Marinas in Edgewater, MD

The best all-around time is June through early September on Edgewater’s South River and the adjacent Chesapeake Bay, when the water is warm. Maryland DNR measured South River surface water in the low 80s in August 2026. Local access is not confined to summer: Beverly Triton Nature Park is open seven days a week except Thanksgiving and Christmas, but weekend and holiday reservation passes apply from Memorial Day weekend through Labor Day weekend.

Weather and tide still decide whether it is a good day. Treat thunder or lightning as a reason to get off the water, and check NOAA’s Edgewater, South River tide predictions before departure.

From Edgewater, you can boat the South River, Selby Bay, Glebe Bay, Rhode River and the Chesapeake Bay. The South River opens to the Bay through a marked channel; many coves and creeks have marked minimum-wake or 6-knot areas. Selby Bay has a shallow southern end, while Glebe Bay is generally deeper but has shoals in midbay and along its sides. Rhode River is reached from the Bay through West River and has marked shoals off its points. Powerboats use local small-craft facilities around Edgewater and Selby Bay; hand-carried boats can launch at Mayo Beach Park or Beverly Triton Nature Park.

Boaters from Edgewater can head to Annapolis City Dock and Ego Alley for waterfront dining, downtown shops and watching boats turn through the basin; Galesville on the West River for a dockside meal and harbor views; and the Rhode River anchorages around High Island and Flat Island for a protected stop on the hook. NOAA describes the Rhode River as a popular boating rendezvous and identifies the island areas as especially popular, while local tourism pages present City Dock and Galesville as waterfront visitor stops.

Maryland does not issue a recreational boating license, but people born on or after July 1, 1972 generally must carry a boating safety education certificate when operating a numbered or documented pleasure vessel. This includes personal watercraft, whose operators must be at least 16. Anyone under 16 operating a motorized vessel 11 feet or longer without a certificate must instead be supervised by someone 18 or older who holds a valid certificate, or who was born before the cutoff. Exemptions include commercial operators, qualifying visitors, private waters, and those born before the cutoff. Renters of motorized vessels other than personal watercraft may be issued a 10 day temporary certificate after reading a safety sheet. Maryland Natural Resources Police administers the program.

Maryland boaters should know the state’s life jacket, alcohol, registration and personal watercraft rules, enforced by the Maryland Department of Natural Resources and Natural Resources Police. Children under 13 must wear a Coast Guard approved life jacket while underway on a recreational vessel under 21 feet; children under 4 need added infant safety features. Operating while impaired is illegal, and an alcohol concentration of 0.08% is considered boating under the influence. Mechanically propelled vessels used most in Maryland during the calendar year must be registered. PWC operators must be at least 16, wear an approved life jacket and may not operate between sunset and sunrise.

Maryland sets no general minimum age for operating a motorized vessel other than a personal watercraft, but an operator under 16 is never unsupervised. Under Natural Resources §8-712.2, someone under 16 must both hold a boating safety certificate and have an eligible supervisor aboard. For vessels under 11 feet, the supervisor must hold a certificate; for vessels 11 feet or longer, the supervisor must hold one and be at least 18. Someone born before July 1, 1972, may also supervise.

Personal watercraft operators must be at least 16 and carry a certificate if born on or after July 1, 1972. The rental operator sets its own minimum, so confirm it when booking.
