WWW.FOGOISLE.NL is an operator who dives on HMS Cressy.

Search for "Cressy" or "Kruisers" on their page.
Cressy is one of three Cruisers ("Kruisers") sunk by a single U-Boat (U-9)
on a single morning. Aboukir was hit at 07:20, Hogue at 07:50 and Cressy at
08:35.
At the time (1914), the British were not amused, since the attack happened
even before breakfast: definately "not cricket".
Don't expect too much: most of the wreck is covered with sand. The three
wrecks are within a couple of miles of each other, and usually dive
operators go to "the cruisers", at the very last moment selecting one to
dive on, depending on circumstances (e.g. other vessels on the site: divers,
anglers).
