The Marine Institute’s marine glider has been deployed in the North Atlantic as part of a deep ocean marine science research project.

Laochra na Mara can reach depths of 1,000m and collects oceanographic data on conductivity, temperature, depth, fluorescence, turbidity and dissolved oxygen.

The glider was deployed from the RV Águas Vivas as part of the fifth project meeting for the Innovation in the Framework of the Atlantic Deep Ocean (iFADO) project recently held in The Azores, Portugal.

Prior to deployment, the glider was exhibited to the public at the Horta Maritime Terminal where local school students met iFADO team members and viewed several videos about glider operations and missions.

The school students also wrote messages on the glider before it was launched.

“Equipped with a wide variety of sensors, the glider can gather information about ocean temperature, salinity and currents, and transmits this information to shore via satellite,” Thomas Dabrowski of the Marine Institute said.

“Gliders are able to provide real-time data, and provide a better assessment and understanding of our ocean environment.”

Gliders are programmed to surface at designated times and transmit the data collected while at the same time downloading new mission instructions. This two-way communication allows gliders to continually gather information about the most important and diverse regions of our ocean basins 24 hours a day.

Similar to a glider from the United States that was found off Baltimore in 2017, the Slocum glider was recently recovered in the North Atlantic Ocean after 15 days at sea — during which it covered over 250km and performed over 40 deep dives.

The fifth iFADO project meeting gathered 50 participants and partner leads to hear the latest results and discuss future co-operation and follow-up action.

The iFADO project aims to create marine services at regional and sub-regional scale using the EU’s Atlantic waters as a case study. It combines traditional monitoring with cost-effective state-of-the-art technologies such as remote sensing, numerical modelling and emerging observation platforms such as gliders and oceanic buoys.

The Marine Institute is one of 20 partners from Ireland, the UK, France, Portugal and Spain involved in the iFADO project. The project has received funding from the European Union’s Interreg Atlantic Area Programme.

#Fishing - Sean Kyne TD, Minister with responsibility for the inland fisheries sector, today (Thursday 21 June) welcomed the positive outcome from the international discussions at the North Atlantic Salmon Conservation Organisation (NASCO) annual meeting in Portland, Maine, USA.

“Our departmental officials and those of Inland Fisheries Ireland represented Ireland at the negotiations as part of the EU delegation,” Minister Kyne said. “They joined delegates from the EU, USA, Canada, Norway, the Russian Federation, Greenland and the Faroes.

“The outcome of the week-long discussions is that, for the period 2019-2022, no harvest fishery will take place off the Faroe Islands and the restrictions on the fishery off West Greenland have been strengthened.

“I am pleased that these two important regulatory measures were agreed in a spirit of international c-ooperation.”

Minister Kyne emphasised the importance of these measures for Irish salmon migrating to distant feeding grounds before returning to their natal rivers in adulthood to spawn.

“The migratory stock complex travelling through Faroese waters comprises a majority component of European river stocks, including those from Ireland, and the measure to have no commercial fishing in these waters is important for these vulnerable stocks,” he said.

“I am particularly pleased that the discussions on the Faroes area were chaired by Ireland, on behalf of the EU.”

The majority component of the stock complex migrating to Greenlandic waters originates from the North American continent, and the restriction on fishing in this area assists these stocks as well as the smaller European component.

The agreed level of potential catch, for the internal use fishery in Greenland, is reduced by some 33% over the quota set in each of the last three years. Agreement was also reached on increased monitoring and control of the fishery.

The NASCO meeting also considered the factors that affect the marine survival of Atlantic salmon, with scientists, including those from IFI, engaged in cutting edge work to identify and address those causes.

Determining why salmon are dying at sea before they can come back to their natal rivers to spawn is a key research priority.

A new innovative approach to oceanic long range acoustic monitoring, ‘ROAM’ (RAFOS Ocean Acoustic Monitoring), will allow salmon to be tracked through the marine environment. The approach is intended to overcome many of the significant challenges associated with tracking Atlantic salmon throughout their extensive marine migration.

Minister Kyne concluded that the measures taken in Ireland, over a decade ago, to protect migratory salmon stocks have pointed the way internationally and the latest agreements at NASCO demonstrate restraints on exploiting Irish and other stocks as they migrate outside our waters.

#Unmanned - A miniature unmanned sailing boat has been reported off the Kerry coast after nearly three years in the North Atlantic.

The boat, named West, is part of the Educational Passages project by the Middle School of Westbrook in Maine, USA and is one of five boats the Sebago School Alliance sent out in the autumn and winter of 2013-14.

West was launched off Georges Bank along with one other boat by Bro Cote, a lobsterman out of Hyannis, Massachusetts. Several others were launched about the same time off the Mid-East coast of the United States and off the Canary Islands for the marine science project.

“We had hoped the boat would make the complete circle of the Atlantic Ocean. It has and then some,” say the project organsiers about West, which has been spotted 32 nautical miles from the Kerry coastline.

West could arrive in the Kerry area over the next few days or, depending upon weather conditions, may go further northwards towards the Galway coast.

Previously West made landfall in November 2014 when it crashed on rocks in rough seas off Portugal, where it was recovered by local authorities and repaired with the help of local companies and relaunched from Lisbon in June last year.



Four months later, it was recovered entering the Mediterranean, refurbished again and put on a cargo ship to Madeira and relaunched from there on 28 January this year.

The project co-ordinators have asked for assistance to help rescue the boat when it arrives in the coming days

“It would be great if the boat could be recovered at sea or shortly after landing to avoid damage."

#SeabedMapping - The Atlantic Ocean Research Alliance's fifth transatlantic seabed mapping survey launched last Friday 22 July from eastern Canada.

Sailing on the Canadian Coast Guard Ship Louis S St-Laurent, the team will map the seafloor across the North Atlantic between Halifax in Nova Scotia and Tromso in Norway till next Tuesday 2 August.

The marine science team led by Paola Travaglini of Fisheries and Oceans Canada's Hydrographic Service are using state-of-the-art deep-water multibeam sonar technology to survey the seabed and study the physical characteristics of the seafloor, as well as other oceanographic data such as temperature and salinity, to better understand little-known areas of the North Atlantic and build on the work done last summer.

These surveys support the Galway Statement on Atlantic Ocean Co-operation, the goals of which are to join resources of its three signatories to better understand the North Atlantic, to promote sustainable management of its resources, and to promote citizens' understanding of the Atlantic through ocean literacy.

Participants in the survey include Fisheries and Oceans Canada's Hydrographic Service, the University of New Hampshire's Center for Coastal and Ocean Mapping Joint Hydrographic Center, and the Fisheries and Marine Institute of Memorial University of Newfoundland.

Students and early-career scientists representing Canada and the United States sailing on board the CCGS Louis S St-Laurent are writing daily blog posts to chronicle the mission. The team comprises:

  • David Thornhill, Hydrographer, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Danielle Roche, Marine Institute of Memorial University of Newfoundland
  • Darren Hiltz, Hydrographer, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Elizabeth Weindren, University of New Hampshire's Center for Coastal and Ocean Mapping Joint Hydrographic Center Fisheries
  • Chris Hemmingway, National Director of UNCLOS, Fisheries and Oceans Canada Canadian Hydrographer Service
  • David Levy, Electrical Technician, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Paola Travaglini, Hydrographer–In–Charge, Fisheries and Oceans Canada Canadian Hydrographer Service

Seabed mapping was one of the ocean research priorities and challenged discussed by the Marine Institute's CEO Dr Peter Heffernan with other heads of European marine science institutes in Ostend earlier this month, which followed a previous consultation that identified such mapping as crucial for managing human activities in our seas.

#PublicLecture - 'The Little Ice Age and the North Atlantic Fish Revolution' is the title of a public lecture delivered by Prof Poul Holm and Dr Francis Ludlow of Trinity College Dublin at lunchtime this Wednesday 13 April at the Marine Institute headquarters in Oranmore, Co Galway.

Holm is Professor of Environmental History at the School of Histories and Humanities in TCD. In 2015 he was awarded an Advanced Grant of €2.5 million by the European Research Council. In the next five years he and his team will explore the North Atlantic 'fish revolution' circa 1400-1700 AD.

In 1497, John Cabot returned to Bristol from a voyage across the North Atlantic. He told of waters so thick with fish that they could be lifted straight on board in baskets. Within a few years of this journey, fishermen from all over Western Europe made the journey across. This was the beginning of the 'fish revolution' of the early-modern world.

The fish revolution was one of the first examples of the disrupting effects of globalisation and climate change. Fish was a high-priced, limited resource in the Late Middle Ages. The Grand Banks fishery offered abundant high-quality low-priced catches to the European market. At the same time climate worsened as the Little Ice Age drove down sea temperatures and changed marine ecosystems.

The consequences were dire for fishermen along the coasts from the Irish Sea right up to northern Norway. As they caught less cod locally at higher prices, the fishermen had the choice of migrating across the ocean or give up fishing. Many fishing settlements were deserted as inhabitants took to the road to seek casual work in agriculture or towns.

Kings and high politics were similarly affected by the fish revolution. The new resource held strategic importance for all major western European powers, such as Spain, Britain and France. North Atlantic warfare was about fish as well as about gold.

In recent years we have all been affected by the impact of global change. We want to know if we can untangle the drivers of prices and temperatures to explain the causes of the fish revolution, and we want to know how people understood and responded to the challenges of globalisation and climate change. The lecture posits that perhaps the fish revolution of the Middle Ages is a distant mirror for today.

All are welcome to the event at the Marine Institute Auditorium this Wednesday at 12 noon.

#MarineWildlife - The Guardian reports that fishing is expected to be banned near Rockall after the recent discovery of a rare ocean floor gas vent and new species of shellfish.

The 'cold seep' methane vent found by Scotland-based marine scientists last year is only the third of its kind to be found in this region of the Atlantic Ocean - and apparently has a 'chemosynthetic' relationship with two species of deep-water clam, and the polychaete worms they contain, that are new to science.

Also found was a frilled shark, described as a 'living fossil' for existing as a species for at least 90 million years. Such sharks are seldom seen north of the tropics.

In the wake of these findings, the International Convention on the Exploration of the Seas has recommended a ban on fishing activity at the site and its surrounds.

Rockall - which adventurer Nick Hancock is attempting to occupy for a world record attempt - is a tiny rocky islet north-east of Donegal, almost halfway between Ireland and Iceland in the North Atlantic. It has long been the subject of territorial dispute, with Ireland, the UK, Iceland and Denmark all staking a claim.

The Guardian has much more on the story HERE.

#Fishing - Drogheda is hosting the 30th annual meeting of the North Atlantic Salmon Conservation Organisation (NASCO) this week till Friday 7 June.

The prestigious fisheries conference will take place in the Westcourt Hotel and will be attended by delegates from Canada, Denmark (in respect of the Faroe Islands and Greenland), the European Union (representing its 27 member states), Norway, Russia and the USA.

Welcoming the conference to Drogheda on Tuesday 4 June, Minister Fergus O’Dowd said it "will continue the key work of NASCO, using the best scientific information, and international co-operation to conserve and manage Atlantic salmon populations.

"I wish the many delegates a friendly and intellectually stimulating stay in Drogheda where the meeting programme will no doubt provide insights and an outstanding platform for dynamic networking to ensure the continued conservation of our precious salmon stocks."

Based in Edinburgh, NASCO is an international organisation established by an intergovernmental convention in 1984. Its main function is to conserve, restore, enhance and rationally manage Atlantic salmon through international cooperation taking account of the best available scientific information.

NASCO is the only intergovernmental organisation with this mandate, which it implements through international consultation, negotiation and co-operation.

Ireland is at the forefront of salmon conservation internationally, according to Inland Fisheries Ireland, which adds that Irish participants at the conference include a Government delegation of managers and scientists and representatives of a number of Irish-based NGOs, including Salmon Watch Ireland.

The cross-border Loughs Agency, which has responsibility for salmon conservation and protection Foyle and Carlingford Loughs, will also be represented as part of the Irish delegation.

#TITANIC - The Titanic memorial cruise was yesterday forced to turn back just 100 miles from the southwest coast of Ireland after a passenger fell ill, BBC News reports.

The Irish Coast Guard rescue helicopter at Shannon was dispached to the MS Balmoral to retrieve BBC cameraman Tim Rex, 56, who was struck by a non-life threatening heart condition, according to the Irish Independent.

Rex, who was covering the memorial sailing for the BBC, was treated by ship's doctors before being airlifted to hospital as a precaution.

The emergency happened just hours after the ship departed Cobh, the last port of call of the ill-fated Titanic before it sank in the North Atlantic on 14 April 1912.

A spokesperson for Titanic Memorial Cruises confirmed that despite the delay, the ship is still on schedule and is expected to arrive at the Titanic wreck site as planned on Saturday.

#SURFING - Northern Irish surf pro Al Mennie will be taking on a different challenge later this month, when he sets out to paddle a surfboard from the Giant's Causeway to Scotland in the name of charity.

"It will be the northernmost crossing of its type in the world," says Mennie of the 25-mile route from Antrim to the Scottish island of Islay.

"I will have to deal with freezing cold temperatures, large open ocean swell, potentially high winds and the deadly currents around a well known navigational hazard of a North Atlantic island."

Mennie will be on his own except for a support boat carrying food and water. He will be wearing a 6mm wetsuit and crossing the most dangerous stretch of water around the Irish coastline, "known for its extremely deadly currents as the Irish Sea tides drain between Rathlin Island and Northern Ireland".

The NI surfer is embarking on the challenge in aid of Northern Ireland Chest Heart and Stroke, which is a charity close to his own heart.

"My dad died suddenly of a heart attack aged 50 and I know lots of people who have also lost loved ones to heart problems too," he says, "so I really want to help make a difference by raising money for this charity."

For more details or to make a donation, visit the charity page at Al Mennie's website HERE.

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.
