Dear all, In 2018 recreational scuba divers from Southsea Sub-Aqua Club were granted permission by the French Culture Ministry (DRASSM) to conduct a project to survey, record and research the wrecks of British Catherine Class minesweepers HMS CATO, MAGIC and PYLADES. These ships were lost to German 'Human Torpedo' whilst defending the British eastern anchoring area.. Our survey report can be found on our club web site Southsea Sub-Aqua Club - Project CATO and includes photographic/sonar images as well as research into the loss. Our thanks to Chris Howlett, Danny Lovell and others for their help. We hope you enjoy the report and would be delighted to hear from anyone with an interest or information on these ships. Ali
