Development
Freediving
Due to its depth, Dean's Blue Hole is the site of a number of free diving world records.[2]
In April 2010, New Zealander William Trubridge broke the world record reaching a depth of 92 m without the use of fins.[4] Trubridge operated the Vertical Blue freediving competition[6] at Dean's Blue Hole.
In July 2025, Walid Boudhiaf, set a new Tunisian national record of 118 m at Vertical Blue 2025.[7] The 2025 competition featured 20-odd divers including Trubridge, Alenka Artnik, Alice Modolo, Arnaud Jerald, and Filippo Carletti.[7]
One free diver, Nicholas Mevoli, however, died at Dean's Blue Hole in November 2013 attempting to set a new American national record.[4][8]
