North East River Marina is a full-service marina on Water Street in Charlestown, with 90 slips for boats from 17 to 42 feet and separate jet ski slips. It rents pontoon boats by the hour or by the day, and Nautical Rentals and Charters, housed on site, offers hourly and daily charters for events. The service department handles OMC, Mercury and Volvo parts, along with canvas and fiberglass repair.
Transient slips are often available by reservation, and bookings are taken by phone. The marina offers summer and winter storage, winterization, shrink wrapping and spring detailing, and its on-site ship's store carries most nautical supplies. It has been voted Cecil County's Favorite Marina in several years from 2015 through 2023. Nearby, there are three restaurants within walking distance and four sandy beaches less than a mile away by water.
