Joseph F. Carven Sr. State Boat Ramp in Weymouth provides public access to Back River and Hingham Bay for both recreational and commercial boaters.

The ramp serves as a critical launch point for rescue operations by MEMA and State Police, and ensures all residents can access the waterways regardless of private marina membership.

The ramp's navigability depends on periodic dredging of the Back River channel, with the most recent dredging completed in 1998.
