Before Hurricane Sandy struck, I had read that The Boatel, which occupied Marina 59 would not be returning. The Boatel was a revamping of old boats from the marina, turning them into overnight camping art installations. Apparently all is not lost, and they will be returning in the 2014 season:

If you need a summery fix of sleeping on a boat at Marina 59 this season, it seems you will have a place to turn too. “Truck-A-Float” will be outfitting Marina 59 with floating boat like structures that will be available for nightly rental.
