Cape Cod Canal is a deep-draft sea-level waterway that extends westward from Cape Cod Bay to the head of Buzzards Bay. The waterway has a project depth of 32 feet and a least overhead clearance of 135 feet. The eastern entrance to the canal is marked by a lighted 244°54′ range, lighted and unlighted buoys, a light and a sound signal. A tall strobe-lighted stack and buildings of the powerplant on the south bank of the canal about 0.75 mile above the eastern entrance, is prominent.
The canal shortens the distance between points north and south of Cape Cod by 50 to 150 miles and provides an inside passage to avoid Nantucket Shoals.
Traffic lights (red, green, and yellow) are located at the easterly canal entrance at Sandwich; at the Canal Electric Terminal basin on the south side of the canal at Sandwich; and at the westerly entrance of Hog Island Channel at Wings Neck. These signals apply to all vessels over 65 feet in length.
Cape Cod Canal Breakwater Light 6 (41°46’47″N., 70°29’23″W.), 43 feet above the water, is shown from a red cylindrical tower on the end of the north breakwater at the east entrance to Cape Cod Canal from Cape Cod Bay. A sound signal is at the light. The most prominent landmark when approaching from Cape Cod Bay is the tall lighted stack of the powerplant about 1.1 miles west-southwestward of Cape Cod Canal Breakwater Light 6. The high-level highway bridge across the canal at Sagamore, 2.5 miles west of the breakwater light, is also prominent. The breakwaters at the east entrance to the canal should not be confused with the smaller jetties at Sandwich Harbor, 1 mile to the southeastward.
Federal project provides for a channel 32 feet deep through the Cape Cod Canal. The canal is lighted at night on both banks by mercury vapor lights, generally 500 feet apart.
The Cape Cod Canal is crossed by three bridges. The railroad bridge at the village of Buzzards Bay, 7.8 miles above Cleveland East Ledge Light, has a vertical-lift span with a clearance of 7 feet down and 135 feet up. The span is normally maintained in the raised position and lowered for the passage of trains. The State Route 25/28 highway bridge at Bourne, 9 miles above Cleveland East Ledge Light, has a fixed span with a clearance of 135 feet. The U.S. 6/State Route 3 highway bridge at Sagamore, 11.8 miles above Cleveland East Ledge Light, has a fixed span with a clearance of 135 feet.
Due to the strong tidal currents in the canal, especially during spring tides, low-powered vessels should await slack water or favorable current. Navigators are warned to be on the alert for possible bank suction and bank cushion, the effects of which may cause a vessel to take a sudden and decided sheer.
