#Fishing - The Marine Institute and Bord Iascaigh Mhara (BIM) convened an information meeting on the Aran Grounds Nephrops fishery and recent gear trials at the institute's headquarters in Oranmore this week.

The meeting on Tuesday 24 February was attended by more than 30 active skippers together with representatives from the IFPO, IS&WPO, IS&EPO and the KFO.

Marine Institute port-based and BIM gear technology personnel, as well as a Department of Agriculture, Food and Marine official were also in attendance.

Dr Paul Connolly, director of fisheries and ecosystem services at the Marine Institute, opened the meeting by saying that Nephrops (better known as Dublin Bay prawns or langoustines) are "a key resource for Irish fishermen, as over the last five years the value of the landings at first sale has doubled to almost €50m in 2014. Sustaining the stocks and the quota is a key management priority for the industry and the department."

He also noted that it was positive to see scientists and so many active fishermen discussing issues together.

The group heard presentations on the methodology and results of Marine Institute Nephrops Underwater Television Surveys (UWTV) on the Aran Grounds and other areas by Jennifer Doyle of the Marine Institute.

The latest ICES assessments and management advice for Nephrops on the Aran Grounds was also presented by Dr Colm Lordan from the Marine Institute, who chaired the discussions by the group.

Dr Lordan highlighted that "the assessments indicate that the stock size has declined to the lowest in the time series in 2014.

"Although fishing effort in terms of number of boat and days fished on the Aran Grounds shows no long-term trend since 1995, there has been an increase in both fishing power and efficiency with the increased uptake of quad rigs in the fishery".

According to Dr Lordan, a combination of high landings and reduced recruitment has resulted in harvest rates in 2012-2013 being twice that recommended by ICES.

He further advocated "national measures to reduce catches and effort in the short term in advance of the 2015 UWTV survey were required. This would demonstrate responsible management and give the best chance for increased stock size in June."

In response to this, Francis O'Donnell of the IFPO proposed that effort on vessels less than 20m would be limited to less than 20 days and effort for vessels larger than 20m would be limited to less than 10 days for the months of April and May. This was going to severely have an impact on some of his members, he said.

David Kirwan of the IS&EPO suggested that effort for all vessels be limited to less than 40 days for the three-month period April to June.

These proposals will be investigated by the Marine Institute to assess if they would be likely to deliver significant catch and effort reductions.

#MarineScience - The Atlantic Ocean: Our Unknown Treasure was on the agenda at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Jose, California on Saturday 14 February.

Marine Institute chief executive Dr Peter Heffernan joined European Commission officials and leading scientists from the USA, Europe and Canada to discuss how to explore the largely unknown Atlantic Ocean; how new technologies can help us to challenge our understanding of the planet; and how new observation and visualisation tools can improve what we know about the seabed and inform science to help shape future marine policy.

The event built on the Galway Statement on Atlantic Ocean Research Co-operation signed at the Marine Institute in May 2013 by representatives from the EU, Canada and the US, launching an Atlantic Ocean Research Alliance.

Its goals are to better understand the Atlantic and the Arctic, to study the interplay between them, particularly relating to climate change, and to promote sustainable management of their resources.

Speaking about the event, Dr Heffernan said: "It's an exciting time, as all sides - European, US and Canadian - have shown engagement, planning and commitment to driving the Atlantic Ocean Research Alliance forward and preparing joint actions.

"There are very real global challenges to be tackled, and there is strong momentum now to create significant benefits such as better ecosystem assessments and forecasts and deeper understandings of vulnerabilities and risks.

"These transatlantic collaborations will also help to generate new tools to increase resilience and adaptation and to conserve our rich biodiversity. We also really need to foster public understanding of how ocean science and observation will address pressing issues for citizens and for the environment."

Dr Heffernan concluded: "The AAAS meeting gave an opportunity to see some of the collaborations that are undertaken in the Atlantic Ocean and discuss challenges for future research, technological developments, mapping and imaging as well as research co-operation across the Atlantic."

#MarineScience - Ciaran O’Donnell, a specialist in fisheries acoustic research with Fisheries Ecosystem Advisory services at the Marine Institute, has just begun a PhD research project that will link fisheries and seabed mapping acoustic technologies.

By using both technologies, he aims to learn more about how fish behave during acoustic surveys and therefore increase the precision of fish stock assessments.

O’Donnell’s research will focus on pelagic species – fish that swim in the water column – to see if there is avoidance behaviour during acoustic surveys and also to look at schooling behaviour and preferred habitat.

He’ll use the state-of-the-art multibeam echosounder system that has just been installed on the RV Celtic Explorer to look beyond the data normally captured during acoustic fisheries surveys to see if some or any of the fish being targeted by the survey are moving away from the research vessel as it passes overhead them.

“I’m really looking forward to the sea trials of the new multibeam next week (16-24 February) when we’ll get a chance to use the most advanced seabed mapping technology alongside acoustic fisheries technology. We should be able to see a much broader picture than before," said O'Donnell, a chief scientist on annual surveys for blue whiting, Celtic Sea herring and boarfish.

“Acoustic surveys are very targeted and focussed and this will allow us to capture new information about what the fish are doing beyond the target of the downward-looking fisheries echosounder. It will be like getting enhanced peripheral vision of the sea around the ship.

“We’ll be able to see if fish are moving away from the research vessel and out of the survey path and therefore will potentially enhance the precision of our current survey methods.”

The project will bring together technology and data from fisheries and seabed mapping and O’Donnell will work closely with the INFOMAR team and the advanced mapping services at the Marine Institute.

The research project, originally designed by the INFOMAR team, brings together a number of experienced researchers including Dr Chris McGonigle and Dr Rory Quinn of the University of Ulster, Dr Fabio Sacchetti of INFOMAR and the Marine Institute, and Dr David Reid of the Marine Institute and UCC.

#MarineScience - The marine research vessel Celtic Explorer is back in the water with a new suite of hydrographic and geophysical sonar systems.

According to the Marine Institute, the new instruments were installed during an extensive refit in the A&P yard in Falmouth, which began on 29 December under the supervision of P&O Maritime (Ireland) Ltd.

The main work carried out during the refit was the installation of state-of-the-art sonar systems for bathymetric mapping in deep and shallow waters, and the installation of a deepwater sub-bottom profiler.

Adjustments were also made to the hull to fit the Kongsberg EM302 multibeam system and an IXSEA Echoes sub-bottom profiler.

These systems will enhance the seabed mapping capabilities of the Celtic Explorer, with the EM302 echo sounder designed to perform mapping with high resolution and accuracy to depths of 6km. The sub-bottom profiler can operate at the same depths to examine and profile surface bedrock layers and sediments.

The vessel's drop keel has been fitted with an EM2040 multibeam system – the same as that fitted to sister vessel the Celtic Voyager last year – to carry out high resolution seabed mapping in shallower waters. The vessel's positioning and motion reference systems were also upgraded to the highest standard to allow the vessel to operate the new equipment to the required accuracy.

The two-and-a-half-yearly refit included major mechanical work such as the removal of the rudder for inspection and repair and overhaul of the stern thruster. The entire vessel was painted; cabins, laboratories and common areas were refitted; and minor repairs carried out as well as an overhaul of essential systems.

The Celtic Explorer will complete a survey in the North Sea and Baltic Sea before beginning sea trials of the new equipment in Irish waters in February. The capability of the new equipment will be tested in the deep waters off Ireland's West coast under the supervision of scientists from the Marine Institute's Advanced Mapping Services (AMS) team.

Once the new systems have been calibrated and tested, they will be used extensively this year, including on fisheries acoustic surveys where their water column capability will be used to study the aggregation morphology and vessel avoidance behaviour of pelagic fish species, as part of a new PhD study.

The new systems will also be used to map the deep Atlantic seafloor during passage to and from Canada in April-May this year, and will be key during two deepwater ROV surveys this year, one led by University College Cork studying cold water coral reefs, and another led by University College Dublin studying deepwater thermal vent sites on the Mid-Atlantic Ridge.

The Celtic Explorer will deliver an intensive programme of activities in 2015 with a packed schedule to 17 December.

Beyond 2015, the systems will be used extensively to map the Celtic Sea, which will provide valuable data for the sustainable development of Ireland's fisheries as well as allowing Irish scientists the opportunity to play a pivotal role in future research opportunities in the deeper waters of the Atlantic Ocean.

#MarineWildlife - The mystery of where Ireland's humpback whales to go give birth remains – but two whales have been tracked between the Irish coast and feeding grounds in the Arctic for the first time.

That's the big news from a new research paper in the Journal of the Marine Biological Association of the United Kingdom, a collaborative effort between the Irish Whale and Dolphin Group (IWDG) and marine science colleagues in the United States, Iceland, Norway and the Netherlands.

According to co-author Dr Conor Ryan, the study reports on a comparison of the 28 humpback whales that have been photo IDed in Irish waters with a catalogue of over 8,000 such whales throughout the North Atlantic.

Ireland's "main stomping ground for humpbacks" was also examined in the paper, with a strong seasonal trend showing the whales appearing off the Kerry coast each summer – as tourists on the Wild Atlantic Way are becoming well aware.

IrishCentral reports on the latest BBC film shoot to capture the majestic marine mammals in their natural environment, before they move on to West Cork in autumn and further east to Waterford and Wexford as winter progresses – matching the movements of spawning sprat and herring shoals.

The IWDG website has much more on the story HERE.

#MarineScience - SmartBay Ireland has entered into a transatlantic collaboration agreement with the Fisheries and Marine Institute of Memorial University of Newfoundland in St John's, Newfoundland and Labrador, Canada, Dublin City University and the Marine Institute.

The Memorandum of Understanding was signed at a reception hosted by the Canadian Embassy during a recent Canadian trade mission to Ireland. Welcoming the agreement, Dr Peter Heffernan, CEO of the Marine Institute, said: "This is a tangible example of the type of transatlantic collaboration envisaged in the Galway Statement.

"I am especially pleased to build on the strong partnerships established with our colleagues in Newfoundland and to see the exciting collaborative opportunities in sensor technology test and demonstration for our linked SmartBay initiatives."

The agreement is designed to further consolidate and develop the partnership that exists between the marine institutes of Newfoundland and Labrador and Ireland and the SmartBay infrastructures.

Glenn Blackwood, vice-president of Memorial University, said: "Since the establishment of our marine institute, we have focused on building meaningful relationships with industry partners. This MOU solidifies our commitment to further strengthen ongoing links between SmartBay Newfoundland and Labrador and SmartBay Ireland and allows for increased collaboration on the work that both jurisdictions are conducting in the ocean industry."

The key aims of the agreement are the sharing of assets, capacity and capability in a joint mission to provide access by scientists, innovators and entrepreneurs to both SmartBay test and validation infrastructures currently deployed in the North Atlantic.

Dr Fiona Regan, director of the Marine and Environmental Sensing Technology Hub (MESTECH) and SmartBay Ireland principal investigator, added: "This exciting collaboration will enable the establishment of joint projects in the area of ocean observation with our academic and industry partners from Ireland and Canada, sharing expertise and infrastructure."

These objectives will be achieved through a range of activities including: joint industry and academic research projects; outreach and education programmes; and the identification of opportunities to leverage funding for joint research projects and the expansion of collaborative arrangements to include other jurisdictions bordering the North Atlantic.

John Breslin, general manager of SmartBay Ireland, said: "We are delighted to be working with our Canadian partners to utilise the infrastructure and expertise within both SmartBay facilities to identify and develop sensor-driven decision support tools to address specific industry needs within the oil and gas, aquaculture and telecommunications sectors."

This agreement is based on a common vision and cultural appreciation of the societal and economic value of the ocean and is another step toward the utilisation of the jurisdictions' joint facilities and expertise to deliver projects of scientific and economic benefit.

Ron Newhook, director of the Marine Institute of Newfoundland and Labrador's Office of Research and Development and Randy Gillespie, director of the institute's Centre for Applied Ocean Technology were part of the recent Newfoundland and Labrador trade mission to Ireland and attended the MOU signing.

"Capturing the spirit of the Galway Declaration, this new MOU renews and strengthens transatlantic collaborations between industry, governments, academia and NGOs," said Newhook.

"Together, SmartBay Ireland and the Marine Institute's Centre for Applied Ocean Technology, which currently operates SmartBay Newfoundland and SmartAtlantic, will lead the way in the development and implementation of a sustainable observatory which will provide information to support a safe and sustainable ocean industry in the broad North Atlantic."

#MarineWildlife - The secrets to a longer lifespan could be hiding in the genes of the bowhead whale, according to a new scientific study.

Silicon Republic has news of the paper involving scientists from Dublin City University that explores the genome of the Arctic whale species, thought to be among the longest living animals on earth.

As mammals like humans, the "molecular mechanisms underlying their exceptional longevity and resistance to age-related disease are of particular interest for human health," says Dr Mary O'Connell, a contributor to the study.

Key among the findings were a set of genes distinct from the closely related but shorter-lived minke whale that are associated with repairing DNA and resistance to cancer.

The next step in this research is to see if these genes can impart resistance to ageing when adapted to different models, which could show their potential for anti-cancer therapy in humans.

Silicon Republic has more on the story HERE.

#MarineWildlife - 2014 brought us some offbeat marine wildlife stories on Afloat.ie, from a sea lion leaping onto a speedboat to nab himself a fish, to a French 'bad boy' dolphin's tour of Ireland's west coast.

We also learned that whale poo could be the key to combating climate change, and who can forget the giant 'shrimp' pulled from Florida's waters, or the surfing pig making waves in Hawaii?

But there some other weird and wonderful discoveries that we missed. Take for instance the strange mushroom-shaped 'living fossils' found in deep water off Australia over the summer, according to Discovery News.

Two species of the barnacle-like organisms were discovered by researchers from the University of Copenhagen living more than 3,000 feet below sea level, and "represent an early branch on the tree of life".

More recently, culture blog Boing Boing shares a video of conjoined Pacific gray whale calves that washed ashore in Mexico, a popular birthing ground for the species safe from their main predator, the orca.

Still, as exiting as these events are, the day-to-day work for most marine science experts is more down to earth but no less important, as marine biologist Monica McLaird gives an account of her average day's work to Lisburn Today.

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.

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.
