Your Wash
You are asked to consider the wash of your boat and its effect on others. All engine-powered boats create a wave of water, known as a wash, which flows outwards from the boat as it moves forward. Look behind you frequently to check the effect that your wash is having on other users. You are advised to reduce your speed in narrow channels to prevent bank erosion, damage to reed beds and destruction of birds' nests among reed and bank habitats. Slow down where boats are moored, when approaching quays, jetties or locks or where water activities are taking place.
Fuel Points
Fuel is available from garages adjacent to the canal.
Maintenance Works
Maintenance works on the waterways are, where possible, carried out during the winter. When navigating any waterway between 1 November and 17 March you are advised to contact Waterways Ireland Operations Division or the Inspectorate before making your journey to confirm that the waterway is open.
Entrance to the Royal Canal from the Sea
Entrance to the Royal Canal is via the River Liffey and the sea lock at Spencer Dock.
