Forty-six hours before Rüdiger Koch officially seized the Guinness World Record for the longest time spent living in an underwater fixed habitat, I took a 15-minute motorboat ride from Linton Bay Marina, in north-central Panama, to visit him. It was a warm afternoon in January, and Koch was approaching a full 120 days spent working, eating, sleeping, drinking and smoking cigars in a room 36 feet below the surface of the Caribbean.
His 304-square-foot habitat was inside the underwater buoyancy chamber that helps stabilize a floating home called SeaPod Alpha Deep. An armed security guard was in the above-water part of the structure, monitoring Koch and ensuring that the pod did not have “any visitors that we don’t want.” When my boat arrived, he threw down a cable and winched me up. Then I made my way down a 63-step spiral staircase to the circular lower chamber — a dizzying process, as the SeaPod rocked in the loudly sloshing sea. I was greeted by a beaming Koch, a bald 59-year-old German engineer with a whitened beard and a Buddha belly.
