In this episode of Speaking Sidemount, brought to you by XDEEP, Steve Davis reacts to and analyses the 2021 wreck-diving tragedy inside the wreck of HMS Scylla off Plymouth, UK. This is Steve's reaction to Dom Robinson's interview with Adam Dent, the sole survivor of this tragic dive. https://www.youtube.com/watch?v=OMYKjZocins&t=1996s On the dive in question, two divers lost their lives during a 3 Deck penetration dive inside the wreck of HMS Scylla. Steve examines the dive from the perspective of: • A wreck diving instructor• A technical sidemount, CCR Cave and Full Cave, and advanced wreck diver • A former Royal New Zealand Naval Officer and Marine Engineer Officer of HMNZS Canterbury, a Leander-class frigate of the same generation as HMS Scylla.• Author of the book "The Canterbury Wreck – A Diver’s Guide" Drawing on his years of experience serving aboard Leander-class frigates, his training and wreck diving experience, plus hundreds of dives on the Canterbury wreck, Steve discusses how the layout of a warship influences wreck-diving navigation and why advanced wreck protocols are critical when penetrating deep into wrecks. Topics discussed include: • The difference between recreational and "Advanced Wreck" diving• Why shipwrecks become labyrinths underwater• Advanced wreck diving planning• The importance of progressive penetration• Guideline use and its limitations• Other methods of wreck diving navigation, such as strobes and the “lines of the wreck”• The human factors that contribute to wreck diving accidents• What to do if you become lost inside a warship.This episode is not about criticism.
