessel may have been a steamship rather than a sailing ship. Damage apparent on the hull indicates the reason why the ship sank. This damage may have been caused by shells, a torpedo or a collision. Sidescan sonar - steamerSite WA 1002 was first discovered in 1974, and is located 13.5nm south of Shoreham, West Sussex at a depth of 49m. The dimensions are approximately 63m x 8-10m x 5-6m, although the vessel may be longer since the stern is badly damaged. Wessex Archaeology surveyed the site in 2005 using multibeam sonar, sidescan sonar and magnetometer. As a result, the site was interpreted as a large wreck lying on its starboard side. The site was re-surveyed a year later using a ROV (remotely operated vehicle), confirming the original UKHO identification.

After comparing the survey results to documentary evidence, records indicate four possible ships that could be the remains from WA 1002: Peter der Grosse, Gotthard, Polpedn and Houlgate. More information about the site can be found by visiting the Wessex Archaeology pages dedicated to this wreck site, including the site layout, construction, and possible identification of the vessel.
