LOCK DISTANCE POSTS
For working boat crews, time was money: when two boats met at a lock, this led to disputes over who was there first – and fighting between crews was common. So canal companies installed marker posts equal distances each side of a lock: the first boat past the post had the right to the lock. Boaters were expected to sound their horn or whistle ( or crack their horsewhip) when they passed the post. What was to stop them sounding it early? Nothing really, so perhaps this was more of a case of ‘being seen to be doing something’ than an actual solution – but the posts are still to be seen on the Oxford ( pictured) and southern Grand Union.
