Navigation:
The Great Machipongo Inlet leads between Hog Island and Cobb Island to Great Machipongo Channel. Shoals on either side of the entrance are marked by breakers at all times; the bar breaks only in heavy weather. The inlet is marked by buoys that are shifted in position with changing channel conditions.
The Great Machipongo Channel extends northwestward through Hog Island Bay from the inlet to the mainland where it continues as Machipongo River.
Willis Wharf on the west bank of Parting Creek 1 mile above the junction with Machipongo River, is a base for shellfish and fishing boats.
