The largest underwater wedding was achieved by 303 divers who attended the marriage ceremony between Ewa Staronska and Pawel Burkowski (both Poland) during an event organised by Orka Group Ltd (Poland) at the Koparki Diving Base, Jaworzno, Poland, on 27 August 2011.
The wedding ceremony lasted around 18 minutes and was preceded over by Father Pawel Wrobel, a local priest and licensed frogman. The couple and the priest communicated with each other underwater by using water proof texts and a system of sign language.
