#CoastalNotes - Heavy rains last week caused the latest in a series of landslides that has cut off a coastal village in Co Kerry, as TheJournal.ie reports.

Only pedestrian access is currently permitted on the Cliff Road to Rossbeigh after a partial collapse of the roadside into the sea on Thursday (17 September).

But the cliff fall is no surprise to locals who have complained for the last two years over increasing erosion caused by various heavy rains and severe storms.

#CoastalNotes - Solutions to deal with the erosion of Ireland's coastline to not have to cost "millions", a geography lecturer tells The Irish Times.

The comments by University College Cork's Dr Max Kozachenko follow a less heartening scenario described by fellow UCC academic Prof Robert Devoy, who said last month that erosion rates - exacerbated by increasingly extreme weather - will soon force Ireland's coastal counties to look "very clinically" at what parts are most worth saving via expensive engineering works.

However, Dr Kozachenko says that such a take-it-or-leave-it solution is "simplistic" when a co-ordinated approach involving coastal monitoring and new approaches to managing the effects of wind and wave action could stem the damage to Ireland's coastline for little expense.

He cites the placing of rock fragments in front of protective rock armouring or concrete walls to scatter waves and dissipate their energy as a cheap but effective option, and also notes the success of offshore artificial reefs in Japan that have had the added benefit of assisting in biodiversity.

#Coasts - Increasing coastal erosion and weathering will soon force Ireland to make hard decisions about what parts of the coastline are too expensive to protect, according to a university professor.

As The Irish Times reports, Prof Robert Devoy of University College Cork says that with erosion rates threatening to jump far beyond the current average of up to 1 metre a year, Ireland's coastal counties would have to look "very clinically" at what parts are most worth concentrating their engineering efforts - expensive measures that simply cannot be afforded for all coastal areas.

The senior lecturer in the UCC Department of Geography says: "We need to assess which bits of the coast are most vulnerable to flooding and erosion and which bits of coast from a heritage viewpoint are important to retain and protect."

This sobering warning comes after Lorna Siggins' commentary on the state of Ireland's coastal marine environment, as six new marine protected areas are set to be enacted in law.

The six sites around the coast earmarked for designation as Special Areas of Conservation were proposed by Heritage Minister Jimmy Deenihan more than a year ago

But as Siggins states: "There’s turbulence ahead, if the State’s approach to fulfilling the habitats directive on land is anything to go by."

Aside from the "inconsistencies, poor communication and lack of stakeholder engagement" of the likes that have undermined bog conservation efforts, there's also the "survival of the fittest" attitude among the fishing fleet engendered by uneven implementation of the Common Fisheries Policy to contend with.

And according to Siggins, even the reformed CFP spearheaded by Marine Minister Simon Coveney will do "little to protect sensitive spawning grounds".

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.
