Scuba Divers have found a fully intact World War I U-Boat on the seabed just outside Cork harbour, some 93 years after it sank writes Timmy Carey.

During the First World War the menace provided by German U-Boats would prove deadly to the Allies and were responsible for sinking millions of tons of shipping; indeed German U-Boats almost changed the course of the war. Most allied ships sunk by U-boats were sunk by either torpedo, deck gunfire or explosives placed aboard the ship by U-boat crew. A smaller number of ships were also sunk by mine laying U-boats; one of these being UC42. On the 10th of September of 1917 UC42 was laying her deadly cargo of mines at the entrance to Cork harbour when a terrific explosion occurred which resulted in a grim death for all 27 German Submariners aboard.

As the submarine sank to the seabed the German submariners were trapped inside UC42, which would soon become their metal tomb.

On November  2nd of that year, hardhat divers from the Haulbowline dockyard dived the area and positively identified the U-boat as UC42, noting the stern damage to the submarine and the presence of the bodies of some of the German submariners. During 1918 the submarine was dived by Haulbowline and American divers in an effort to disarm all the mines and torpedoes still aboard, with USS Melville taking three of the mines. It was widely believed that in July 1919 divers using explosives from HMS Vernon torpedo school had destroyed the submarine with the remains being dispersed on the seabed by wire sweeps.

With the advent of scuba diving many divers have since searched for the scattered remains of UC42 around Cork harbour with no luck until a recent dive by two local divers Ian Kelleher and Niall O Regan descended a shot line to see the menacing sight of the hull of a German U-boat emerge from the shadows. Both divers were very surprised and ecstatic to find a fully intact World War I U-Boat in 27 meters of water just outside Cork harbour in good condition with little obvious explosive damage from the British naval dive team.

A local dive team of five divers had spent the previous 12 months carrying out a careful methodical search of the greater harbour area determined to find the remains of the submarine; their hard labours finally paying dividends when Niall and Ian identified the presence of the submarine. The dive team consisted of Ian Kelleher, Niall O Regan, Philip Johnston,  Eoin Mc Garry and Timmy Carey.

Over the past few weeks the divers have carefully and methodically videoed and photographed the Submarine and taken various measurements to record the wrecks' condition. Over a number of dives the dive team carefully cleaned the growth from the propeller and after some methodical cleaning found the U-Boats number UC42 stamped into it; positively identifying the submarine.

As the submarine is a war grave and contains the remains of so many young German submariners the dive team also laid a plaque of remembrance, which was erected near the submarines propellers; to act as a memorial to the German submariners forever entombed in UC42. The plaque was kindly donated to the dive team by John O' Mahony of Complete Signs.

Diving Asgard II

In September 2008 an iconic part of maritime Ireland silently and tacitly slipped beneath the surface of the Bay of Biscay near the idyllic island of Belle Isle writes Timmy Carey.

Asgard II was on a journey from Falmouth to La Rochelle for routine maintenance when it would succumb to its fate of a watery grave, thankfully captain Colm Newport was able to safely abandon the ship with the entire crew of 25.

Since 1981 Asgard II a beautiful brigantine designed by Jack Tyrell and built in Arklow had served the Irish nation with distinction all over the globe, providing sail training for over 10,000 people; the image of the bright green hull and white sails becoming synonymous with Irish sailing.

In addition to such a proud history, Asgard II also carried on the name and traditions of Asgard; which played such a pivotal role in Irish history and in the foundation of the state. In Norse religion Asgard was the home of the Norse gods and it is fitting that a vessel with such an auspicious name would later be called "the harbinger of Irish freedom" by the President of Ireland Eamonn De Valera.

Asgard was built in 1905 in larvik and was a wedding gift from Dr and Mrs Hamilton Osgood of Boston to their daughter Mary and her husband Erskine Childers (the father of the future president of Ireland). In a magnificent feat of seamanship (which was reminiscent of his famous novel the riddle of the sands) Erskine Childers in the company of his wife and others expertly collected arms from Hamburg and landed them in Howth on the 26th of July 1914 for the Irish volunteers. In one of the great ironies of Anglo-Irish history Erskine Childers a decorated British war veteran would become an avowed Irish republican and would play a crucial role in the struggle for independence as minister for propaganda (being very highly thought of by both Eamonn De Valera and Michael Collins); before being executed in the Irish civil war.

In 1961 the Irish government purchased the vessel for sail training and in 1968 Coiste and Asgard was founded and was assigned responsibility for the vessel. With the launch of Asgard II, the original Asgard was transferred to the national museum where it has been expertly restored to its original glory and will in the future be available for general viewing.

With such a rich maritime heritage and being so deeply engrossed in Irish history popular view in late 2008 was that the Irish government would salvage Asgard II as a symbol of Irish pride; alas it would later be decided by the Irish government to abandon Asgard II with the uniquely Irish bowsprit of Grainne Uaile condemned to a permanent watery grave on foreign shores.

As with many diving expeditions, they often begin with a simple conversation and one late night a phone call from Eoin McGarry would begin with "what do you think of diving the Asgard II next year". Soon the idea generated its own momentum and a small team of Irish trimix divers (all of whom are CFT members) was assembled and preliminary plans were made for July 2010.

Despite the fact that no permission was necessary to dive the vessel under Irish or French law, it was decided to notify the Irish government of dive teams intentions to video the wreck and recover some of the artefacts for the Irish people. On contacting Coiste an Asgard the reaction of the board was very negative indicating that the artefacts were of little value and that due to the depth involved they were not in favour of any dives taking place.

A little disillusioned it was decided to make representations directly to the Minister for Defence and soon a government TD with a real interest in Irish history discussed the idea with the Minister for Defence Willie O Dea.

The ships name looming out from the darkness

In early February the dive team would receive a personal letter from the minister indicating that "enquiries are being made into the matter and I will write to you again shortly". In addition a TD had also confirmed to the dive team that the minister had indicated that he thought it was a great idea and wished the dive team well. Unfortunately within a very short time period the minister had to resign and the dive team received no further correspondence.

With the Irish government engrossed in an economic recession of epic proportions, the dive team decided to proceed before the ships artefacts were removed by foreign dive teams and lost to the state forever.

With time ticking by the final team of Eoin Mc Garry as expedition organiser, Brendan Flanagan of Longford Sub Aqua club, Phil Murphy and Frank McKenna both of Kilkenny Sub Aqua and myself were assembled as the bottom divers. With an emphasis on keeping the costs down as the divers would be financing the trip, the decision would eventually be made to have one cover diver to help the divers kit up and look after all the surface logistics; this would also allow all the dive team travel together in the one vehicle and reduce the travel costs. Being a qualified mixed diver as well as native of Brittany; Stephane Portrait of Blackwater Sub Aqua Club would become an essential member of the dive team without whom the trip could not have been successful.

Over the coming months Stephane and Eoin would work tirelessly on the logistics, which would be vastly more onerous and detailed than an expedition to the Lusitania. As well as the small issues of organising ferries, accommodation, a dive centre and a dive boat; the dive team would also notify in writing the local mayor of Belle Isle, the local tourist office, the local lifeboat and the admiral of the French national lifeboat institution in Paris, the local council and the head admiral of the Atlantic fleet of the French navy of the dive teams intentions.

Our dive boat skipper Yann Quere being the secretary of the French national sailing organisation and a Moniteur 3 with FFESSM (the French equivalent of CFT in CMAS), would be of huge assistance and confirmed to the dive team that there were no restrictions in diving the wreck. In addition the Irish government had not even requested an exclusion order be placed on the site to preserve the Asgard II, meaning it could be legally dived by any dive team at any time.

During the last few weeks endless hours would be spent reviewing the vessels plans, photographs and video clips; trying to decide what obstacles could lay ahead in trying to video and photograph the wreck as well as removing the bell, helm and compass. Eoin would even go so far as contacting Tyrell's to get the specifications of how the wheel was fitted and what size bolts were used to bolt the bell on.

A specialist dive tool bag was then assembled with all anticipated tools colour coded and placed into the bag in the order of their anticipated use; to try and eliminate wasting any precious bottom time. Only a few weeks to go and word came that a French technical dive team also had their eyes set on the Asgard II, would we arrive to late and would all the artefacts have disappeared into the possession of French or British divers; only time would tell.

Being Jury president of the CFT Moniteur 3 test on Inisboffin the day before the trip to France, my preparation time was hardly ideal; getting home after 10 pm on Friday then having to blend several mixes and assemble camera and rebreather equipment; grab a precious five hours sleep and head for the ferry. Seeing familiar faces of friends and dive buddies all thoughts of fatigue soon evaporated in anticipation of a good weeks diving. During the last week Paddy Agnew also joined the group and would assist Stephane on the surface during the course of the week.

Arriving in the idyllic harbour of Belle Isle the sight of the Irish Tricolour flying from the tourist office on our behalf was a good omen. That evening our skipper told us the water would be warm, the sea flat calm and visibility would be at least 10 meters with ambient light at depth; and we headed to bed in good spirits for an early start. Leaving the harbour with a strengthening breeze we would soon be greeted by a stiff force five and with cylinders rolling around at the stern of our dive boat; conditions were marginal as a small blob at 84 meters showed up on the screen of the GPS.

Our next concern would be the number of prawn trawlers that were fishing quite close by in the direction we anticipated our decompression station moving. With the Bay of Biscay having notoriously unpredictable weather it seemed that we would be treated to diving conditions more reminiscent of the south coast of Ireland. After an arduous time kitting up in a pitching sea in a dive boat, which doesn't normally cater for technical divers; the cooling effect of the sea came as welcome relief as Eoin Mc Garry and I dived first. Eoin would be taking video footage and I would be taking stills with my Ikelite camera housing rated to 60 meters, hopefully it would not leak at 84 metres! (at least the strobe was rated to 90 meters).

Dropping through layers of water the temperature soon dropped from 19 on the surface to 9 degrees Celsius at depth, the biggest surprise however being the visibility. Beyond 60 meters ambient light disappeared and visibility reduced to less than 1.5 meters; Irish diving conditions indeed. Landing on the Asgard II we could immediately see that our anchor line was perilously attached to the wreck and in danger of coming loose: something that was soon rectified. After adapting ourselves to the conditions it was good to see that my camera was surviving at 9 bar (at least for the moment) and we soon set off taking footage with Eoin taking video. Dropping down past the stern came the worm encrusted letters of Asgard II and swimming the length of the vessel it was soon apparent that she was in a sorry state. Both masts had collapsed and she had been badly damaged by trawlers; with one mast landing on the compass binnacle and the roof of the chart completely missing and almanacs aplenty neatly stacked in the shelves.

Amid the books and almanacs and nestled with a menacing grimace a large conger eel now stood sentinel in its new citadel. At the bow area it was a sorry sight to see the bowsprit of Grainne Uaile partially hidden by old sail, doomed forever to the seafloor. Swimming astern the sight of the ships helm still lashed was an amazing image that would cause all divers to become exuberant and all too soon our precious bottom time had elapsed and it was time for the mandatory 2 hours of decompression. Passing the second dive team who were also taking video footage the warm thermo clime was a welcome change from Irish diving conditions, but a strong surface current soon tempered that dramatically.

Back at the decompression station it was a strange sight to see that the strength of the current had orientated the decompression station at a 45-degree angle and instantly knew that the first hours decompression would be far from comfortable (until the second dive team had set the decompression station free in the current). Looking across at Eoin I could see the sight of the ships compass nestled safely in a bag, eliminating one of the objectives for day two. Surfacing to warm sunshine and with greatly moderated sea conditions we were soon planning dive objectives for day 2, pondering the difficulties of removing the ships bell and helm.

On unloading the boat back at Belle Isle we would have two groups of visitors, both unexpected. The first group were survivors of the sinking who had returned to Belle Isle sailing aboard the magnificent Le Belem and soon we were showing them the footage of the vessel they so hastily had to abandon.

The sight of two gendarmes taking to Stephane had the rest of us wondering what was happening, when it quickly emerged that a complaint had been received by the French police from an Irish government agency asking for the diving to be halted. While the rest of us blended gas and organised logistics for day two, Eoin and Stephane had very cordial discussion with French gendarmes who said we might not be able to dive the wreck later in the week.

The next morning with a 6 am start we were soon heading for the wreck site (with the Irish tricolour again flying from our dive boats mast) and were soon onsite. With the possibility of only one dive left on the Asgard II, dive objectives had to be reassigned and all divers were again assigned to two dive teams and we were soon descending a shot line in strong currents.

Approaching the ships hull seeing bubbles coming from my cameras strobe were not a welcome sight and I wondered would it work filled with seawater and found it did. The camera housing rated to 60m meters survived both dives unscathed; with the expert advice I had received on underwater photography earlier in the year from Ivan Donoghue, Simon Carolan and Nigel Moyter proving invaluable on the trip.

During this dive the dive team would again get video footage, which was given to the marine casualty investigation board for their report as well as getting more stills footage. Frank Mc Kenna soon had the ships bell and bracket removed and soon it was attached to a lifting bag and heading for the surface 84 meters above. Eoins' huge amount of prior research was soon hugely rewarded when the ships helm was also heading to the surface where Stephane Portrait was waiting to recover them.

The final act of the dive team would be to leave an Irish tricolour on a vessel whose name has such symbolism in Irish history, when Irish men and women overcame impossible odds to defeat the greatest empire on the globe to establish an Irish state after 700 years of struggle. The tricolour left draped on the wreck had been a gift from an ex member of the Irish Defence Forces and had last flown over and Irish Military Establishment and would serve as a fitting tribute to a vessel that had so eloquently represented Ireland in a maritime setting. Back aboard our dive vessel it was good to see that everyone had completed their decompression safely and that all objectives had been completed, with Stephane doing Trojan work for the bottom divers.

Once back ashore we would be astounded to hear of sensationalist newspaper headlines back home; giving a completely inaccurate version of events. That evening Eoin and Stephane would declare the artefacts to the equivalent of the French receiver of wrecks and would be told that the matter had been referred to the commodore of the local French naval base in Brest.

The following day the gendarmes would give the dive team a copy of a fax from the French naval base which confirmed that the dive team had broken no laws French or otherwise as we had known all along and the French gendarmes apologised for any inconvenience caused (that they had been acting on a fax from an Irish government body which was furnished to the dive team) and wished the dive team well.

Over the next few days of pleasure diving shallower wrecks two surprises would arise; the first that the visibility at the other end of the island was in stark contrast to that where the Asgard II lies and was typically twenty meters at depth!!! and secondly that the artefacts that we had previously been told were valueless were now suddenly of huge interest to Coiste an Asgard. Indeed it would puzzle everyone on the dive team at how helpful the French authorities were which was in stark contrast to their Irish counterparts; whom it would seem would have preferred to see these items disappear into the hands of continental or British dive teams. In the interim Eoin had got expert archaeological opinion in how best to preserve the wheel and spent a considerable sum of his own money in making a specialist box to ensure we could transport it in a wet condition back to Ireland.

Once back home the huge cascade of congratulatory messages to the dive team was a nice boost and made all the financial and personal sacrifice very worthwhile, as the volume of people with an interest in Irish maritime affairs soon became apparent. Back on Irish soil, the artefacts were registered with the Irish receiver of wrecks and handed over to him in custody as per maritime and salvage law. Hopefully in time these symbols of Irish maritime history and pride will be put on permanent display in a fitting venue such as the national museum next to the original Asgard or in Dun Laoghaire at the national maritime museum; where the 10,000 trainees who first learned to sail a tall ship aboard Asgard II can again hold that famous wheel or ring the bell.

Of all aspects of scuba diving, the discipline with the highest mortality rate is cave diving writes Timmy Carey. A myriad of things can go wrong, a diver can get lost, run out of air and even worse, carried out in complete darkness if the diver loses their lights. On Friday, the 3rd of December N.U.I.G G.M.I.T Sub Aqua club will be hosting a free lecture on cave diving. The lecture will be presented by Artur Kozlowski and has made a large number of caving breakthroughs in Irish cave systems.

In 2008 he broke the British and Irish depth record in a cave at 103 meters and the lecture promises to be very interesting. The venue is D'arcy Thompson (on the main concourse) in N.U.I Galway.

Embedded in the history of Ireland, the events which occurred in April 1916 place Roger Casement and his famous gun running ship in the annals of Irish history. She lies broken, in a depth 34 metres in Cork Harbour. Much of the cargo of 20,000 guns and 1,000,000 rounds ammunitions still remain writes Timmy Carey. The ship was scuttled by her captain Karl Spindler rather than hand the cargo to the British. This would be the only German naval surface ship to enter Irish waters during World War 1. The wreck was depth charged on a number of occasions to make sure that the weapons were scattered and made unrecoverable by rebel forces and to prevent submarines using the wreck as cover. The rifles and much of the ammunition originated in Russia. They were captured as a result of the rout of Russian forces at the battle of Tannenburg in 1914.

This coming Friday night Blackwater Sub Aqua Club in Fermoy will host a lecture on the Aud by author Xander Clayton. Xander is a researcher of Modern Irish history and is the leading authority on the Casement Ship. He has made a detailed study of the ship and her 22 man crew over the past quarter century, culminating with the publication of the book "AUD" in 2007. He now lives in Ireland and the second edition of his book is due for imminent publication. The lecture will start at 20:00 and is free of charge. The venue is Blackwater Sub Aqua Clubhouse, Rathealy Road, Fermoy. For further information contact Matthew Culotty 087-8217069.

On the 14th of October 1918, 20 people from Dundalk lost their lives aboard SS Dundalk when it sunk 60 miles south of the Isle of Man writes Timmy Carey. Earlier this year to mark the 92nd anniversary of the loss a number of Dundalk Sub Aqua Club divers carried out a commemorative dive to the wreck and laid a plaque of remembrance sponsored by Dundalk town council.
The team also placed an air tight capsule containing objects from the relatives of the survivors and those lost on the tragic ship.

Some artifacts were removed from the wreck and brought home to Dundalk and the team donated them to the local museum where they made a presentation of the expedition and showed some underwater footage of the wreck in its current state. The presentation was held on 14th October to mark the 92nd anniversary of the sinking and the team were joined by some relatives and members of the public for an emotional night with prayers and music provided by Fr Clem McManus a local Redemptorist Priest.

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.
