Are there lock keepers in attendance ?
Yes, most of the time. There are five types of lock in all: a manually operated lock with keeper (the most common type); an electrically operated lock with keeper; and an automated lock with keeper (a type frequently found on major rivers in particular). There are also two other types of lock without a keeper. A manually operated lock without keeper will be found especially on certain canals and rivers which are little used. You and your crew will have to negotiate this lock, whose dimensions are small, but you will be rewarded for your efforts with one of your happiest holiday memories! The automated lock without keeper is often of medium size and can sometimes be found on canals with light commercial traffic. The technician will give you explanatory details of the control system for this at your point of embarkation.
