Jamestown

Jamestown is on the east side of Conanicut Island in a bight on the west side of East Passage. A standpipe in the southern part of the town and a hotel near the waterfront are prominent. The bight is a popular summer anchorage for local craft.

From the south, the approach to Jamestown utilizes the East Passage, the principal passage in Narragansett Bay, which extends between Rhode Island on the east and Conanicut and Prudence Islands on the west. It is the most direct route to Newport, Bristol, Providence, Mount Hope Bay, and Taunton River.

Prominent Features
Brenton Point is the southwestern extremity of Rhode Island and the eastern entrance point of East Passage.

Brenton Reef, bare in places, extends 0.5 mile south-southwestward of the point and is marked by a gong buoy. Another reef extends 0.5 mile offshore just eastward of the point; Seal Rock is at the southeastern end of the reef.

Seal Ledge, about 0.5 mile south of Seal Rock, has depths of 12 to 30 feet and is marked by a bell buoy. Haycock Ledge, 0.4 mile eastward of Seal Rock, has a least depth of 11 feet.

Beavertail Point is the southern extremity of Conanicut Island, on the western side of the entrance to East Passage. Beavertail Light (41°26'58"N.,71°23'58"W.), 64 feet above the water, is shown from a square granite tower attached to a white dwelling at Beavertail Point. A fog signal is at the light. Several antennas and radar towers are north of the light. Newton Rock, a covered rock, is about 0.1 mile southward of the point; a bell buoy is about 0.2 mile southwestward of the rock.

Mackerel Cove indents the southern shore of Conanicut Island about 1.6 miles northeastward of Beavertail Light. A house with a cupola is prominent on Southwest Point, the eastern entrance point of the cove. The cove is exposed to southerly weather and is seldom used. The Jamestown Bridge shows prominently over the bar at the head of the cove on entering East Passage. Kettle Bottom Rock, about 0.2 mile southeastward of Southwest Point, is bare and marked by a gong buoy.

Bull Point, the southeastern point of Conanicut Island, is rugged and rocky, and fringed by shoals, which are marked by buoys. Fort Wetherill is on the point. The Dumplings, northeast of Bull Point, are numerous bare and covered rocks and islets. The most southerly islet has a tall house on it, covering almost the entire islet.

Marine Facilities
A marina basin protected by a detached breakwater is in the center of the bight. Jamestown has two boatyards. The largest marine railway can handle craft to 80 feet, and the largest lift is 50 tons. Berths, electricity, gasoline, diesel fuel, water, ice, some marine supplies, and complete hull, engine, and electronic repairs are available.
