“We’ll always give our best, treat every incident as if it is one of our own.... and try our utmost to get a missing family member back to their loved one.....”

The words of Lieut Stephen Stack, head of the Naval Service diving unit, speaking about what keeps his colleague “motivated and driven to succeed”.

Last year, Sub-Lieut Tahlia Britton from Rossnowlagh, Co Donegal, became the first female to qualify for the Naval Service diving unit. A former champion surfer, she studied podiatry at NUI Galway but always wanted to join the military.

She has described the mental and physical challenges of being a Navy diver in an interview recorded for RTÉ Seascapes, the full version of which is on a Wavelengths podcast this week (below).

Search and recovery is just one aspect of the work of Navy divers, which is, as Stack says “not glamorous...”

One of the team’s recent challenging operations was the three-week-long search after the 12-metre steel-hulled boat, Alize, fishing out of Duncannon, Co Wexford, went down some 6½ miles off Hook Head, Co Wexford just over a year ago on January 4th, 2020.

Joe Sinnott (65) from Kilmore Quay was recovered off Duncannon by the Irish Coast Guard Waterford-based Rescue 117 helicopter.

The body of skipper Willie Whelan (41), recently married and from Fethard-on-Sea, was located by the Hook Sub Aqua Club, and it was taken from the wreck of the new vessel by the Naval Service diving team.

“It was in very deep water, it was very complex, the weather wasn’t great, “Lieut Stack said, describing it as technically the most challenging operation he had been involved in recently.

He has paid tribute to the Garda Water Unit and the voluntary search and recovery groups that the Navy divers also work with in their aid to civil power role.

You can hear a taste of the aptitude test which aspiring Navy divers have to undergo at the Naval Service base at Haulbowline, along with interviews with Stack and Britton – including what she might sing underwater - below

Coincidence is amazing, even if it's hard to believe. This week I'm inclined to credibility after Foreign Affairs, and Defence Minister Simon Coveney espoused the importance of the Naval Reserve when announcing the Government decision to establish a Commission "to ensure that the Defence Forces are fit for purpose" and then hearing that the same Reserve had used the 'god of the sea' - Neptune - for a purpose never thought of in the maritime world – to please the American Navy and bring the game of basketball to Ireland!

Minister Coveney, himself a Cork Harbour man, emphasised the importance of the Reserve, which was formerly known as the Slua Muiri and had its own yacht, the Nancy Bet.

Nancy Bet in 1987Nancy Bet in 1987

I had just met another Corkman for my Maritime Ireland radio show, who told me that the Navy and the Slua had been used by the Irish government after the end of the Second World War to ease anti-Irish sentiment over Ireland's neutrality in that conflict, when the American Navy visited Cork Harbour.

"Recreational exchange with the visitors was arranged through their favourite game, basketball and the Navy was instructed to make sure it happened and to develop public interest. The Maritime Inscription of the time, then the Slua, was handed the task and they invoked the 'god of the sea' – Neptune – to make it all happen," said another Corkman, Jim O'Donoghue, who showed me the cover of the new history he has written of what became Ireland's leading basketball club, which shows Neptune in a pose no mariner would have expected – holding his trident in one hand and a basketball in the other.

It is a fascinating story and for those who would like to read more the book, 'Gods of the Lee,' is available at, Vibes & Scribes, Bandon and Carrigaline Book Stores and Amazon.

Listen to the Podcast below, a preview specially for Afloat readers, linking mariners, Naval forces and sport and leading me to make further checks about the Slua Muiri vessel, Nancy Bet, which was at Crosshaven Boatyard for many years before being removed to Arklow where I understand she now is.

Spencer Jetty in Haulbowline Naval Base in Cork Harbour is to be upgraded to provide for the berthage requirements for the Naval Service fleet.

The Minister for Defence, Mr Simon Coveney T.D., has announced the funding consists of:

  • Remedial and strengthening works to the steel piles and concrete deck
  • Construction of a raised turning area/parking zone and access ramp to the Jetty
  • Upgrading of bollards, rails and ladders
  • Provision of new fendering

The Spencer Jetty Upgrade will stabilise the currently unusable Jetty structure and protect the sea entrance to the NS Dockyard and Basin. The upgraded facility will also provide the Naval Service with an additional short term berth.

The project is part of the Plan to increase berthing capacity for the current fleet in three distinct standalone infrastructural projects, with the Spencer Jetty Upgrade delivered as Phase 1. All of these projects are included in the 5-year Infrastructure Development Plan.

Minister Coveney stated that the refurbishment and upgrading of the facility is being undertaken as part of the 5-year Infrastructure Development Plan which was announced earlier this year. Today’s announcement is part of a suite of investments we are making in our Defence Forces over the next 5 years, to ensure that our Defence Forces are enabled to contribute fully to their assigned roles.

Commencement of construction work on-site is planned for before the end of the year with the works expected to take one year to complete.

This project provides for an investment of some €1.4m (excl VAT) to provide for the berthage needs at Haulbowline.

 A French-registered fishing vessel has been detained by the Naval Service patrol ship LÉ William Butler Yeats (P63) off the south-west coast.

The detention approximately 45 nautical miles south-west of Mizen Head was in relation to alleged breaches of fishing regulations, according to the Defence Forces press office.

The vessel is being escorted to Castletownbere, Co Cork, where it will be handed over to the Garda.

It is the 12th vessel detained by the Naval Service in 2020, working with the Sea Fisheries Protection Authority.

As Afloat reported previously, the LÉ William Butler Yeats also detained a French fishing vessel in July, off the Blaskets.

Gardaí are investigating an incident where a body was recovered offshore from Dun Laoghaire Harbour, on Dublin Bay yesterday, (Friday, 9th October). 

The Naval Service's coastal patrol vessel LÉ Ciara (P42) assisted with the recovery of the body.

The body of the deceased was taken to the local mortuary and, according to a Navy spokeswoman, the incident is now a matter for an Garda Siochana.

Enquiries are ongoing and there is no further information at this time, according to a Garda spokeswoman.

As Afloat reported yesterday, LE Ciara arrived into Dun Laoghaire Harbour yesterday at lunch-time, berthed overnight at number four berth and departed this morning (Saturday, October 10th).

Local sources told Afloat the body was of a female and was recovered well offshore but this was not confirmed.

The Naval Service is carrying out an internal investigation into the fire on board the LÉ Niamh moored alongside Cork Dockyard at Rushbrooke in Cork Harbour which occurred on Saturday.

As Afloat reported earlier, Fire service Units from Cobh, Midleton, and Cork City were called.

Defence Forces Press Office said no injuries to naval service personnel or Cork Dockyard staff.

"While a full investigation into the cause of the fire will be conducted, it is thought to have started in a stores compartment adjacent to where cutting work was being carried out by engineers," the spokesperson said."The ships Duty Watch responded to the alarm and carried out firefighting to contain the fire and prevent any spread.

A French-registered fishing vessel has been detained by the Naval Service off the south-west coast.

The LÉ William Butler Yeats (P63) detained the vessel for alleged breaches of fishing regulations after a boarding inspection approximately 11 nautical miles south-west of the Blasket Islands.

The vessel is being escorted to Dingle, Co Kerry, where it will be handed over the Garda, the Defence Forces press office said.

This is the eleventh vessel detained by the Naval Service in 2020.

A German-registered Spanish fishing vessel detained last week by the Naval Service near Rockall had been at the centre of an alleged confrontation off the Scottish coast last month.

As The Irish Examiner reports, the 29-metre Pesorsa Dos was detained by Irish navy patrol ship LÉ William Butler Yeats some 250 miles off Malin Head, Co Donegal for “alleged infringements of EU fishing regulations in Irish waters” on July 16th.

Orkney and Shetland MP Alistair Carmichael has highlighted the Irish detention, noting the British authorities said they could not take any action over an incident involving the same Spanish vessel off Scotland.

However, defence force sources have said the Irish detention was for a separate alleged infringement.

Video footage of the gill netter, from the Spanish port of La Coruna, filmed on June 11th, showed it allegedly trying to foul the propeller of a Scottish fishing vessel, Alison Kay, some 30 miles west of the Shetland islands.

The British Maritime and Coastguard Agency (MCA) was urged to investigate the incident, which Scottish skippers claimed to be the latest in a series of such confrontations over fishing grounds.

However, the MCA said it had no jurisdiction to investigate it as it was outside the 12-mile jurisdictional limit in which it could take action against foreign-flagged vessels.

It said its maritime investigations team had written to the German maritime administration “to raise its concerns”, as it was the responsibility of the flag state.

The German federal police department for maritime security has been reported as stating there is “no suspicion of an offence under German law”.

It is understood the vessel was gillnetting near Rockall, and had ten tonnes of monkfish on board when it was boarded and detained by the LÉ William Butler Yeats.

The vessel was escorted to Killybegs, Co Donegal and handed over to the Garda and the Sea Fisheries Protection Agency (SFPA).

Mr Carmichael said the fact that “the Irish authorities were able to detain the Pesorsa Dos entirely undermines the argument of the UK and German authorities that there was nothing to be done about its dangerous activities”.

He told the MCA in a letter that the actions of Spanish fishermen had “caused a great deal of anger and frustration for trawlermen in my constituency and across the north of Scotland in recent years”, due to both “aggressive acts such as those outlined, and the wider use of gill-nets which can cover large areas and thus prevent other fishermen from working in those areas”.

The SFPA said that a 24-hour detention order for the vessel was granted on July 21st at Carrick-on-Shannon district court in Co Leitrim. It said it could not comment further as the case was before the courts. It was the Naval Service’s seventh detention at sea this year.

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.
