Blake's Lock, Reading

Reading to Newbury

Navigation should be possible for narrowboats of up to 72ft length, but please consult the waterway office first.

Narrowboats over 70ft long can only pass through Burghfield and Sulhamstead locks diagonally, and should not share with other boats. These locks are to be rebuilt to 72ft x 14ft when finances allow.

Newbury to Bath

Navigation should be possible for narrowboats of up to 72ft length, but please consult the waterway office first.

The chambers of most locks are at least 14ft wide and so can accommodate two narrowboats, though in some instances the gates will not open fully. A few locks in the Caen Hill Flight are slightly narrow - the lock-keeper will advise where this is a problem

Crofton Lock 61 is short and narrowboats over 70ft long may not be able to share with other boats.
