Dredging work is about to begin at the Port of Waterford with a maintenance dredging campaign to be carried out by a Dutch company.

Baggerbedrijf De Boer B.V.'s trailing suction hopper dredger Amazone is next week to conduct activities in the vicinity of Belview, Cheekpoint and further down in the estuary at the Duncannon Bar.

The campaign's main objective is the removal of accumulated sediment from the channels, turning areas and berths at (Belview) the main terminal at the Port of Waterford. This work will mostly involve work at the Cheekpoint lower bar and also at the Duncannon Bar.

The removed material will then be disposed by the 2771m3 hopper capacity dredger at an approved site beyond the estuary at a location south west of Hook Head.

It is expected that the campaign will take approximately 28 days and be followed by a bed levelling works by the Fastnet Sound which Afloat adds is a 21m MulitCat operated by a local firm Fastnet Shipping.

The marine plant and services company is based on the River Suir at Bilberry which is just westward of Waterford city's Rice lift-bridge.

One of the country’s leading marinas will become unusable for keelboats unless urgent action is taken to address increasing silting in the harbour area writes David Forsythe in West Cork

Kinsale-based Fine Gael councillor Kevin Murphy told the recent meeting of Cork County Council’s Western Division that the issue was among the most serious he had ever had to bring to the attention of the council.

“The story is that Kinsale Harbour itself has severe silting at the yacht marina and around pier head itself. A substantial number of the keelboats are bottoming out now. This is a very serious issue and a very expensive one to sort out because there is a substantial dredging to be done,” he said.

Matthias Hellstern, Commodore of the Kinsale Yacht Club said that the issue had become much more serious in the last few years and the rate of silting in Kinsale Harbour seemed to be increasing.
“During Covid there was obviously a lot less activity at the marina and in the harbour in general because of the restrictions. It has been happening over a number of years but seems to be getting much worse now. It is something that we really need to address urgently,” he said.

The 200 berth marina brings in some 3,500 visiting boat nights to the town every year contributing an estimated €525,000 to the local economy according to the yacht club’s own estimates. A non-profit organisation run by volunteers, it is one of only three yacht clubs in the country that owns its own marina, the others being Howth Yacht Club and the Royal Cork Yacht Club in Crosshaven.
“We have visitors coming from France, the UK, Spain, Germany, the USA and all around Ireland,” said Matthias Hellstern, “and we run also run national and international sailing championships which we could not do without the marina facility.”

The KYC is due to host the upcoming Squib UK National Championships, Dragon Gold Cup and also hosts the biennial Sovereign’s Cup, but silting is already causing problems for events in Kinsale.
“We hosted the April Spring series recently and we were having yachts running aground at low tide,” said Matthias, “they simply couldn’t get out of the marina and obviously that’s a serious problem.”
Mr Hellstern said that already about 25% of the marina was not useable for keelboats at low tide.

“At the moment we can move things around a bit. The berths furthest from the channel are most affected so we can put power boats, boats without keels in there for the time being but as the silting gets worse more and more of the marina will be affected.”

Cllr Kevin Murphy said that silting was affecting other users of the harbour as well across leisure, fishing and commercial sectors.

“We have to at all times ensure Kinsale continues being useable for leisure and also commercial and fishing, it’s all three. The Kinsale Yacht Club will help out with a survey that needs to be done on the silting and I would expect that the county council will also chip in if we can to help out in their endeavours to get that done as soon as possible.”

Cllr Murphy said that he would put down a notice of motion at the next municipal district meeting to have all of the stakeholders attend a meeting at Kinsale Yacht Club, “to make sure this is addressed as soon as possible”.

Responding to Cllr Murphy, Kevin Morey, Director of Water Services at Cork County Council said, “We will engage just to take stock and see what is the issue there. From your description, it sounds like it might be quite a significant one and we are aware from other locations that that could bring us into quite complex and protracted processes. Let’s start looking first and take stock so we’ll get back to you on that and arrange some kind of assessment on site.”

Environmental campaigners have hit out at a Stormont decision to approve sand dredging in Lough Neagh, as the Belfast Telegraph reports.

Sand dredging has been practiced in Lough Neagh since the 1930s, with no permission needed until after the lough was designated as a Special Protection Area for wildlife in 1999.

Most recently the practice has been subject of a years-long legal battle, as previously reported on Afloat.ie, with Friends of the Earth claiming that as much as 1.5 million tonnes of sand are removed from the lough each year.

The final say on the matter was left to Northern Ireland’s Department of Infrastructure, whose minister Nichola Mallon signed off on the approval and said the decision was a “finely balanced” one “where I had to weigh up the various benefits with the potential for harm to the designation features of the lough”.

Among those criticising the move was Green Party NI leader Clare Bailey.

She said that sand dredging has “a devastating impact on the entire ecosystem of the lough”, and claimed the situation underscored the notion that “Northern Ireland is disintegrating into an environmental wasteland”.

The Belfast Telegraph has more on the story HERE.

The Dublin Port Company has given notice that maintenance dredging will take place between Alexandra Basin and the Dublin Bay Buoy from tomorrow, Thursday 10 September.

Four weeks of dredging works are scheduled in the fairway and berth pockets from the buoy to a line drawn due south of berth OB1 and including Alexandra Basin East.

Three vessels will be involved in the dredging works: the trailing suction hopper dredger Shoalway; the survey vessel Smit Neyland; and Norma, a bed-levelling plough.

The three craft will maintain a listening watch on VHF Channel 12 and show the required lights and shapes.

All other vessels should pass at slow speed and make due allowance for their operations and restricted manoeuvrability.

The Port of Cork reminds mariners that maintenance dredging will be taking place in Cork Harbour on all main shipping channels and berths from this Wednesday 19 August.

As previously reported on Afloat.ie, the dredging campaign by the TSHD Taccola will progress 24 hours a day until late September.

It follows a prior survey conducted last week, and bed levelling operations which began yesterday, Sunday 16 August.

Mariners are requested to navigate with caution when in the vicinity of the work craft, to pass by as wide a margin as possible and proceed with minimum wash and speed.

A maintenance dredging campaign has begun in recent days at the Port of Waterford where activities will involve the waters of Duncannon Bar, Cheekpoint, and at the port's main terminal at Belview, writes Jehan Ashmore

Prior to the operations at the south-east port, the Cypriot flagged Shoalway, a trailing suction hopper dredger had been carrying out operations for the Dublin Port Company. Shoalway sailed from the capital to arrive on the Waterford Estuary on Sunday. 

According to the Port of Waterford (click to consult campaign notice here), the dredger will dispose spoil at an approved site south west of Hook Head, Co. Wexford. Dredging will be followed by a bed levelling campaign by the vessels, Fastnet Sound and or the Glenesk.

Afloat adds that Irish Dredging which is a subsidiary of Royal Boskalis Westminster nv, the world’s largest dredging group, was given the contract from the Port of Waterford. The extensive fleet of the Dutch group provides Irish Dredging access to the use a of wide range of vessels for projects around the Irish coast.

Further tracking of the Shoalway since introduction on the Waterford Estaury has seen the 90m long dredger kept busy between Cheekpoint to the spoiling grounds out to sea.

The campaign according to the Port of Waterford is expected to last approximately 24 days.

#Irishports - The Port of Waterford have issued a Marine Notice in recent days to advise all ship owners, shipmasters, agents, fishing vessels, pleasure craft users, seafarers and fishery organisations of a dredging campaign, writes Jehan Ashmore.

The dredging operation along Waterford Estuary began in mid-March and according to the south-east multi-modal Port the campaign will continue until around 6 April.

Carrying out these works is the task of trailing suction hopper dredger Freeway which will conduct dredging activities in the vicinity of Belview Port. The lo-lo facility located downriver of Waterford City is the main port along the estuary.

Freeway is operated by UK firm, Royal Boskalis Westminster based in Hampshire. They are no strangers to these waters having been contracted previously by the port and more recently from the Dublin Port Company. Due to berth capacity constraints the 92m dredger during December had to dock in Dun Laoghaire Harbour.

On this occasion, Freeway's role on Waterford Estuary will include duties carried off Cheekpoint and at the Duncannon Bar located further downriver and beyond where the Passage East ferry links to Ballyhack.

Disposal material from Freeway will take place at an approved site south west of Hook Head. Following such work a bed-levelling campaign will be assigned to the Waterford City based catamaran craft Fastnet Sound.

The Department of Agriculture, Food and the Marine has updated local Fingal councillors on its proposals for the dredging of Howth Harbour.

On his Facebook page, Cllr Cian O’Callaghan says the meeting with the department and the Howth Harbour Master on Wednesday (6 March) detailed a plan to dredge five key areas of the harbour, namely:

  • The fishing trawler basin between the West Pier and Middle Pier
  • The approach channel at the mouth of the harbour
  • The marina used by Howth Yacht Club
  • The approach channel to the marina
  • The outer moorings area which is used by the Howth Sailing and Boat Club

This would result in the extraction of 225,000 cubic metres of silt, the equivalent of up to 30,000 lorry loads, says Cllr O’Callaghan.

The detailed plan follows testing of material extracted from the harbour which confirms that while is it contaminated by general harbour activity, it is not considered hazardous.

It is being proposed that the spoil be treated and used to create a 100-metre-wide infill area along the west side of the present West Pier. Plans for the use of this new space have not yet been decided but it is expected there will be a relevant public consultation by year’s end.

Four months ago the tender period closed for engineering services related to these long-awaited dreading works in the North Co Dublin harbour.

Monday 12 November is the final date for receipt of tenders for engineering services for the long-awaited dredging of Howth Harbour.

Howth Yacht Club Commodore Joe McPeake has confirmed the date after contact with the Department of Transport, Tourism and Sport.

It is believed that consultants will be appointed within two weeks of tender closing date, and that they will engage with harbour stakeholders early in the new year to discuss issues such as minimising disruption to harbour operations, including the moorings and marina.

While no clear timeframe is available as yet, Commodore McPeake expects the initial stage towards securing licensing and planning permission to take 12 to 15 months, pending any potential challenges.

Following that, dredging works could take up to 18 months to complete, including works at both piers in Howth.

“As soon as the engineers have been appointed we will seek to meet with them to scope out their plan to methodology and review its implications for us,” said Commodore McPeake, who expects to further update Howth Yacht Club members in February.

#Ports&Shipping - The second largest port in Northern Ireland, Warrenpoint Port, is inviting members of the public and other key stakeholders to comment on proposed changes to how dredged material from the harbour is dealt with.

The Co. Down port currently carries out a major dredging programme every two to five years with material disposed of in the Irish Sea.

However, new plans have been put forward to carry out dredging on a more regular but smaller scale, with material placed at a site in the mouth of Carlingford Lough between Cranfield Point and Greencastle.

Clare Guinness, CEO, Warrenpoint Port said: “In order for the Port to continue to support maritime trade successfully, it must ensure a sufficient water depth is maintained to allow for the safe berthing of vessels, which it does through dredging.

“In anticipation of a rise in trade over the coming years, and to ensure the Port continues to thrive as an economic driver to the local region, a new site for the disposal of dredged material is being proposed within the mouth of Carlingford Lough.

“This is also in line with current thinking that dredged material should be deposited as close as possible to source.

“In our role as a custodian of the marine environment, we want to hear the views of all stakeholders, including members of the public, before any plans are put into action.”

A number of surveys, studies and assessments will be undertaken to determine the suitability of the location between Cranfield Point and Greencastle, including marine ecology and sediment surveys, geophysical surveys, and hydrodynamic and sediment transport modelling.

A public drop-in consultation event will take place at Warrenpoint Town Hall on Wednesday 19th September from 4pm to 7pm. There will be an opportunity to discuss the proposed disposal site and the environmental assessment process with Port staff and its consultants Royal HaskoningDHV.

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.
