The largest boat tie-up consisted of 1,651 boats and was organized by the Lake Cumberland Association (USA) on Lake Cumberland, Kentucky, USA, on 14 August 2010. Eligible boats included any motorized boat, aquabike/jetski, canoe/kayak and rigid inflatable boat tied together in a single, continuous structure. Nine marinas along the lake combined to register participants in the "raft-up" event, which saw boats tied together beginning at 10 a.m. and lasting until 6 p.m.
