Thursday 11th February, 8pm – EVERYONE WELCOME

SS Thistlegorm is widely regarded as one of the “top ten” wreck dives in the world. It’s accessibility to recreational scuba divers (the keel lies at 30m) making it a standard inclusion in Red Sea “Northern Wrecks and Reefs” itineraries. Or for those who like early starts(!) it can be dived on a (long) day trip from Sharm el Sheikh or Hurghada.Join us as we hear from Simon Brown of Deep 3D, one of the international team of archaeologists, divers and digital technicians working on The Thistlegorm Project. This is an ongoing underwater archaeological survey recording the remains of the SS Thistlegorm in the Red Sea using cutting edge digital techniques to raise awareness of the wreck and to help ensure its preservation for future generations.

Simon’s talk for us will be based on the session he presented to the Nautical Archaeology Society’s conference in November 2020.Simon’s presentation will cover SS Thistlegorm’s history (archive records), how they mapped it using photogrammetry in 3D, how they used the 3D outputs to identify previously unknown parts of the ship and cargo things…plus some of Alex Mustard’s images to accompany.Digital 2D mapping reveals the wreck in incredible detail – 2mm per pixel across the whole site – which can be measured with confidence.

Since the survey was conducted in 2017 further work has been conducted using more powerful computers which, amongst other things, has located more remains of the locomotives and proved the identity of the parts thanks to some very knowledgeable folk at the Stanier 8F Society. The 2018 Apple iBook has also been followed up in 2020 by a hardback, paperback and Kindle versions which contain updated information. The hardback book is currently available here:…/diving-thistlegorm-ultimate…/

More of Simon’s underwater work can be seen at He also runs, a consultancy and training company that trains police, archaeologists and surveyors in the use of photogrammetry for preservation of evidence and site surveys.
