Welcome to the website of the Inland Waterways Association of Ireland (IWAI), a voluntary organisation that advocates the use, maintenance, protection, restoration and improvement of the inland waterways of Ireland. IWAI was founded in 1954 and is on-line since '99.

Inland waters are any area of water, such as canals, tidal and non-tidal rivers, lakes, and some estuarial waters, not categorised as ‘sea’.

IWI brings together people and organisations who support the conservation, use, development and proper management of inland waterways worldwide.

Since 2008 IWI’s World Canals Conference Site Selection Steering Committee has been choosing the site to host the annual World Canals Conference, from the applications submitted. The committee is currently chaired by Rory Robinson.

We found charts in spiral bound form which had the same waterway information as our digital charts as well as maps of the land surrounding. Together they equated to our digital charts and the road atlas. But we never found a list of harbous with details and facilities.

Another  document we failed to find was an overview chart of the inland waterways of Germany which listed depth and air draft. We purchased an <link> overview chart which showed us the routes but not the depths and the minimum bridge height on that route. In the Netherlands there is the Standemaast Route chart produced by ANWB which supplies this for the country.

Note : The German language pilot books we used for the Mitteland Canal, the Rhine, the Mosel and the Main, all of which are published by Delius Klassing, are woefully out of date. As we got further into the trip we realised that the books were consistently out of date and had not been updated either via new edition or via online addendum documents. Harbours listed didn’t exist, harbours we used were not listed, depths were often imaginary, descriptions of facilities were like old pictures and had not been updated. For the price charged the Delius Klassing publications were poor value but we didn’t find much alternative.
