#TurbineToGo - A tidal energy turbine is to be removed from Strangford Lough, Co. Down, reports BBC News.

The SeaGen turbine was lowered into place in 2008 (see report photo) and generates electricity from tidal currents.

Two horizontal axis turbines are anchored to the seabed and are driven by the powerful currents resulting from the tide moving in and out.

Its owners Atlantis Resources (only since July, 2015) said it will be decommissioned later this year.

The company said it had been "an essential research and design platform".

Stephen Ward, the firm's director of power generation, said: "This year, we will embark on the next stage of the R&D (research and development) process and focus on decommissioning the SeaGen device.

"This operation will be the first commercial scale turbine development to be decommissioned and will help us to understand the complete life-cycle of a tidal stream development."

Strangford Lough will stage the coastal rowing Skiffie World Championships  2016 this July.

Canada, England, New Zealand, Northern Ireland, Scotland, Tasmania, USA, Wales will bring a truly international flavour to the six day rowing event featuring 22ft, traditionally styled, wooden St Ayles skiffs, rowed by teams of four people plus cox.

Strangford Lough and Lecale Partnership, Scottish Coastal Rowing Association, Newry, Mourne and Down District Council and Ards and North Down Borough Council will welcome the coastal rowers to Strangford Lough from 24 -30 July 2016

All of the St Ayles’ skiffs have been built within their communities, thanks to a system that allows even non specialist boat builders to produce a high specification, traditionally styled wooden, racing boat.

Each boat has its own colours and names that are evocative of their home-places. The building of them brought people together from all walks of life and of all ages. They symbolise the bonds that have been forged between people within communities and now through competition the shared maritime heritage that binds coastal people the world over.

County Down has become a centre for coastal rowing with seven clubs already established long the coast, from Donaghadee to Dundrum, and others being set up.

#BusCrash - HM Coastguard teams from Bangor and Portaferry were on the scene at Strangford Lough this morning (Wednesday 9 December) after a bus crashed from Portaferry Road onto the beach below.

No passengers were on board when the Ulsterbus crashed through a wall on the road outside Newtownards in Co Down just before 6.55am.

The driver was taken to hospital as workers cleared debris from the road and raced to recover the bus from the beach before high tide, as the Belfast Telegraph reports.

The Northern Ireland Environment Agency also sent officers to the scene to check for any pollution that may have occurred. The PSNI and ambulance service were also in attendance.

#FerryNews - Proposals to adjust the Strangford Lough ferry timetable are now under public consultation, as the News Letter reports.

The new schedule for October to April would see the cancellation of the last sailings from Strangford (at 10.30pm) and Portaferry (10.45pm), meaning both directions would see the last boat leave 30 minutes earlier on weekdays and Sundays.

However, the plans also see an additional year-round morning sailing from Portaferry to Strangford on weekdays at 7.20am.

#DiamondOnStrangford - 'Diamonds' the title to a track that would be familiar to worldwide fans of singer Rihanna, though less known was yesterday's visit of Ocean Diamond to Strangford Lough,Co. Down, writes Jehan Ashmore.

This was understood to be Ocean Diamond's maiden visit to the north under the operation of Quark Expeditions, whose fleet of small ships specialise in Arctic and Antarctic adventure style cruising.

She made a transit through the scenic 'Narrows' as the name suggest is located between the stretch of water between the open sea and lough. Also along these shores is where the villages of Strangford and Portaferry face each other and are connected by car-ferry.

The expedition-polar cruiseship equipped with Zodiacs stowed at the stern then proceeded into Strangford Lough to anchor off the southern side of the scenic shoreline. The lough represents the largest inlet of either these Atlantic Isles, covering 150 km².

The blue hulled livery of Ocean Diamond had previously been an all-white affair commonplace with cruiseships when she was the La Diamant. Arguably she was better known in Irish waters when she held the name Song of Flower.

On Tuesday the 8,482 tonnes Ocean Diamond also made her maiden call to Waterford City where she berthed at the crystal city albeit on the north quays of the Suir. It is understood this was the second out of 18 callers due this season.

The Irish connection with the ship continues in the form of Quark Expeditions new loyalty program marketed as The Shackleton Club. The choice of the club's name is in honour of one of Antarctica's greatest explorers, and created to inspire guests to keep on cruising.

Ocean Diamond in exterior design terms is more that of robust looking super-yacht, and one of the largest of Quark's small expedition ships. She has a maximum of 189 passengers, and with two stabilizers and an ice-strengthened hull, the 1974 built vessel is suited for polar expeditions.

According to Quark, she is one of the newest, fastest, and most eco-friendly ships in Antarctica. There are 101 designed cabins and suites, all with exterior views, and expansive common spaces, a club lounge, and a spacious restaurant.

The ship offers numerous adventure options, plus on-board features such as interactions with photography instructors. After a full day of exploration, passengers can relax, browse books or DVDs in the polar library, or enjoy stunning polar scenery from the sun-lit, panoramic observation lounge.

The marketing publicity for the Ocean Diamond says her passengers travel to one of the world's most remote destinations will also do so in a "greener" fashion. That is to say that Ocean Diamond is the first ship in Antarctica, and in polar travel history, to offer certified CarbonNeutral® voyages.

#MarineWildlife - Northern Ireland acted too slowly to protect endangered horse mussels in Strangford Lough, according to a new report.

The findings by the Northern Ireland Audit Office, as the News Letter reports, have damned Stormont's failure to ensure proper implementation of various plans to protect the mussel reefs since the 1980s.

As previously reported on Afloat.ie, it's not the first time the NI government has been criticised for inaction over the protected shellfish species.

A study from Queen's University Belfast in 2011 revealed the extent of damage to their habitat by commercial fishing.

Since then, the lough has faced the additional threat of the invasive Japanese sea squirt.

A revised restoration plan was drawn up in 2012 between the Department of Agriculture and Rural Affairs (Dard) and the Department of the Environment (DoE), which share responsibility for Strangford Lough.

But the European Commission is taking seriously previous complaints made against Stormont by the Ulster Wildlife Trust, with the potential for millions in fines to be levied if any future complaint is upheld.

#CoastalNotes - The history of Strangford Lough stretching back some 10,000 years is the subject of a 'spiritual motorcycle journey' by local writer Peter Moore, as the News Letter reports.

Moore, a motorbike enthusiast and archaeology graduate, hopes his new book, Valhalla and Fjörd, will inspire others to "further explore the area and enjoy the stories" relating to the "wonderful history in and around" the scenic lough.

“At the start of this journey I was unaware of just how much history there was to uncover around Strangford Lough and the fascinating stories of those that lived here over the past 10,000 years," he says of his project, which he hopes to be the first in a series of books.

Moore's journey took him on his restored Triumph motorcycle via old monastic sites, ruined abbeys and churches and other unmarked settlements around the shores of the Co Down inlet, which takes its name from the Norse for 'strong ford' after its powerful tidal currents.

#MarineWildlife - Marine researchers captured a first for Strangford Lough last week when they filmed a pair of short-beaked dolphins frolicking in the waters.

According to the Belfast Telegraph, the scientists from Queen's University were on the lough to collect seaweed samples last Wednesday morning (5 November) when they were surprised by the sight of the playful marine mammals, and took out a smartphone to film their breaching, rolling and belly-flopping antics.

Little did they know at the time that they'd recorded the first ever validated sighting of the short-beaked common dolphin in Strangford Lough, and only the second ever record of the species on the Co Down coast.

#flyingfifteen – The Flying Fifteen Championships of Ireland take place in Portaferry Sailing Club on Strangford Lough tomorrow. Up to 30 boats are expected with boats travelling from four sailing centres across Ireland; Antrim, Carlingford, Dun Laoghaire and Dunmore East.

Reigning National champions Ian Mathews & Keith Poole of Dun Laoghaire will be one of the favourites. Local knowledge is expected to play a deciding role. Class President Roger Chamberlain from the lough is in great form and won the recent Northern Championships. Brian McKee and the David McClery and Colin Dougan combination are as consistent as ever as are Peter Lawson and Shane Carty from the local Portaferry Sailing Club.

Also from Dun Laoghaire previous winners David Gorman and Chris Doorly, National YC (NYC) and John Lavery and David O'Brien (NYC) will also be competing. 

The Northern Ireland venue featured last week in WM Nixon's Sailing blog: Strangford Lough Sailing Secrets Revealed.

#strangfordlough – It's most encouraging to see such interest in the magic of Strangford Lough writes W M Nixon and if we missed out on some aspects of it in reviewing our time there (see blog and comments here), it was only because we had already so much material on the agenda of primarily dealing with the Rivers and the GP 14s.

I take Theo Rye's point that the Linton Hope-designed Dabchicks of 1895 were probably the world's earliest one design class with Bermudan rig, but would plead that I think I meant to describe the Rivers as the world's first one design keelboat class with Bermudan rig (well, he would say that, wouldn't he?).

As for William Jenkins pointing out that Glens were also racing that night of Wednesday August 13th, so too in a combined class were the RS Elites and Flying Fifteens. The Glens, like the Rivers, had good racing, but here too one boat was dominant, Glenlark sailed by Richard Aitken whose family have owned the boat from new, his crew including Irish Cruising Club Vice Commodore Alan Leonard.

The Strangford Lough Glens are on something of a roll these days, as this past weekend (August 16th & 17th) they had their annual team racing series against the Dun Laoghaire Glens, and though it was an away match for the Whiterock squad which was captained by SLYC Commodore Ian Gleadhill, they won overall in a series which was curtailed by Sunday's foul weather.

As for the quality of the courses and the race management at Whiterock on the night of Wednesday 13th August, the photos speak for themselves. Racing started in a brisk and sunlit nor'wester, the course provided two excellent long beats and lots of spinnaker work, and it was all neatly wrapped up after sunset but with every boat finishing the course despite the dying breeze and gathering darkness. It was club evening racing at its very best, and the banter at the tasty post-race supper in the clubhouse rounded out an excellent programme.

glen4.jpg

Evening racing timed to perfection. In the long-drawn-out northern sunset, Richard Aitken's Glenlark arrives in the lead at the weather mark. SLYC uses simple but clever ballasted plastic piping racemarks, and even when the tide is across them a displacement boat will find she has a very forgiving cushion of water between mark and boat when trying to shoot the turn.

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.
