Met Éireann says the progress of Hurricane Lorenzo this week and any potential impacts for Ireland “are being closely monitored”.

The powerful weather system, which is currently threatening the Azores in the mid-Atlantic, was recently the most easterly Category 5 hurricane on record, surpassing Hurricane Hugo 30 years ago.

Forecasts beyond the next 48 hours “still of low confidence given the uncertainty” of the storm’s current behaviour.

Numerical prediction models currently show a wide spread of outcomes for the storm track ranging from Greenland to the north of France.

As of today (Monday 30 September) it’s expected that Lorenzo will transition into an “extra-tropical depression” between noon and midnight on Wednesday 2 October.

Met Éireann says its most likely path after this transition brings it to the northwest of Ireland without making landfall.

However, even at that it “still brings the risk of severe winds, possibly stormy conditions and very high seas”, as Met Éireann’s Deirdre Lowe told BreakingNews.ie.

Latest updates will be provided on the Met Éireann website HERE.

The weather warning issued by Met Éireann for Co Clare has been upgraded to the most severe Status Red as Storm Hannah is expect to brings gusts of up to 150km/h this evening (Friday 26 April).

Meanwhile, the marine warning has been upgraded to Status Orange, as cyclonic variable winds will increase to gale Force 8 or strong gale Force 9 on Irish coastal waters from Howth Head to Mizen Head to Rossan Point and on the south Irish Sea during this afternoon and evening.

Winds are forecast to reach storm Force 10 to violent storm Force 11 this evening and early tonight between Carnsore Point and Slyne Head.

The extreme weather has seen the cancellation of sailing and watersport events nationwide, including rowing’s Limerick Regatta which had been scheduled for tomorrow.

#StormFionn - Met Éireann has issued a Status Orange marine weather warning for all coasts of Ireland and on the Irish Sea today (Tuesday 16 January) as Storm Fionn sweeps in.

Westerly gales or strong gales with mean speeds of up to 80km/h and gusts of as much as 120km/h are forecast for all coastal waters, increasing to storm force from Roches Point to Slyne Head to Malin Head later this afternoon, this evening and tonight.

Donegal, Galway, Leitrim, Mayo, Sligo, Clare, Cork and Kerry are under a Status Orange wind warning till late tonight, with much of the rest of the country under Status Yellow for mean wind speeds of between 55 and 65km/h and gusts of around 100km/h expected.

The sixth winter storm of the current season comes two weeks after Storm Eleanor, the brunt of which was felt in Donegal and Northern Ireland.

#StormEleanor - Just days after Storm Dylan swept across the north of Ireland, winter storm number five is set to move in off the Atlantic later this afternoon (Tuesday 2 January).

Met Éireann has issued a Status Orange weather warning for Munster, Leinster, South Galway and for small craft in all Irish coastal waters as the storm system moves quickly across the country this evening, with southwest to west winds of mean speeds of 65 to 80 kmh, gusting to 110 to 130 km/h.

Gale to stormforce south to southwest winds will veer westerly on all coasts of Ireland and on the Irish Sea, with a risk of violent Force 11 winds briefly on some western and eastern coasts and on parts of the North Irish Sea.

#Weather - Barely a month after Storm Caroline, a Status Orange gale warning is in effect on all Irish coastal waters and on the Irish Sea as Storm Dylan is forecast to sweep over the country this evening (Saturday 30 December).

South to southwest games or strong gales are expected to develop around the coast tonight, reaching storm force in western areas, with a Status Yellow small craft warning also in effect.

Met Éireann says the expected track of the fourth winter storm of the current season is north-eastwards through Donegal Bay and along the North Coast.

The biggest impact from the storm will be across Connacht and Ulster, where west to southwest winds will hit with mean speeds of 60 to 80 km/h with gusts of up to 120km/hr. High seas along the west coast are also expected, with the risk of coastal flooding.

The national Status Orange wind warning applies from 9pm this evening till 6am tomorrow (Sunday 31 December) in all counties of Connacht; Cavan, Monaghan and Donegal; Longford, Louth, Meath and Westmeath. A Status Yellow warning is in place for all counties in Munster, and Leinster counties Dublin, Carlow, Kildare, Kilkenny, Laois, Wexford, Wicklow and Offaly.

#Weather - Met Éireann has issued a Status Yellow gale warning on all Irish coastal waters and on the Irish Sea in effect from 5am this morning (Wednesday 6 December).

Gusts of up to 110km/h are expected along all coastal areas today ahead of Storm Caroline’s passage over the North West and North towards Scotland on Thursday.

High winds will affect parts of Scotland, but the storm system — the third of the current winter storm cycle — will also generate strong and blustery winds over Ireland.

Northwest winds of 55 to 65 are expected to gust 100 to 110 km/h, with the strongest winds in coastal areas and over high ground.

The severe weather comes almost two months after the near-hurricane Ophelia devastated many parts of Ireland.

In this digital age, with so many available resources providing sea area weather forecasts, is there still a need for national radio to broadcast these forecasts?

I heard an RTE Radio Presenter asking a Met Eireann meteorologist on-air whether there was any point in broadcasting weather forecasts for the marine sector any more, because there was so much detailed weather information available online.

It reminded me of the battles I had with RTE Radio managers and schedulers when they came up with their idea of ending such weather forecasts altogether, because they took up broadcast time which could better used.

I was Marine Correspondent with RTE then so the conversation a few weeks ago between the RTE Presenter and Met Eireann reawakened my memories of those internal RTE disagreements and underlined for me how badly served the maritime sector is by the national media, both broadcast and print.

It also underlines why the BBC Radio Shipping Forecasts are popular amongst Irish fishermen, mariners, professional, commercial and leisure – because it’s a specialised service to the marine sector that RTE doesn’t provide in the same way.

The coastal radio stations of the Coast Guard give weather forecasts which are available at sea, thankfully, but the mindset of the RTE Presenter showed it was closed to around Dublin and Montrose and unaware of the reality of life, particularly in the maritime sector and the coastal communities, outside of urbanisation.

The Met Eireann Meteorologist told the RTE Presenter that there are coastal areas around the Irish shorelines and at sea where there is no internet access and not even a reliable mobile phone signal and that there is still dependence on the State broadcaster for the forecast.

That is a viewpoint I agree with, but one could add that the ‘independent broadcasters,’ those who are also described as national ‘commercial stations’ should also consider.

There has been a demand from the non-State public service broadcaster for a share of the licence fee, but that should also bring responsibilities, such as a sea area forecast for mariners.

A former hyper-active hurricane, only very recently re-classed as a severe tropical storm, hits southwest Ireland at dawn from south of southwest on a mid-October Monday morning writes W M Nixon. It spends the entire day tracking destructively across country, until it finally departs from our island to the northeast.

It sounds like the demented scenario for a majestic blockbuster movie. Such a mega-film would use special effects to get the full impact of the various disasters which arise as this Enemy of the People – personalized by being called Storm Ophelia - does her worst to provide extreme conditions in which people (inevitably a cast of thousands) will dramatically respond in their many and various ways, some truly selfless, others anything but.

It would definitely be a big budget production. We can know that for certain. For on this post-storm morning, with weather of surreal and gentle beauty after Ophelia has gone on her way, the cost of clearing, repair and re-build will surely run to many millions when all is finally put right, which will certainly be months rather than days or weeks.

Yet how have we as a people and an island nation emerged from it? The feeling is encouraging. There seems to be a heightened sense of ourselves in a fairly benign light, an awareness that when push comes to shove, our infrastructure and emergency services can rise to the challenge, provided all the people of Ireland quietly help them by not making unreasonable demands for their assistance.

For sure, three deaths is three deaths too many, particularly as in two cases it involved the victims helping others. But in the wholesale felling of trees, the destruction of property with the particularly horrible risk of flying debris, and in the hour after hour of the flooding of rivers and the battering of coasts and harbour with boats at risk everywhere, people took expert advice and generally kept themselves as much as possible out of harm’s way.

And this of course is where we realize how much things have moved on from our previous experiences of extreme weather conditions. Meteorology has advanced so much with short-term forecasts achieving such precision that those who had business out of the house which simply had to be dealt with knew to within half an hour when they absolutely had to be back safely indoors.

So Met Eireann now has even more respect as a National Treasure. As for the comforting presence of a sensible stream of practical advice from the National Emergency Co-ordination Group (NECG), that was exactly what was needed to encourage everyone to be sensible and avoid unnecessary risks, while its Chairman Sean Hogan has become the nation’s poster boy for “Keeping Calm in the Midst of Storms”.

With the main drama being played outdoors, inevitably there were those who had to take on risky repair and remedial work in exposed places at the scene of damage, and the rest of us were lost in admiration for the Electricity Service teams. Most of us know little enough about how electricity works in the first place, yet these guys not only has to know it in life and death situations, but they had to be skilled foresters and tree surgeons as well as they went about their highly dangerous tasks.

Rosslare yacht opheliaConditions were extremely challenging with force nine winds with a six metre sea swell when Rosslare RNLI went to rescue this yacht in the Irish Sea

Finally, there’s the episode of that rescue by the Rosslare Lifeboat of a yacht in distress at the height of the storm. Some day we’ll learn just how the yacht was there at all, for heaven knows Ophelia had been well signaled for days in advance. But oddly enough, that’s not too important this morning, What is important is that Cox’n Eamonn O’Rourke and his crew – all volunteers – were assembled within minutes, they carried out a text-book rescue with clinical precision, and the country could return to keeping itself safe for the day, as we’d been advised to.

Because although there’d been some grumblings that the warnings beforehand were surely tending towards exaggeration, they weren’t. The three tragic deaths were three deaths too many, and infinitely sad. But yesterday could have been a continuing litany of personal tragedies if people had deluded themselves that they could have got away with cheating such a prodigious force of nature.

So we emerge from our encounter with Storm Ophelia with a heightened sense of ourselves as a mature nation. Ireland is unique – a medium-sized island on the leeward side of one of the roughest oceans in the world. Our population is such that we have to stretch resources to provide the services and expertise which countries with larger populations can take in their stride.

Yet when Storm Ophelia tested those services, Ireland was not found wanting. And we Irish conducted ourselves like sensible adults who will accept a certain amount of discipline when it is presented to us in a competent and reasonable manner.

On this, the day after the storm, we can feel quietly proud of being Irish.

The Coast Guard advises caution to public as Met Éireann warns of heavy swell on Atlantic Coast later on Sunday.

Members of the public have been urged to heed the advice of the Coast Guard as Met Éireann has issued a status yellow wind warning with some very strong west, veering northwest winds expected to affect western and south western coastal counties later Sunday, overnight and into Monday morning with very high seas along the coasts during this period.

The Coast Guard advises the public to be careful on exposed coasts, cliffs and piers, harbour walls and promenades along the Atlantic seaboard particularly at high tide.
Remember to Stay Back, Stay High and Stay Dry.

If you see someone in difficulty in the sea, on the shore dial 999/112 and ask for the Coast Guard.

Say Hello to Storm Jake

Storm Jake has been officially named by Met Éireann. The strongest gusts will mainly affect Ireland with lower impacts for the UK.

Winds will strengthen around southwest parts of the UK through this morning, particularly as a band of showers moves southeastwards across parts of Wales and southwest England.

Along the band of showers there is scope for some locally squally winds and so disruption to travel but the period of strongest winds will be short lived.

General Information on using Waterways Ireland inland navigations

Safety on the Water

All users of the navigations are strongly recommended to make themselves aware of safety on the water for whatever activity they are involved in and to read the advice offered by the various governing bodies and by:

The Dept. of Transport, Ireland: www.gov.ie/transport and The Maritime and Coastguard Agency, UK, The RNLI – Water Safety Ireland for information in terms of drowning prevention and water safety.

Registration of Vessels

All vessels using the Shannon Navigation, which includes the Shannon-Erne Waterways and the Erne System must be registered with Waterways Ireland. Only open undecked boats with an engine of 15 horsepower or less on the Shannon Navigation, and vessels of 10 horsepower or less on the Erne System, are exempt. Registration is free of charge.

Craft registration should be completed online at: https://www.waterwaysireland.org/online-services/craft-registration

Permits for use of the Grand and Royal Canals and the Barrow Navigation

All vessels using the Grand and Royal Canals and the Barrow Navigation must display appropriate valid Permit(s) i.e A Combined Mooring and Passage Permit (€126) and if not intending to move every five days, an Extended Mooring Permit (€152).

Permit applications should be completed online at: https://www.waterwaysireland.org/online-services/canal-permits

Passage on the Royal and Grand Canals – Dublin Area

For boat passage through the locks east of Lock 12 into / out of Dublin on either the Royal or Grand Canals, Masters are requested to contact the Waterways Ireland Eastern Regional Office (M-F 9.30am-4.30pm) on tel: +353(0)1 868 0148 or email [email protected] prior to making passage in order to plan the necessary lock-keeping assistance arrangements.

On the Grand Canal a minimum of two days notice prior to the planned passage should be given, masters should note that with the exception of pre-arranged events, a maximum of 2 boats per day will be taken through the locks, travelling either east or west.

Movements in or out of the city will be organised by prior arrangement to take place as a single movement in one day. Boaters will be facilitated to travel the system if their passage is considered to be safe by Waterways Ireland and they have the valid permit(s) for mooring and passage.

Newcomen Lifting Bridge

On the Royal Canal two weeks’ notice of bridge passage (Newcomen Lifting Bridge) is required for the pre-set lift date, and lock assistance will then also be arranged. A minimum of 2 boats is required for a bridge lift to go ahead.

Waterways Ireland Eastern Regional Office (Tel: +353(0)1 868 0148 or [email protected] ) is the point of contact for the bridge lift.

A maximum number of boats passing will be implemented to keep to the times given above for the planned lifts (16 for the Sat / Sun lifts & 8 for the weekday lifts). Priority will be given on a first come first served basis.

On day of lift, boaters and passengers must follow guidance from Waterways Ireland staff about sequence of passage under bridge & through Lock 1, and must remain within signed and designated areas.

Events Held on the Waterways

All organised events taking place on the waterways must have the prior approval of Waterways Ireland. This is a twelve week process and application forms must be accompanied with the appropriate insurance, signed indemnity and risk assessment. The application should be completed on the Waterways Ireland events page at :

https://www.waterwaysireland.org/online-services/event-approval

Time Limits on Mooring in Public Harbours

On the Shannon Navigation and the Shannon-Erne Waterway craft may berth in public harbours for five consecutive days or a total of seven days in any one month.

On the Erne System, revised Bye Laws state that: No master or owner shall permit a vessel, boat or any floating or sunken object to remain moored at or in the vicinity of any public mooring, including mooring at any other public mooring within 3 kilometres of that location, for more than 3 consecutive days and shall not moor at that same mooring or any other public mooring within 3 kilometres of that location within the following 3 consecutive days without prior permission by an authorised official.

Winter Mooring on the Shannon Navigation and Shannon Erne Waterway

Winter mooring may be availed of by owners during the period 1 Nov to 31 Mar by prior arrangement and payment of a charge of €63.50 per craft. Craft not availing of Winter Mooring must continue to comply with the “5 Day Rule”. Winter Mooring applications should be completed online at : https://www.waterwaysireland.org/online-services/winter-moorings-booking

Owners should be aware that electricity supply and water supply to public moorings is disconnected for the winter months. This is to protect against frost damage, to reduce running costs and to minimise maintenance requirements during the winter months.

Vessel owners are advised that advance purchasing of electricity on the power bollards leading up to the disconnection date should be minimal. Electricity credit existing on the bollards will not be recoverable after the winter decommissioning date. Both services will be reinstated prior to the commencement of the next boating season.

Smart Cards

Waterways Ireland smart cards are used to operate locks on the Shannon Erne Waterway, to access the service blocks, to use the pump-outs along the navigations, to avail of electrical power at Waterways Ireland jetties.

Berthing in Public Harbours

Masters are reminded of the following:

  • Equip their vessel with mooring lines of appropriate length and strength and only secure their craft to mooring bollards and cleats provided for this purpose.
  • Ensure the available berth is suitable to the length of your vessel, do not overhang the mooring especially on finger moorings on floating pontoon moorings.
  • Ensure mooring lines, electric cables and fresh water hoses do not create a trip hazard on public jetties for others users.
  • Carry sufficient fenders to prevent damage to your own vessel, other vessels and WI property.
  • Allow sufficient space between your vessel and the vessel ahead /astern (c.1m) for fire safety purposes and /or to recover somebody from the water.
  • Do not berth more than two vessels side by side and ensure there is safe access/egress at all times between vessels and onto the harbour itself.
  • Do not berth in such a way to prevent use of harbour safety ladders, slipways or pump-outs.
  • Do not allow the bow of your vessel to overhang the walkway of a floating mooring thus creating a hazard for others with an overhanging anchor or bow fendering.
  • Animals are not allowed to be loose or stray at any time.
  • Harbour and jetty infrastructure such as railings, power pedestals, fresh water taps, electric light poles, safety bollards, ladders etc are not designed for the purpose of mooring craft , they will not bear the strain of a vessel and will be damaged.
  • At Carrybridge on the Erne System, Masters of vessels are not permitted to use stern on mooring. Masters of vessels must use the mooring fingers for mooring of vessels and for embarkation / disembarkation from vessels.

Passenger Vessel Berths

Masters of vessels should not berth on passenger vessel berths where it is indicated that an arrival is imminent. Passenger vessels plying the navigations generally only occupy the berths to embark and disembark passengers and rarely remain on the berths for extended periods or overnight.

Lock Lead-in Jetties

Lead-in jetties adjacent to the upstream and downstream gates at lock chambers are solely for the purpose of craft waiting to use the lock and should not be used for long term berthing.

Vessel Wake

Vessel wake, that is, the wave generated by the passage of the boat through the water, can sometimes be large, powerful and destructive depending on the hull shape and engine power of the vessel. This wake can be detrimental to other users of the navigation when it strikes their craft or inundates the shoreline or riverbank. Masters are requested to frequently look behind and check the effect of their wake / wash particularly when passing moored vessels, on entering harbours and approaching jetties and to be aware of people pursuing other activities such as fishing on the riverbank.

Speed Restriction

A vessel or boat shall not be navigated on the Shannon Navigation at a speed in excess of 5 kph when within 200 metres of a bridge, quay, jetty or wharf, when in a harbour or canal or when passing within 100 metres of a moored vessel or boat.

Vessels navigating the Shannon-Erne Waterway should observe the general 5 kph speed limit which applies along the waterway. This is necessary in order to prevent damage to the banks caused by excessive wash from vessels.

Vessels navigating the Erne System should observe the statutory 5kt / 6mph / 10kph speed limit areas.

A craft on the Royal and Grand canals shall not be navigated at a speed in excess of 6km per hour.

A craft on the Barrow Navigation shall not be navigated at a speed in excess of 11km per hour except as necessary for safe navigation in conditions of fast flow.

Bank Erosion

Narrow sections of all the navigations are particularly prone to bank erosion due to the large wash generated by some craft. Masters are requested to be vigilant and to slow down to a speed sufficient to maintain steerage when they observe the wash of their craft inundating the river banks.

Unusual Waterborne Activity

Unusual waterborne vessels may be encountered from time to time, such as, hovercraft or amphibious aircraft / seaplanes. Masters of such craft are reminded to apply the normal “Rule of the Road” when they meet conventional craft on the water and to allow extra room to manoeuvre in the interest of safety.

Sailing Activity

Mariners will encounter large numbers of sailing dinghies from late June to August in the vicinity of Lough Derg, Lough Ree and Lower Lough Erne. Sailing courses are marked by yellow buoys to suit weather conditions on the day. Vessels should proceed at slow speed and with due caution and observe the rules of navigation when passing these fleets, as many of the participants are junior sailors under training.

Rowing

Mariners should expect to meet canoes and vessels under oars on any part of the navigations, but more so in the vicinity of Athlone, Carrick-on-Shannon, Coleraine, Enniskillen and Limerick. Masters are reminded to proceed at slow speed and especially to reduce their wash to a minimum when passing these craft as they can be easily upset and swamped due to their very low freeboard and always be prepared to give way in any given traffic situation.

Canoeing

Canoeing is an adventure sport and participants are strongly recommended to seek the advice of the sport’s governing bodies i.e Canoeing Ireland and the Canoe Association of Northern Ireland, before venturing onto the navigations.

Persons in charge of canoes are reminded of the inherent danger to these craft associated with operating close to weirs, sluice gates, locks and other infrastructure particularly when rivers are in flood and large volumes of water are moving through the navigations due to general flood conditions or very heavy localised precipitation e.g. turbulent and broken water, stopper waves. Shooting weirs is prohibited without prior permission of Waterways Ireland.

Canoeists should check with lockkeepers prior entering a lock to ensure passage is done in a safe manner. Portage is required at all unmanned locks.

Canoe Trail Network – "Blueways"

Masters of powered craft are reminded that a canoe trail network is being developed across all navigations and to expect more organised canoeing along these trails necessitating slow speed and minimum wash when encountering canoeists, rowing boats etc

Rockingham and Drummans Island Canals – Lough Key

It is expected that work on Rockingham and Drummans Island Canals on Lough Key will be completed in 2021. Access to these canals will be for non-powered craft only, eg canoes, kayaks, rowing boats.

Fast Powerboats and Personal Watercraft (Jet Skis)

Masters of Fast Powerboats (speed greater than 17kts) and Personal Watercraft (i.e.Jet Skis) are reminded of the inherent dangers associated with high speed on the water and especially in the confines of small bays and narrow sections of the navigations. Keeping a proper look-out, making early alterations to course and /or reducing speed will avoid conflict with slower vessels using the navigation. Personal Watercraft are not permitted to be used on the canals.

Towing Waterskiers, Wakeboarders, Doughnuts etc

Masters of vessels engaged in any of these activities are reminded of the manoeuvring constraints imposed upon their vessel by the tow and of the added responsibilities that they have to the person(s) being towed. These activities should be conducted in areas which are clear of conflicting traffic. It is highly recommended that a person additional to the master be carried to act as a “look-out” to keep the tow under observation at all times.

Prohibition on Swimming

Swimming in the navigable channel, particularly at bridges, is dangerous and is prohibited due to the risk of being run over by a vessel underway in the navigation.

Age Restrictions on operating of powered craft

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the minimum age for operating of powered craft. The Statutory Instrument contains the following requirements:

- The master or owner of a personal watercraft or a fast power craft shall take all reasonable steps to ensure that a person who has not attained the age of 16 years does not operate or control the craft

- The master or owner of a pleasure craft powered by an engine with a rating of more than 5 horse power or 3.7 kilowatts shall take all reasonable steps to ensure that a person who has not attained the age of 12 years does not operate or control the craft.

Lifejackets and Personal Flotation Devices (PFDs)

Lifejackets and PFD’s are the single most important items of personal protective equipment to be used on a vessel and should be worn especially when the vessel is being manoeuvred such as entering / departing a lock, anchoring, coming alongside or departing a jetty or quayside.

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the wearing of Personal Flotation Devices. The Statutory Instrument contains the following requirements:

- The master or owner of a pleasure craft (other than a personal watercraft) shall ensure, that there are, at all times on board the craft, sufficient suitable personal flotation devices for each person on board.

- A person on a pleasure craft (other than a personal watercraft) of less than 7 metres length overall shall wear a suitable personal flotation device while on board an open craft or while on the deck of decked craft, other than when the craft is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person who has not attained the age of 16 years complies with paragraph above.

- The master or owner of a pleasure craft (other than a personal watercraft), shall take all reasonable steps to ensure that a person who has not attained the age of 16 years wears a suitable personal flotation device while on board an open craft or while on the deck of a decked craft other than when it is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person wears a suitable personal flotation device, at all times while – (a) being towed by the craft, (b) on board a vessel or object of any kind which is being towed by the craft.

Firing Range Danger Area – Lough Ree

The attention of mariners is drawn to the Irish Defence Forces Firing Range situated in the vicinity of buoys No’s 2 and 3, on Lough Ree on the Shannon Navigation. This range is used regularly for live firing exercises, throughout the year, all boats and vessels should stay clear of the area marked with yellow buoys showing a yellow "X" topmark and displaying the word "Danger".

Shannon Navigation, Portumna Swing Bridge Tolls

No attempt should be made by Masters’ of vessels to pay the bridge toll while making way through the bridge opening. Payment will only be taken by the Collector from Masters when they are secured alongside the jetties north and south of the bridge.

Navigating from Killaloe to Limerick on the Shannon Navigation

The navigation from Killaloe to Limerick involves passage through Ardnacrusha locks, the associated headrace and tailrace and the Abbey River into Limerick City. Careful passage planning is required to undertake this voyage. Considerations include: lock passage at Ardnacrusha, water flow in the navigation, airdraft under bridges on Abbey River in Limerick, state of tide in Limerick

Users are advised to contact the ESB Ardnacrusha hydroelectric power station (00353 (0)87 9970131) 48 hours in advance of commencing their journey to book passage through the locks at Ardnacrusha. It is NOT advised to undertake a voyage if more than one turbine is operating (20MW), due to the increased velocity of flow in the navigation channel, which can be dangerous. To ascertain automatically in real time how many turbines are running, users can phone +353 (0)87 6477229.

For safety reasons the ESB has advised that only powered craft with a capacity in excess of 5 knots are allowed to enter Ardnacrusha Headrace and Tailrace Canals.

Passage through Sarsfield Lock should be booked on +353-87-7972998, on the day prior to travel and it should be noted also that transit is not possible two hours either side of low water.

A Hydrographic survey in 2020 of the navigation channel revealed that the approach from Shannon Bridge to Sarsfield Lock and the Dock area has silted up. Masters of vessels and water users are advised to navigate to the Lock from Shannon bridge on a rising tide one or two hours before High Tide.

Lower Bann Navigation

The attention of all users is drawn to the “Users Code for the Lower Bann”, in particular to that section covering “Flow in the River” outlining the dangers for users both on the banks and in the navigation, associated with high flow rates when the river is in spate. Canoeists should consult and carry a copy of the “Lower Bann Canoe Trail” guide issued by the Canoe Association of Northern Ireland. Users should also contact the DfI Rivers Coleraine, who is responsible for regulating the flow rates on the river, for advisory information on the flow rates to be expected on any given day.

DfI Rivers Coleraine. Tel: 0044 28 7034 2357 Email: [email protected]

Lower Bann Navigation – Newferry – No wake zone

A No Wake Zone exists on the Lower Bann Navigation at Newferry. Masters of vessels are requested to proceed at a slow speed and create no wake while passing the jetties and slipways at Newferry.

Overhead Power Lines (OHPL) and Air draft

All Masters must be aware of the dangers associated with overhead power lines, in particular sailing vessels and workboats with cranes or large air drafts. Voyage planning is a necessity in order to identify the location of overhead lines crossing the navigation.

Overhead power line heights on the River Shannon are maintained at 12.6metres (40 feet) from Normal Summer level for that section of navigation, masters of vessels with a large air draft should proceed with caution and make additional allowances when water levels are high.

If a vessel or its equipment comes into contact with an OHPL the operator should NOT attempt to move the vessel or equipment. The conductor may still be alive or re-energise automatically. Maintain a safe distance and prevent third parties from approaching due to risk of arcing. Contact the emergency services for assistance.

Anglers are also reminded that a minimum ground distance of 30 metres should be maintained from overhead power lines when using a rod and line.

Submarine Cables and Pipes

Masters of vessels are reminded not to anchor their vessels in the vicinity of submarine cables or pipes in case they foul their anchor or damage the cables or pipes. Look to the river banks for signage indicating their presence.

Water Levels - Precautions

Low Water Levels:

When water levels fall below normal summer levels masters should be aware of:

Navigation

To reduce the risk of grounding masters should navigate on or near the centreline of the channel, avoid short cutting in dog-legged channels and navigating too close to navigation markers.

Proceeding at a slow speed will also reduce “squat” effect i.e. where the vessel tends to sit lower in the water as a consequence of higher speed.

Slipways

Reduced slipway length available under the water surface and the possibility of launching trailers dropping off the end of the concrete apron.

More slipway surface susceptible to weed growth requiring care while engaged in launching boats, from slipping and sliding on the slope. Note also that launching vehicles may not be able to get sufficient traction on the slipway once the craft is launched to get up the incline.

Bank Erosion

Very dry riverbanks are more susceptible to erosion from vessel wash.

Lock Share

Maximising on the number of vessels in a lock will ensure that the total volume of water moving downstream is decreased. Lock cycles should be used for vessels travelling each way.

High Water Levels:

When water levels rise above normal summer level masters should be aware of:

Navigation

Navigation marks will have reduced height above the water level or may disappear underwater altogether making the navigable channel difficult to discern.

In narrow sections of the navigations water levels will tend to rise more quickly than in main streams and air draft at bridges will likewise be reduced.

There will also be increased flow rates particularly in the vicinity of navigation infrastructure such as bridges, weirs, locks etc where extra care in manoeuvring vessels will be required.

Harbours and Jetties

Due care is required in harbours and at slipways when levels are at or near the same level as the harbour walkways' as the edge will be difficult to discern especially in reduced light conditions. It is advised that Personal Flotation Devices be worn if tending to craft in a harbour in these conditions.

Slipways

Slipways should only be used for the purpose of launching and recovering of water craft or other objects from the water. Before using a slipway it should be examined to ensure that the surface has sufficient traction/grip for the intended purpose such as launching a craft from a trailer using a vehicle, that there is sufficient depth of water on the slipway to float the craft off the trailer before the concrete apron ends and that the wheels of the trailer do not drop off the edge of the slipway. That life-saving appliances are available in the vicinity, that the vehicle is roadworthy and capable of coping with the weight of the trailer and boat on the incline. It is recommended that slipway operations are conducted by two persons.

Caution to be Used in Reliance upon Aids to Navigation

The aids to navigation depicted on the navigation guides comprise a system of fixed and floating aids to navigation. Prudent mariners will not rely solely on any single aid to navigation, particularly a floating aid to navigation. With respect to buoys, the buoy symbol is used to indicate the approximate position of the buoy body and the ground tackle which secures it to the lake or river bed. The approximate position is used because of the practical limitations in positioning and maintaining buoys in precise geographical locations. These limitations include, but are not limited to, prevailing atmospheric and lake/river conditions, the slope of and the material making up the lake/river bed, the fact that the buoys are moored to varying lengths of chain, and the fact that the buoy body and/or ground tackle positions are not under continuous surveillance. Due to the forces of nature, the position of the buoy body can be expected to shift inside and outside the charted symbol.

Buoys and perches are also moved out of position or pulled over by those mariners who use them to moor up to instead of anchoring. To this end, mariners should always monitor their passage by relating buoy/perch positions with the published navigation guide. Furthermore, a vessel attempting to pass close by always risks collision with a yawing buoy or with the obstruction that the buoy or beacon/perch marks.

Masters of Vessels are requested to use the most up to date Navigation guides when navigating on the Inland Waterways.
