This ship has the pools on deck 16 of 18; outside, but surrounded by sunbath terraces on deck 17. Many Jacuzzi are in the Spa center and in luxury suites, all on the uppermost decks.
It is surprising how small the ship’s movements can be to let the water spill over. With larger movements, the tons of water on deck cannot evacuate around the pools; the water takes the staircases and, with the movements, spreads on the lower decks.
Why didn’t they empty the pools, going into this announced heavy weather?
Someone will need a good explanation.
On the low public promenade deck, water may have entered by the doors, opened by curious passengers, unable to close them again.
