Waterways Ireland advises masters of vessels on and users of the Shannon Navigation that the lifting bridge at Tarmonbarry in Co Roscommon will now reopen on Friday 3 May.

This extension of the bridge’s closure since February is a result of additional repair works required following a bridge strike.

The cross-border body for Ireland’s inland waterways says it apologises for extending this closure “but the additional work is essential to ensure the bridge is safely operational in advance of the bank holiday weekend”.

A diversion route remains available via the Camlin River.

Waterways Ireland advises masters of vessels on the Shannon Navigation that in-river works for the construction of the Killaloe Bypass upper bridge superstructure are progressing as planned and will continue until October 2024.

As previously reported on Afloat.ie, the bridge is being constructed around 1km downstream of the current Killaloe–Ballina bridge.

A buoyed navigational channel continues to be provided for 100 metres either side of the in-river works.

The following plant and equipment will be operating on or overhead the navigation during the upper bridge works:

  • 600t crawler crane set up on the east shore
  • Stabilising crane barge (30m x 23m x 1.88m)
  • 100t crawler crane
  • Tugboat/pusher boat
  • Dumb barge (23m x 9m) and mobile elevated work platforms
  • Safety boat
  • Landing pontoon and gangways

From next Tuesday 2 to Friday 19 April, the final steel girders will be lifted into position in the central spans of the bridge.

This is a heavy lift operation and deemed high-risk work, requiring calm waters for operation of mobile elevated work platforms (MEWP) on barges.

Masters of vessels are requested to proceed at slow speed (5 knots, no wash) with additional caution in the vicinity of the works, and to follow the instructions of the safety boat crew as there are hazards such as bridge piers, steel piles and mooring lines to navigate.

The cross-border body for Ireland’s inland waterways thanks its customers for their cooperation in relation to these works.

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.
