Canal MooringBoats will have mooring ropes, and also a hammer and steel mooring pins. Its free to moor almost anywhere on the (towpath) side of canals. Generally there will often be a sign if mooring is not allowed. Remember not to moor by turning places, near locks, on tight bends, and any other places where you might get in the way of other boats. Often on the opposite canal side the land is privately owned, and thus mooring is not permitted.
It is a good idea not to put your pins too far in from the canal side and block the towpath, and some people even tend to put something coloured on top of the pins so that when its dark walkers can still see them. So that it doesn't move around too much when passed by other boats, you should ensure you tie the boat up fairly tight.
