Broken wreck dive with swim-throughs and seals.
Slack-water timing and war-grave etiquette are best handled with local Cork support.
The Chicago is a broken Cork Harbour wreck with swim-throughs, recognizable machinery, and a reputation for close seal encounters. It is a straightforward wreck dive rather than an intact liner, so the appeal is the structure, the machinery, and the busy life around the hull. Plan the dive around slack water and keep a calm pace through the broken sections. It is best treated as a cold-water historic wreck where tide timing matters more than depth alone.
