#GALWAY BAY NEWS - Archaeologists in Galway Bay have unearthed an extensive tidal weir complex at Barna and a late medieval quay on Mutton Island, The Irish Times reports.

The weir, which is estimated to date from the early Christian period, consists of a granite barrier with channels cut through it, designed to control the flow of water in the adjacent lagoon.

Connemara archaeologist Michael Gibbons suggests that the weir implies a considerable fish stock migrating through the area into the Barna river.

The remains of a large Iron Age fort which overlooks the site may also have given its name to the townland of Knocknacarra, which is now a populous suburb of Galway.

Meanwhile, further east at Mutton Island a medieval quay which predates the current lighthouse quay has been found.

The Irish Times has more on the story HERE.

#ANGLING - A plaque paying tribute to the late secretary of the Dublin Salmon Anglers' Association has been inveiled at Carton Estate in Co Kildare.
Patrick 'Pat' O'Molloy, who died in November last year, was commemmorated for his pioneering work over the last 35 years in the rehabilitation and restoration of wild salmon stock in the River Liffey, The Irish Times reports.
This involved introducing micro-tagged smolts into the Rye, a tributary of the Liffey upriver of the Carton Estate weir which was impassable from further downstream.
Sadly O'Molloy died before the return of salmon to the Liffey in a year that also saw their return to the Tolka afer more than a century.
Former fisheries CEO Alan McGurdy said at the ceremony: "As you all know, Pat was an angler, a board member, environmentalist, fish farmer and most of all, a friend.
"Today is some recognition to the great man for the tremendous work he did to look after our fish."

Waterways Ireland, as part of a planned inland waterways programme of improvement works, has installed a floating Weir Boom across the weir at Clarendon Lock, Knockvicar on the Shannon Navigation.

Installing the 20m boom was initiated with assembly of the boom off-site in Rooskey. In early December, the drilling for the piles was facilitated by floating a piling rig to the site on pontoons. Piles are required to hold the Weir Boom in place. The boom was then floated to the site and secured in place. The works cost approximately €55,000.

Installation of the boom improves the amenity at Knockvicar in addition to lock gate replacement and upgraded lockhouse facilities which have been completed by Waterways Ireland in recent years.

The Weir Boom is a preventative measure installed by Waterways Ireland to protect boaters and their craft from being drawn over the weir. Space has been left to allow for the passage of canoeists. There will be no environmental impacts on fish or other wildlife from the installation or operation of the Weir Boom.

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.
