Practical

Covered and uncovered slips for vessels up to 65 feet, in and out service, land storage for boats up to 30 tons, petrol and diesel. Bath houses, on-site laundry, a shaded pavilion with picnic tables and grills, and a ship's store stocking beer, wine and snacks.

St. Clement's Island State Park lies about half a mile offshore, reachable by tender or seasonal water taxi. A 40-foot cross raised in 1934 marks the spot.

History

Coltons Point faces St. Clement's Island, where Leonard Calvert and the first Maryland colonists came ashore from the ships Ark and Dove on 25 March 1634. Father Andrew White celebrated the first Catholic mass in the British colonies there that day.
