Last week we posted on the fateful cruise of a 23-foot Titanic replica on Lake Pontchartrain. Fateful because of the traffic jam it caused on the Lake Pontchartrain Causeway. Well, yesterday’s Times-Picayune (Save the Picayune!) had a front-page expose on the replica’s owner, Mark Koch. I mention him here because he is apparently quite the shipwreck enthusiast. Koch, a commercial diver, has also spent some time “combing the Gulf of Mexico for shipwrecks.” According to the T-P article, Koch is quite the collector of “shipwreck kitsch” (for lack of a better term). He also owns the only two lifeboats known to exist from the Andrea Doria, a luxury liner that sank off the coast of Nantucket in 1956. Incidentally, Koch purchased both the Titanic replica and Andrea Doria lifeboats on eBay! Ah, the wonders of eBay.
