Sea Lock and the canal basin are currently being restored by the present owners. The lock was large enough to allow river barges and small seagoing craft that could pass under Bideford Long Bridge to enter the canal basin and remain there for unloading or repairs.
The Torridge estuary has a large tidal range and upstream of Bideford there is no navigable channel when the tide is out.
The canal had to be above the highest tide level to avoid flooding by sea water, so a lock was required to enable ships to enter the canal basin whenever there was enough water in the river.
