The Inspectorate of Navigation enforces navigational bye-laws, registers vessels and inspects Waterways Ireland harbours and jetties. The Inspectorate has authority to board craft, impose fines, manage moorings, and order vessel removal. They patrol roads and waterways for safety and compliance.
Start your boating adventure
Owning a boat on the inland waterways is a great adventure. It offers a sense of freedom and excitement that is difficult to match. This page sets out what you need to know to enjoy boating on Ireland’s inland waterways safely and responsibly. You can also find this information in our Voyages and Visits brochure, which is regularly updated.
Getting started
Waterways Ireland oversees 1,000km of navigable waterways, each with its own history and regulations. Expect variations in registration, lock dimensions, rules, operations, and facilities. It’s important to consider these differences before starting your journey. Find out more about the bye-laws, speed limits, bridges, locks and slipways of each waterway below.
Rules of the waterways
Bye-laws are the rules guiding how the waterways should be used. Waterways Ireland, through its Inspectorate, has responsibility for enforcing these bye-laws. Six of the navigations have bye-laws while the Lower Bann has a voluntary code.
Respect harbour rules. Use appropriate mooring lines, avoid trip hazards, give space to other boats and use designated berthing areas. Only secure your craft to the mooring bollards and cleats provided, and don’t berth in a way that prevents the use of safety ladders, slipways or pump-outs. Carry sufficient fenders, make sure your pets are leashed and avoid blocking passenger vessels or lock chambers.
As you travel, please consider the wash of your boat (the wave of water generated by your boat’s engine) and its impact on others. The speed limits on waterways vary, so familiarise yourself with the boating information on each waterway’s webpage.
The Inspectorate uses Marine Notices to draw your attention to navigational and safety issues such as high water levels, areas of danger, maintenance works and closures. Maintenance is usually carried out in winter (1st Nov – 17th March) but pay attention to any notices.

Safety and assistance
We strongly advise you to follow safety recommendations on the water. You can find official guidelines for different activities on the following websites:
- The Department of Transport Ireland,
- The Maritime and Coastguard Agency UK,
- The RNLI
- Water Safety Ireland.
Age restrictions on operating of powered craft
In the Republic of Ireland, you must be over 16 to operate a personal watercraft or fast power craft, and over 12 to operate most pleasure crafts. The owner of the craft is responsible for ensuring compliance.
Lifejackets and Personal Flotation Devices (PFDs)
Wear lifejackets or PFDs when entering or leaving locks, anchoring, coming alongside or departing jetties and quaysides, or when a vessel is towed. The Republic of Ireland has legal requirements regarding the wearing of PFDs. Make sure to read the guidelines.
Sailing Activity
Large numbers of sailing dinghies are present around Lough Derg, Lough Ree and Lower Lough Erne between late June and August. Their courses are marked with yellow buoys. Proceed at slow speed and exercise due caution, following the rules of navigation.
Rowing
Canoes and rowing vessels are present throughout the waterways, and especially around Athlone, Carrick-on-Shannon, Coleraine, Enniskillen and Limerick. Proceed at slow speed and reduce your wash to a minimum. Be prepared to give way in any traffic situation.
Smart Cards
Smart cards are used to operate the locks on the Shannon-Erne Waterway and the Shannon Navigation. They are also used to access the service blocks and use the facilities and pump-outs. Cards are available in either 10 units or 20 units. There is a card reader in each service block where you can check the number of units remaining on your card.
