The locks on the river are paired, with two lock chambers side-by-side, and in most cases the larger lock also has intermediate gates, so that ships of varying length can be accommodated, without undue waste of water.
The maximum size of the locks is 196 by 35 feet (60 by 11 m) above the Anderton boat lift, and 213 by 37 feet (65 by 11 m) below it.
The lock at Weston Point Docks is slightly narrower, at 213 by 36 feet (65 by 11 m).
The boat lift is designed for canal craft rather than ships, and so can hold vessels up to 72 by 14 feet (21.9 by 4.3 m) with a draught of 4 feet (1.2 m).
