The Greenpoint Aqua Condo...Boat?

So, we're walking along in Greenpoint after shooting some photos of McCarren Park and Karl Fischer Row (aka Bayard Street), when we notice the Aqua Condo has finally lost some of its scaffolding and black netting. As we get closer we notice...a boat on top of the scaffolding at the corner. Seems to be taking the water theme at the Aqua a bit far, but it certainly makes for a most interesting visual. Anyone knows what the boat is doing there, please do share.
