The "main pool" on the ground floor is 50 m by 20 m with a maximum depth of 2 m. A sinkable boom can separate the pool into a 23 m by 21 m with constant depth between floor level and 2 m depth; and a 25 m by 21 m section at 2 m depth, which in turn can be separated by another sinkable boom to allow a section of 10 m by 21 m. The floors of these 3 sections can each be independently raised or lowered between very shallow and 2 meters depth.
