The Barrow Navigation is a short stretch of canal that bypasses the rapids on the river Barrow. Though these are tagged "Kilkenny" from a sense of local patriotism, I should point out that we were riding on the Wexford side of the river.
Suppose the same aircraft is positioned at Point A as shown
at the bottom of Figure 3-1 and the pilot wishes to navigate
directly to Point C, which is neither a VOR station nor airway
intersection. This pilot has an even more difficult situation.
Assuming the VOR stations are within reception range, the
pilot needs to create two makeshift airways using a navigation
plotter and chart, fly to intercept one of them, then track
to Point C (which the pilot has defined as the intersection
between the two courses).
Newark, Nottinghamshire.
The River Trent Navigation - Newark Town Lock.
Over 90ft long and 32ft wide,
this lock was constructed in 1952 to
accommodate four barges at a time. At
the time of construction, numerous
petrol tanker barges regularly passed
through to discharge their loads at
Colwick. In the 1960s a pipeline grid for
the transport of oil took over this role
and the traffic in large barges virtually ceased.
The River Trent and its Devon tributary
have played an important role in Newark’s
life for many centuries. Before highways,
canals, railways and finally motor transport
were established, the rivers were the only
practical means to transport large and
heavy goods over long distances; rivers also
provided access to the sea for international
trade. Newark was built at the lowest
fording point on the Trent, which was
eventually protected by the castle and then
bridged, so it was natural that it should
become a centre for river-borne
commerce, particularly trading in wool.
The river banks hosted a thriving inland
port with wharves, warehouses, mills,
maltings and breweries bringing people,
employment and wealth to the town.
Weybridge is a town in the Elmbridge district of Surrey in South East England. It is bounded to the north by the River Thames at the mouth of the River Wey, from which it gets its name.

Taken on an excursion cruise on the paddle steamer Waverley, travelling from Westminster to Gravesend to Southend, into the Medway and back again.
Waverley is named after Sir Walter Scott’s Waverley novels. She was built to replace the 1899 Waverley which was sunk by enemy action on May 29, 1940 at Dunkirk.
Waverley’s keel was laid on December 27, 1945 but due to material shortages after the war, she was not ready for launch until October 2, 1946. It wasn’t until the following year on January 20, 1947 that she was towed to Greenock for the installation of her boiler and engines. Her maiden voyage was on June 16, 1947.
Waverley was built for the route up Loch Goil and Loch Long from Craigendoran & Arrochar in West Scotland. She now visits several areas of the UK offering regular trips on the Clyde, The Western Isles, the Thames, South Coast of England and the Bristol Channel with calls at Liverpool & Llandudno.
Waverley is the World’s last seagoing paddle steamer. In 1974, at the end of her working life, she was famously gifted for £1 to the Paddle Steamer Preservation Society. Waverley Steam Navigation Co. Ltd., a charity registered in Scotland, was set up to own and operate the ship. Waverley then began a second career as one of the country’s best-loved tourist attractions. Since she has been in operational preservation, she has been awarded four stars by Visit Scotland, an engineering heritage award, and has carried over 6 million passengers from over 60 ports around the UK.
2003 saw the completion of a £7m Heritage Rebuild which returned Waverley to the original 1940s style in which she was built. This was made possible with major grants from the Heritage Lottery Fund and the Paddle Steamer Preservation Society (PSPS). Contributions also came from Glasgow City Council, Scottish Enterprise Glasgow, the European Regional Development Fund and local authorities.
In May 2019 Waverley was withdrawn from service and a capital appeal was launched to raise £2.3 million to allow her boilers to be replaced and re-commission Waverley for further service. In December 2019 it was announced that the appeal target had been reached.
Despite delays to the boiler refit due to the COVID-19 pandemic Waverley returned to service in August 2020 and operated a short season on the Firth of Clyde. After a successful season on the Clyde the following year, Waverley will be returning to other sailing areas in 2022.
2022 marked 75 years since Waverley’s maiden voyage on June 16, 1947.
Paddle steamer history
In 1812, when Henry Bell’s paddle steamer Comet became the world’s first commercial steamship to operate in coastal waters, a tradition was started which remains alive today only in the form of the world’s last seagoing paddle steamer, Waverley.
From the 1860’s onward, paddle steamers developed an important niche in the coastal passenger and excursion trade. Large fleets served the cities, towns, villages and resorts of the Firth of Clyde, the Bristol Channel, the South Coast of England, London and the Thames Estuary.
Paddle Steamers also made a significant contribution to the war effort as minesweepers in both World Wars, and indeed Waverley is named after and was built to replace the previous Waverley who performed a heroic role at Dunkirk in May 1940 before being sunk by enemy action.
With a few exceptions, the Clyde steamers were owned and operated by railway companies. These were largely commuter ferries linking all the villages with the nearest railhead for onward travel.

Rochdale Canal, Manchester.
At Lock 84. Dale Street Lock.
The first in the series of 9 locks on the extension linking the former Rochdale Canal basin at Dale Street with the Bridgewater Canal basin at Castlefield, all in working order.
The lock of 1804-05 is Grade ll listed.
Looking towards Ancoats.
The Rochdale Canal runs for 33 miles between Manchester and Sowerby Bridge in West Yorkshire. In Sowerby Bridge it connects with the Calder and Hebble Navigation. In Manchester it connects with the Ashton and Bridgewater Canals.
The canal opened through to Manchester in 1804. This made it the first trans-Pennine canal route. It remained profitable for some time but by the 20th century the tonnage being carried was in sharp decline. In 1937 the last boat made the through journey across the Pennines on the Rochdale Canal.
In 1952, the canal was closed apart from the short section between Castlefield and the Ashton Canal junction at Piccadilly. The Ashton was abandoned in 1962 and by 1965 the nine locks on the Rochdale through Manchester city centre were almost unusable. Enthusiastic supporters re-opened the Ashton in 1974 and the Rochdale Canal in Manchester was made good.
The Rochdale Canal Society was formed to promote the restoration of the canal and in the 1980s and 1990s small scale work began to re-open stretches of the canal between Todmorden and Sowerby Bridge. This involved restoring bridges and locks to navigable condition.
The most major project was the construction of the new Tuel Lane lock and tunnel in Sowerby Bridge. The lock replaced two locks in an infilled section and, with a fall of almost 20 feet, is the deepest lock on the inland waterways system. In 1996 the canal was opened to navigation once again between Sowerby Bridge and the summit level.
The canal was re-opened to navigation along its entire length in July 2002 and forms part of the South Pennine Ring.
