In waterfront communities, teenagers with tricked-out boats have to go to the marina to do donuts before towing in after curfew. Find a space with full view of the landless logistics with today's Groupon: for $25, you get $50 worth of transient docking at Cape Ann's Marina Resort in Gloucester.

Located inside Gloucester Harbor on the Annisquam River, Cape Ann's Marina Resort offers seafaring citizens more than 275 slips to dock and refuel their boats as well as prime spots for picnics, grilling, and taking in the busy sights and sounds of an active marina. Transient docking ($3.50/ft. per day through September 13) offers ship captains and levitating yogis safety and security when storing their respective vessels. Dock any boat up to 100’+ at one of the slips, then recite an ebullient rendition of "To the Harbormaster" before making use of the indoor pool, restrooms, and showers located on-site. The marina is located within walking distance of many beaches, shopping districts, and historic sites, including the very place Benjamin Franklin came to escape from the city and dream up the electric toaster.
