Party for two hours straight on one of Hornblower's Rock the Yacht cruises. Every Thursday through Saturday night, a ship full of revelers departs from Pier 15 for a night of debauchery on the open waves. Dance to the DJ-curated mix of today's top hits along with house music and throwbacks as you snap Instagram-worthy photos of the Manhattan skyline, Statue of Liberty and Brooklyn Bridge. You can even upgrade your ticket to include unlimited beer and wine or access to a premium open bar. Aye aye, captain!
