#irishmaritimehistory –  It was a life which would have been remarkable by any standards, in any place, at any time. But in the Dublin of its era, this was a life of astonishing achievement against all the odds, in a rigidly structured society made even more conservative by a time of global unrest and national upheaval.

John Breslin Kearney (1879-1967) was born of a longshore family in the heart of Ringsend in Dublin, the eldest of four sons in a small house in Thorncastle Street. The crowded old houses backed onto the foreshore along the River Dodder in a relationship with the muddy inlet which was so intimate that at times of exceptional tidal surges, any ground floor rooms were at risk of flooding.

But at four of the houses, it enabled the back yards to be extended to become the boatyards of Foley, Murphy, Kearney and Smith. Other houses on Thorncastle Street provided space for riverside sail lofts, marine blacksmith workshops, traditional ropeworks, and all the other long-established specialist trades which served the needs of fishing boats, and the small vessels - rowed and sailed - with which the hobblers raced out into Dublin Bay and beyond to provide pilotage services for incoming ships. And increasingly, as Dublin acquired a growing middle class with the burgeoning wealth of the long Victorian era, the little boatyards along the Dodder also looked after the needs of the boats of the new breed of recreational summer sailors.

The young John Kearney was particularly interested in this aspect of activity at his father's boatyard, where he worked during time away from school. From an early age, he developed a natural ability as a boat and yacht designer, absorbing correspondence courses and testing his skills from 1897 onwards, when he designed and built his first 15ft sailing dinghy, aged just 18.

He was apprenticed in boat-building to Dublin Port & Docks across the river, qualifying as a master shipwright. But his talents were such that he rose to the top in all the areas of the port which required the designing and making of specialised structures, some of them very large. So in addition to building workboats of all sizes, he played a key role in projects like the new pile lighthouse at the North Bull, for which he developed support legs threaded like giant corkscrews, and rotated into the seabed like monster coachbolts.

Murphy's Boatyard on the Dodder in Ringsend in the rare old times is perfectly captured in this woodcut by Harry Kernoff RHA. It was all disappeared in 1954, when the old houses of Thorncastle Street were replaced by a complex of Corporation flats of such good quality that they have recently had a major refurbishment.

He also pioneered the use of reinforced concrete for pre-fabricated harbour constructions, and when the Great War broke out in 1914, his special talents and experience were called upon to advise on quick-build ferrocement structures of all kinds. Although Ireland remained neutral as World War II broke out in 1939, the Dublin engineering firm of Smith and Pearson established a yard in Warrenpoint just across the border to build concrete barges and small ships for war work, and John Kearney was their consultant.

So far-reaching was his input into developing the infrastructure of Dublin port that when he retired in 1944, while his official title was as Superintendent of Construction Works, he was de facto the Harbour Engineer. But he couldn't be properly acknowledged as such, because he had never qualified from a third level college - it was far from universities that the Kearneys of Ringsend were reared.

However, this lack of an official title left him unfazed, for his retirement at the age of 65 meant he could concentrate full-time on his parallel career as a yacht designer, something that was so important to him that when his gravestone was erected in Glasnevin in 1967, it simply stated: John Kearney, Yacht Designer.

He had developed his skills in this area ever since his first boat in 1897. In 1901, when he was still 21, a 17ft clinker-built canoe yawl, the Satanella which Kearney designed and built for noted Dublin Bay sailor Pat Walsh, was praised in the London yachting press. Her owner camping-cruised this little boat successfully along the great rivers of Europe before World War 1, getting there simply by sailing his canoe from Dun Laoghaire into Dublin Docks, and striking a shipping deal with whichever ship's captain was heading for a port on the desired river.

Kearney had been busy for the ensuing nine years with his growing responsibilities in Dublin Port. But in 1910 he reserved a corner of Murphy's Yard, and in the next eighteen months, working in his spare time entirely by hand with the light of oil lamps, he built his first personal dreamship, the 36ft gaff yawl Ainmara, to his own design. In this his first proper yacht, he immediately achieved the Kearney hallmark of a handsome hull which looks good from any angle, a seakindly boat which was gentle with her crew yet had that priceless ability of the good cruising yacht – she could effortlessly maintain a respectable average speed over many miles while sailing the high seas in comfort.

Built in straightforward style of pitchpine planking on oak, Ainmara was highly regarded, and though the world was at war for four of the ten years John Kearney owned her, when he could sail his preferred cruising ground was Scotland. She was no slouch on the race course either. Her skipper became a member of Howth Sailing Club in 1920, and HSC's annual Lambay Race became a Kearney speciality, his first recorded overall win being in 1921 when, in a breezy race, Ainmara won the cruisers by one-and-a-half minutes.

Despite the turmoils of Ireland's War of Independence and Civil War, in the early 1920s John Kearney's position with the Port & Docks had become so secure that in 1923 he felt sufficiently confident to sell Ainmara in order to clear the way to build himself a new boat, the superb 38ft yawl Mavis, which was launched in July 1925. He was to own, cruise and race her with great success for nearly thirty years, by which time he was a pillar of the Dun Laoghaire sailing establishment – he'd a house in Monkstown, and had become Rear Commodore of the National Yacht Club, a position he held until his death in 1967.

Even with the demands of his work, and the continuing attention needed to run a yacht of the calibre of Mavis, he had found the time to design and sometimes also build other yachts of many types. What he didn't seem to have time for was simple domesticity. In later years his presence was enough to command respect, but in his vigorous younger days he could be waspish, to say the least, and a brief attempt at marriage was not a success.

Sibling relationships were also sometimes tense. Two of his brothers were boatbuilders and one of them, Jem, was almost always daggers-drawn with John. And Jem Kearney had regular battles with others, too. He was a classic Dublin character, and no stranger to salmon netting on the Liffey in circumstances of questionable legality. If one of these expeditions had been spectacularly successful, he would erupt triumphantly back into his family's little house on the East Wall Road and announce: "Pack you bags, Mrs Kearney, we're off to stay in the Gresham!" And he meant it, too. Mr & Mrs Jem Kearney of the East Wall Road became resident in the Gresham Hotel until the salmon money ran out.

So when he was building Mavis, John Kearney would only work with his brother Tom, and they were a fantastic team. But even that didn't last. One November night, working away at planking the hull, they took a break for a mug of tea at 9.30pm, and couldn't find the sugar. Each blamed the other for its absence. The row was seismic. The following night, each turned up with his own personal supply of tea, milk and sugar. And the work continued as smoothly as ever. But not one single word was exchanged between the two brothers for the remaining eight months of the project. It was years before they spoke again.

Quite what this meant when Mavis launched herself on St Stephens Day 1924 we can only guess. Like Ainmara eleven years earlier, Mavis could only be accommodated in Murphy's shed by being built in a large trench, and an exceptional Spring tide on December 26th 1924 saw her unplanned flotation. There was no damage done, but history doesn't record whether it was John and Tom who sorted the problem together despite not saying a word.

The immaculate Mavis made an immediate and successful impact, and Skipper Kearney and his beloved gaff yawl were honoured guests at regattas all along the east coast. While continuing to work full time for the Port & Docks, he kept up the spare-time yacht-building, but after the experiences with Mavis, when a regular Kearney crewmember, Billy Blood-Smyth, commissisoned a new 35ft gaff yawl from the skipper, it was client and designer who had to work together in the familiar corner of Murphy's yard to build the boat which became Sonia, launched in 1929.

Irish sailing was in a very quiet phase through the 1930s. Just about the only expanding organization was the Irish Cruising Club, and naturally John B Kearney and Mavis were on the first membership list in 1930, with Mavis a regular competitor in its offshore races, with a notable victory in the stormy 1935 race to the Isle of Man, a performance which won special praise from another participant, Humphrey Barton who was to found the Ocean Cruising Club 19 years later.

Mavis coming into port after winning the Clyde Cruising Club's annual Tobermory Race in 1938. Club rules at the time stipulated that as proper cruising yachts, the competing boats should tow their tenders throughout this race. Much effort went into designing sweet-lined dinghies.

Mavis also was overall winner of the Clyde Cruising Club's Tobermory Race in 1938. But while his own sailing was going splendidly, John Kearney was concerned at the sluggish state of sailing development in Ireland. In order to give younger people an opportunity to own their own boat, in 1932 he created the design for the 17ft Mermaid, a large clinker-built sailing dinghy which was designed to be constructed for around £180 - roughly the same price as a motorbike. The Mermaid was adopted by Dublin Bay SC, but it took a long time to gain momentum, and it wasn't until the late 1940s and early 1950s that it became the most popular class in the greater Dublin area. It is still active today with nearly 200 boats built, and more than 40 took part in its 80th Anniversary championship last summer in Skerries, the winner being Jonathan O'Rourke from the National YC,while the furthest travelled was Patrick Boardman's Thumbalina from Rush, which had started from Foynes on the Shannon Estuary, home to the most distant Mermaid fleet, and had – most impressively - sailed all the way round the south coast to Skerries to mark the 80th birthday.

The Mermaid was designed in 1932 to be built at the same price as the average motor-bike

With his retirement in 1944, John Kearney's design work came centre stage, and he was busy to the end, creating more than 20 cruising yachts in all. And life in Monkstown was pleasant. Over the door of the room where he did his design work, he'd a little motto on a brass plate: "God gives us our relatives. Thank God we can choose our friends". His close friends were all from sailing, and it was a crew member who had joined Mavis in 1946, the formidable Miss Douglas, who became his friend and housekeeper and looked after him to the end of his long and remarkable life.

John Kearney's entire life is in its way a great legacy, and his fine boats are his tangible memorials. They've ventured to the far corners of the world. For instance, the 30ft Evora, a lovely Bermudan yawl which he designed for building by Skinner's of Baltimore in 1936, was last reported from Darwin in Australia. The pretty Sonia of 1929 is well at home these days in British Columbia. And as for Mavis, the crème de la crème, she is currently undergoing a painstaking restoration in Maine by shipwright Ron Hawkins, who is very encouraged by the amount of original material he is able to retain.

John Kearney's first proper yacht, the 9-tonner Ainmara from 1912, has been owned for 47 years by former Round Ireland record holder Dickie Gomes of Strangford Lough. Last year, she celebrated her Centenary with a cruise to the Outer Hebrides. This year - next week in fact - she hopes to be in Dublin Bay for the Old Gaffers Association Golden Jubilee. And as it will be at Poolbeg Yacht & Boat Club, Ainmara will be back home in Ringsend for the first time in 90 years, and John Breslin Kearney will be well remembered, and celebrated too.

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.
