Cotswold Archaeology was commissioned in February 2016 by Historic England to undertake a marine assessment for possible de-designation of the Brighton Marina designated area. The wreck is believed to be the remains of a 16th century vessel, possibly built in continental Europe, and was designated to ensure high standards of archaeological recording and ensure that those carrying out the work had the necessary resources to do so. This assessment will be based on desk-based research, geophysical survey and diver survey; this report presents the results of the desk-based research and geophysical survey.
