The saga of Thor Gitta's prolonged stay in Galway to load two former Aran Islands ferries bound for Mauritius, culminated with the cargoship's departure this morning, writes Jehan Ashmore.
Due to a series of incidents, mishaps and delays the Thor Gitta has been at the centre of attention. Crowds of Galwegians witnessed the loading of both ferries during the past week.

First to be loaded was the Clann na nOileáin on Wednesday in an operation than took four-hours while on Friday her sister Clann Eagle I took six-hours to be winched safely onto the cargo-deck during freshening winds.

It is ironic that since Thor Gitta 's arrival to the port's Dún Aengus Dock on 5 April that it would also nearly be the same time taken for the estimated 25-day delivery voyage of the ferries to the Indian Ocean island.

During the 8,300 mile journey Thor Gitta will make several port of calls with the first call to La Rochelle. The Bay of Biscay port is the next largest port south of Les Sables d'Olonnes, where the fast-ferries where built at the OCEA boatyard for her original owners Bád Arann Teoranta which traded as Aran Direct on routes from Rossaveal to the islands.

Thor Gitta was built in 1996 and is also designed to carry 364 TEU (twenty-foot equivilant unit) containers and belongs to an-eight strong fleet operated by the Danish company, Thor Rederi A/S of Svendborg.

One of the reasons why the heavylift vessel was delayed in loading was to ensure the correct positioning of the ferries so not to further disrupt other port call cargo allocation while on the long repositioning voyage to Mauritius.

The 4,078 tonnes cargsoship is also scheduled to make en-route calls to Pointe Noir in the Congo, Cape Town and Pemba in Mozambique before finally reaching the southern Indian Ocean destination.

When the ferries were completed in 2005 and 2006 they were valued between €5-6m but they only served up to September 2008 when the 243 passenger aluminium built craft were laid-up at the Connemara harbour due to financial difficulities.

This led to the company going into receivership and the vessels were put up for auction in Galway last February. Despite bids reaching €950,000, they were withdrawn at the auction hosted by the Cork based auctioneer, Dominic J. Daly.

In the following month the fast-ferries were sold to the French owner for a new career based from the island state which is in the Mascarene Islands. Mauritius is neighboured by the smaller islands of Agalega, Cargados Carajos, Rodrigues and the French island of Réunion some 200km to the southwest.

The loading of the second former Aran Island ferry, Clann Eagle I onto the cargoship Thor Gitta in Galway has finally been completed today, writes Jehan Ashmore.
The 4,078 tonnes vessel is scheduled to depart the mid-western port tomorrow evening on the 8,300 mile delivery voyage to Mauritius.

Despite freshening winds the 169 gross registered tonnes ferry was winched out of the waters of the port's Dún Aengus Dock. In total the operation took six-hours which saw the delicate positioning of the 27m long ferry between the ship's two deck-mounted cranes and lowered onto the cargo-deck.

Yesterday proceedings to load the ferry were suspended due to delays in relocating other cargo so to accommodate the 243 passenger capacity ferry. This followed the loading of her sister Clann na nOileáin on Wednesday.

Several previous attempts to hoist the Clann Eagle I onto the deck of the Danish-flagged vessel have been hampered. At one stage due to complications in efforts to transport the vessels, the 100m Thor Gitta was temporary detained by the admiralty marshal.

Procedures to load the 29 knots fast-ferry pair have been beset with incidents notably the grounding and subsequent damage to the first chartered cargoship, Patanal, off Rossaveal. It was originally planned to sail the ferries out into Casla Bay where the German-flagged vessel would load them onboard.

As a consequence the ferries were transferred to Galway where the Clann na nOileáin did not escape attention either. On the first attempt to load the ferry one of the ship's slings snapped from the crane-cradle causing the 172 tonnes ferry to fall into the water.

Minor damage was caused to the ferry, though three men who remained onboard at the time of the incident were taken to hospital but were later released.

Last month the ferries were sold to a French buyer after the company that owned them Bád Arann Teoranta (trading as Aran Direct) went into receivership. The ferries operated on several routes between Rossaveal to the islands but are now destined to serve on an inter-island service from the Indian Ocean island.

Published in Ports & Shipping
In the process to load two fast-ferries onboard a heavy-cargo liftship in Galway port the operation has taken on yet another setback, writes Jehan Ashmore.

Despite successfully loading the first ferry, the 172 gross tonnes ferry Clann na nOileain yesterday morning, which took four hours, the time to secure the vessel on the cargoship's deck continued much longer than anticipted.

As a consequence this led to further delays in the the clearance of existing cargo so to enable sufficient space to load the second ferry onboard the Thor Gitta.

THOR_GITTA

The 4,078 gross tonnes heavy-cargo liftship was due to have started loading the second ferry the 169 tonnes ferry Clann Eagle I yesterday afternoon but this has been delayed until 12 noon today.

The Danish-flagged Thor Gitta has been in Galway for over a fortnight. She berthed with her starboard side facing alongside the quay. With this orientation the cargoship's two-deck mounted cranes swing out on the opposite port side which were used to raise the first ferry out of the water on 7 April.

On that ocasion the forward sling snapped causing the Clann na nOileain to plunge into the waters within the port's single dock named the Dun Aengus Dock.

In recent daysThor Gitta has shifted berths which has resulted in the 100m long vessel berthing on her starboard side again next to the dock's quayside. The deck-mounted cranes on the port side continue to face out overlooking the open water of the dock.

The loading of Clann na nOileain is all the more skillfull considering that the 27m length of the ferry had to be hoisted and swung at an angle between the narrow span of the two deck mounted cranes.

For file photos of vessels in loading mode from the Rederi A/S fleet owners of the Thor Gitta click here.

Thor Gitta is the second chartered vessel called in to assist in the transportation of the two former Aran Islands fast-ferries.

The other cargoship, the longer 120 metre Patanal, ran aground at the end of March during stormy seas after dragging its anchor in Casla Bay, at the entrance to Rossaveal harbour. The 7,002 tonnes vessel sought initial repairs before leaving Galway Bay last week for further work in Germany.

The monuhull fast ferry pair were custom built in France for Bad Teoranta (trading as Aran Direct) but the company went into recievership.

At an auction held in Galway last month the vessels did not sale despite bids reaching €950,000, they were withdrawn at the auction. The ferries were later sold for a sum believed to be seven-figures to an operator based in the Indian Ocean island of Mauritius.

In a third attempt to load two fast-ferries bound for Mauritius, one of the vessel's has so far been successfully positioned onboard the cargoship in Galway dock, writes Jehan Ashmore.

The Clann na nOileáin was first loaded onboard this morning whereas her sister Clann Eagle I will be hoisted this afterrnoon. It is expected that this procedure will take around four hours to complete.

The 234-passenger ferries have been the centre of attention since two previous attempts proved unsuccessful following incidents in the mid-west port.

On the first attempt that took place nearly a fortnight ago, three men onboard the ferry were injured when the ships's crane-sling snapped when handling the 170 tonnes ferry Clann na nOileáin.

Fortunately the ferry was hanging over the water and splashed into Dun Aengus Dock rather than landing on the hold of the 4,078 gross tonnes cargo-vessel Thor Gitta. In the second attempt last
Saturday one of the cargoship's cranes sounded a safety alarm which halted proceedings.

The Danish-flagged Thor Gitta is the second heavy-lift cargoship that has been called in to assist in transporting the two former Aran Islands fast-ferries. The 100m cargoship is owned by Thor Rederi A/S of Svendborg and is expected to depart Galway tommorrow morning.

The first heavylift vessel the German-flagged Patanal grounded in rough seas after dragging its anchor in Casla Bay at the entrance to Rossaveal, where the ferries were originally based in readiness for loading.

Patanal suffered hull damage and was taken into Galway Bay for preliminary repair work. Last week the 7,002grt vessel operated by Harren + Partners, departed the bay to undergo further repairs at a dry-dock in Bremerhaven.

In a third attempt to load two former Aran Islands ferries at Galway yesterday, operations took on a new twist as the cargoship chartered in to transport them was detained according to a report in todays Irish Times.
The Thor Gitta, a 4078 tonnes heavy lift cargoship was held at the port's Dun Aengus Dock as new complications arose in an effort to transport the two passenger fast-ferries Clann na nOileáin and Clann Eagle 1 which are bound for Mauritius in the Indian Ocean.

Harbourmaster Capt. Brian Sheridan, confirmed yesterday evening that the Danish flagged vessel had been detained at lunchtime on the instructions of the admiralty marshal, a High Court judge, acting under maritime law. Until matters are resolved, a ship's keeper has been placed onboard by the Revenue Commissioners.

Published in Ports & Shipping
The heavy lift cargoship Thor Gitta is due to make a second attempt to load two former Aran Islands fast ferries in Galway Docks tomorrow morning, writes Jehan Ashmore.
It is envisaged that the operation to hoist the sisters, Clann Eagle I and Clann na nOileáin which each weigh 170 tonnes will be completed by tomorrow evening. The Danish flagged heavy liftship is expected to remain in port until Friday so as to make further preparations in advance of the long delivery voyage to the ferries new owners in Mauritius in the Indian Ocean.

In the first attempt to load the ferries last week, the Clann na nOileáin fell into the Dun Aengus Dock when the sling rope broke causing the French built 234-passenger craft to fall some 12m /40ft. Onboard the ferry were three people who were taken to hospital but were later released.

Thor Gitta is fitted with two deck-mounted cranes and this feature is also similarly found on the Patanal, which grounded in Casla Bay at the entrance to Rossaveal, nearly a fortnight ago. The German owned 7,002grt was the first vessel chartered to bring the fast-ferries from Rossaveal, but the ferries were subsequently sailed to Galway after the ship was refloated.

The 120m Patanal has undergone "underwater and internal inspections and repairs," according to Capt. Brian Sheridan, harbourmaster of Galway Port Company though he added "that the vessel would remain subject to an inspection by the Marine Survey Office before she can be released".

According to a statement released by the Patanal's owners, Harren & Partner, the vessel is then to be taken to dry dock in Bremerhaven for further repairs.

Since the incident the vessel has been at anchorage off Black Point on the Co. Clare side of Galway Bay where she was monitored initially for pollution and the tug Celtic Isle in attendance. The tug is operated by Celtic Tugs and is normally based in Foynes, Co. Limerick.

A 7,837 tonnes heavy cargo-liftship Pantanal which was to collect two former Aran Island fast ferries, ran aground this morning in rough seas off Rossaveal, according to RTE.ie
The Danish-owned vessel got into difficulties around 06.00 when it ran aground in Casla Bay at the entrance to the Connemara harbour. The Pantanal which has a crew of 14 are trying to establish it the 2004 built vessel can be refloated later today.

Pantanel which is equipped with two deck-mounted cranes was due to lift the 170 tonnes fast ferry sisters Clann Eagle I and Clann na nOileáin. The pair which were owned by Bád Arann Teo (trading as Aran Direct) went into receivership and were sold last month to new owners in Mauritius in the Indian Ocean. For further details click  here.

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.
