Waterways Ireland advises masters of vessels on the Lower Bann navigation that infrastructure maintenance works at Carnroe Lock, south of Coleraine in Northern Ireland, are under way as of Thursday 1 December and are expected to continue until March 2023.

These works will necessitate the closure of the lock and therefore navigation through Carnroe Lock will not be possible during this period, the cross-border body for Ireland’s inland waterways says.

Over the next six weeks these works will comprise replacement of the middle lock gates in this double-chamber lock and associated works.

Waterways Ireland advises users of the Grand Canal Greenway that the section from Digby Bridge to Sallins in Co Kildare will be closed from Monday 28 November to Tuesday 20 December in order to facilitate the restoration of the Four Pots overflow structure.

The Four Pots is a unique overflow structure located alongside the Grand Canal towpath between the Leinster Aqueduct and Digby Bridge, the cross-border body for Ireland’s inland waterways says.

No longer in use, this ingenious overflow system has four circular channels of varying depth that helped reduce the water pressure and volume rate before discharge from the canal back to the River Liffey through a series of channels.

Waterways Ireland have shared their enthusiasm at once again being a part of Science Week, which runs this year from Sunday 13 to Sunday 20 November.

The Learning Zone website will host ‘Explore Ireland’s Waterways’, an online workshop which takes you on a virtual visit of exploration to your local canal, river or lake.

This workshop is full of fun and interesting activities covering a range of topics ideal for either classroom based or outdoor learning, the cross-border body for Ireland’s inland waterways says.

What is biodiversity? Do you know what the words species, habitat of ecosystem mean? Check out the Waterways Wildlife Fact File to find out more about the diverse variety of wildlife found within our waterways.

Our waterways are a haven of biodiversity. It’s very important that we all respect these environments while we enjoy the benefits they offer. The Waterways Hero!! activity highlights the importance of being a responsible waterway user.

Make you own Waterway Eco-Dial to bring it on a nature walk or watch the Explore Ireland’s Waterways video to identify some of the plants & animals living along your local waterway

You can also make the most of the last of the autumn leaves with the Autumn on the Waterways tree-creation activity.

Explore these and much more in the Waterways Ireland Learning Zone during Science Week 2022 this week.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
