Cormac McHenry 1936-2023

Cormac McHenry of Dun Laoghaire, who died on December 22nd at the age of 87, was a highly-regarded sailing enthusiast with a particular interest in short-handed long-distance cruising, a quietly determined enthusiast who had many other interests including Leinster rugby, all of which he pursued with the same devoted, serious and intelligent focus that he brought to the world of boats.

His boyhood as the oldest of four children was in Dublin in Rathgar and Terenure, and he acquired his lifelong love of rugby in Terenure College. But by the time he was taking Electrical Engineering in University College Dublin, he was into motor-cycling and car rallying, a speciality in the latter being as a navigator.

Initially developing his career in the corporate world as an engineer after further training with General Electric in England, he went on to several postings in Ireland with major companies. This involved a peripatetic lifestyle for his already expanding young family, for in UCD he’d taken the first steps towards a long and happy marriage of 67 years to Barbara Nevin, the daughter of the UCD Professor of Physics.

STARTING WITH SELF-BUILD ENTERPRISE DINGHY

They’d five daughters whose earliest childhood memories include an early period of living near Drogheda in County Louth, while their busy father - having worked through his fascination with high speed cars to the conclusion it was dangerously inappropriate for a young husband with a growing family - was to build himself an Enterprise dinghy to develop his interest in sailing, initially with the Boyne Yacht Club at Mornington.

This was taken a stage higher with an aspiration to the Olympic ideal with an International Finn, which seemed to the children to involve complex family holidays featuring long and dusty driving with the heavy boat in the car roof down the sometimes rudimentary Spanish and Portuguese roads of those days, in order to reach some major Finn regatta venue, representing Ireland at places like Cascais.

However, by the time he took up a position in Waterford his interest in sailing had developed into what became his lifelong enthusiasm for cruising and voyaging, and in due course he launched his 6-ton Kerry Class cruiser Ring of Kerry for the first time, lowering her gently into the river for the first time afloat in the heart of Waterford.

SELF-COMPLETED KERRY CLASS

He’d finished the boat himself from a bare hull to a notably high standard with skills developed with both the Enterprise and the Finn and other DIY projects which gave him special satisfaction. But while he was to make many longtime sailing friends in Waterford sailing’s focal point in Dunmore East with WHSC, a further career change of direction brought him back to Dublin, where in time Barbara reinforced her links to UCD administration by becoming the Examinations Officer for every branch of that expanding university.

The extensively-voyaged Kerry Class 6-tonner Ring of Kerry was completed by Cormac from a bare hull, and her first sailing was with Waterford Harbour SC at Dunmore East. She is seen here at an ICC Rally in Port Dinorwic on the Menai Straits in North Wales.

Cormac in turn had found his real and spiritual nautical home in the National Yacht Club, which he joined in 1967. From the very beginning of his 56 years of membership, he found the National to be congenial, so much so that his daughter Susan Spain – currently the NYC Honorary Sailing Secretary – said in her Eulogy at his very well-attended funeral on December 27th that the NYC is now in the McHenry DNA, something reflected in the fact that in his mature years, Cormac served for a long time as a National YC Trustee.

His long career - both ashore and afloat – had taken the ideal course to achieve that highly-respected position in club administration. In professional life, despite his engineering qualifications his particular interest developed in labour relations and the resolution of workplace disputes, and by the time he retired, he had become a much-respected Member of the Labour Court, a satisfying involvement in a key area of Irish life that had come about with a fresh career change in the mid 1980s.

SAIL TRAINING IDEAL

Meanwhile, in developing his sailing experiences, he was naturally drawn to the sail training ideal, and was one of the few in the Irish maritime community in recent years who could still look back to a long interaction with Coiste an Asgard, first with the original Asgard in her sail training role from 1968, then with her successor the ketch Creidne which is now with the Naval Service Yacht Squadron in Haulbowline on Cork Harbour, and most rewardingly with the 84ft Sail Training Brigantine Asgard II from 1981 onwards.

However, despite his active involvement with other sailors and their boats, he was always determined to have one of his own, and thus completing Ring of Kerry had been satisfying in many ways, not least in its opportunities for technical and philosophical exchanges with the boat’s designer O’Brien Kennedy MRINA, whose seagoing experience was reflected in his membership of the Irish Cruising Club, an organisation to which Cormac himself was to be elected in 1980, with Barbara joining in 1993.

In his 43 years of membership of the ICC, he cruised extensively firstly in Ring of Kerry, then the Nicholson 31 Erquy (named for the Breton port in which he and Barbara has spent their honeymoon), and finally in the remarkably comfortable American-designed and built Island Packet 40, whose name of Island Life reflected Cormac’s sense of self-reliance afloat, while also providing the perfect boat for his later years, when he and Barbara spent several seasons based at Portosin on northwest Spain’s Galician coast.

His many years of cruising of every kind brought a return to his fellow enthusiasts, for during his 43 years of membership of the Irish Cruising Club, he gave unstintingly of his time in voluntary roles for a continuous 17 of those years, starting as a Committee Member and then going on to become the Honorary Secretary from 1990 to 2003, the Rear Commodore in 2003-2004, then Vice Commodore in 2003-2004, and finally Commodore in 2004-2005.

Additionally, he served as standby Editor of the ICC Annual if the official Editor happened to be away in an extended cruise, and in all his roles, his fastidious attention to detail and the procedurally correct made a major contribution to the Irish Cruising Club’s ability to take on its growing status in the international cruising and voyaging world.

This in turn saw his own international cruising club memberships and friendships expanding. He joined the Ocean Cruising Club in 1990, and was elected to the 1880-founded Royal Cruising Club in 1999, while his significant positions in the ICC saw friendships develop with both the Clyde Cruising Club and the Cruising Club of America.

INTENSELY PERSONAL VOYAGING

But all this was the outward manifestation of a friendly and helpful yet very private person, whose own special interest continued to develop in his own intensely personal voyaging. This initially was undertaken in the pre-GPS area, when he derived much satisfaction from using his own skills in celestial navigation to arrive precisely on target at the conclusion of his first ocean passage, from Ireland to the Azores single-handed in the little Ring of Kerry in 1989. This venture had become such a satisfyingly complete cruise on his return that he was awarded the Irish Cruising Club’s premier trophy, the Faulkner Cup.

He was to go on to receive the Faulkner Cup again in 1997, for a solo Atlantic Circuit cruise with the Nicholson 31 Erquy, but his cruising by this stage was so frequent and extensive that at various stages he had been awarded the ICC’s Strangford Cup for an alternative best cruise in 1996 and the Atlantic Trophy in the same year, while earlier - to underline his deeply-felt interest in all things Irish - he was awarded the Round Ireland Cup with Erquy in 1995.

Ocean voyaging continued with the acquisition of Island Packet, and like many more senior Irish cruising folk, he and Barbara were drawn to the attractions of northwest Spain, with his final cruising years being happily spent there with Island Life.

However, back home the new generation was coming along in Dun Laoghaire sailing with his daughter Susan - now Susan Spain – moving through the ranks of National YC administration to become the Honorary Sailing Secretary of the Club. She has done this in such a clearly defined personal way that not all the club’s large membership were aware that she was the daughter of their long-serving Trustee, Cormac McHenry.

REMEMBERED WITH THE DUBLIN BAY WATER WAGS

But this relationship was demonstrated in a very Dun Laoghaire style when Susan commissioned and launched her new Dublin Bay Water Wag at the NYC last September. Classically built by master craftsman Rui Ferreira of Ballydehob in West Cork, this latest manifestation of a local class dating back to 1887 was to be named Cormac, and it was the man himself who made one of his last appearances when asked to perform the naming ceremony in traditional style.

Typically, in his special appreciation of the workmanship involved, Cormac flatly refused to smash the bottle over the stemhead. Instead, he poured some of the champagne with gentle and loving care over a small area of the immaculate varnishwork, leaving everyone with an abiding final memory of a great sailor and assiduous servant of sailing, a skilled technician and craftsman who, when asked, was always generous with practical and sound advice, particularly when it was something to do with boats and sailing and the people who go with them.

Cormac McHenry RIP

Afloat.ie regrets to record the death of Cormac McHenry, for many years a leading figure in the Irish Cruising Club. He also served as a Trustee and was a Life Member of the National Yacht Club in Dun Laoghaire.

An enthusiastic long-distance sailor and member of the Ocean Cruising Club, he made several ocean passages, a number of them single-handed.

A fuller appreciation of Cormac and his wide involvement in many areas of sailing in Ireland will appear in Afloat.ie in due course.

Meanwhile, our heartfelt condolences are with Barbara, his wife of 67 years, and his family and many friends in sailing and his other interests.

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.
