The largest dive access only water-locked wedding ceremony consists of 69 people, and was achieved by Jani Santala (Finland) and Ina Traelnes (Norway) in Mo I Rana, Norway, on 10 August 2019.
54 guests attended the wedding, as well as 13 technical crew members and the bride and groom. All attendees had to scuba dive through 100+ metres of water to reach the cave where the wedding ceremony took place. The newlyweds were also greeted by the Mayor once they reached land!
