Good navigation is of the utmost importance in the Lake District – which is why we took the bears with us. Sedgie (left) and Armitage have enviable skills in that area, so we always felt safe with them. Our trust was well rewarded, too: never once did we get lost, thanks to the bears' ineffable skills.

The Gantocks is a small group of rocks, lying off Dunoon in the upper Firth of Clyde, West of Scotland.
A navigation beacon was constructed on the rocks circa 1886. The beacon is 44 feet in height.
The Chart, Protractor and the circular slide rule side of a "Whizz Wheel" shown here are the very old school tools of the trade of aircraft navigators.
These day it is all done on a laptop or tablet but I like to teach the old school ways of doing it as it encourages a proper understanding of what is happening when planning a flight

Worcester Bar Footbridge at Gas Street Basin the junction point of the Birmingham Main Line Canal and the Worcester and Birmingham Canal in Westside, Birmingham, West Midlands.
The Birmingham Canal, completed in 1773, terminated at Old Wharf beyond Bridge Street. When the Worcester and Birmingham Company started their canal at a point later known as Gas Street Basin the Birmingham Canal Navigations Company (BCN) insisted on a physical barrier to prevent the Worcester and Birmingham Canal from benefiting from their water. The Worcester Bar, a 7 ft. 3 in. wide straight barrier 84 yards long was built perpendicular to the run of the two canals. Cargoes had to be laboriously manhandled between boats on either side.
The Worcester and Birmingham Canal opened between Birmingham and Selly Oak on 30 October 1795 but took until 1815 to complete to Worcester, at which time, after much lobbying by iron and coal masters and the Worcester and Birmingham Canal Company, an Act of Parliament was passed to open up the bar and the bar lock was built. There were toll offices either side of the bar lock and tolls were collected by each company from boats using the canals. The Worcester Bar still exists, with boats moored to both sides of it. It is connected to Gas Street via a footbridge reconstructed to a design by Horseley Ironworks of the 19th century.
During the 1990s much of the area around the basin was redeveloped and older buildings refurbished.
Looking out from Hebden Bridge Wharf Footbridge down the Rochdale Canal in Hebden Bridge, Calderdale, West Yorkshire.
The Rochdale is a broad canal because its locks are wide enough to allow vessels of 14 feet width. The canal runs for 32 miles (51 km) across the Pennines from the Bridgewater Canal at Castlefield Basin in Manchester to join the Calder and Hebble Navigation at Sowerby Bridge in West Yorkshire. As built, the canal had 92 locks. Whilst the traditional lock numbering has been retained on all restored locks, and on the relocated locks, the canal now has 91. Locks 3 and 4 have been replaced with a single deep lock, Tuel Lane Lock, which is numbered 3/4.
The Rochdale Canal was conceived in 1776, when a group of 48 men from Rochdale raised £237 and commissioned James Brindley to conduct a survey of possible routes between Sowerby Bridge and Manchester. Brindley proposed a route similar to the one built, and another more expensive route via Bury. Further progress was not made until 1791, when John Rennie was asked to make a new survey in June, and two months later to make surveys for branches to Rochdale, Oldham and to a limeworks near Todmorden. Rennie at the time had no experience of building canals.
The promoters, unsure as to whether to build a wide or a narrow canal, postponed the decision until an Act of Parliament had been obtained. The first attempt to obtain an act was made in 1792, but was opposed by mill owners, concerned about water supply. Rennie proposed using steam pumping engines, three in Yorkshire, eight in Lancashire, and one on the Burnley Branch, but the mill owners argued that 59 mills would be affected by the scheme, resulting in unemployment, and the bill was defeated. In September 1792, William Crosley and John Longbotham surveyed the area in an attempt to find locations for reservoirs which would not affect water supplies to the mills. A second bill was presented to Parliament, for a canal which would have a 3,000-yard (2,700 m) tunnel and 11 reservoirs. Again the bill was defeated, this time by one vote. The promoters, in an attempt to understand the mill owners' position, asked William Jessop to survey the parts of the proposed canal that were causing most concern. Jessop gave evidence to the Parliamentary committee, and on 4 April 1794 an act was obtained which created the Rochdale Canal Company and authorised construction.
Rennie's estimated cost in the second bill was £291,000, and the company was empowered to raise the money by issuing shares, with powers to raise a further £100,000 if required. The estimate was for a narrow canal, whereas the act authorised a broad canal, and so the capital was never going to be adequate. The summit tunnel was abandoned in favour of 14 additional locks saving £20,000. Jessop proposed constructing each lock with a drop of 10 feet (3.0 m), resulting in efficient use of water and the need to manufacture only one size of lock gate.
The canal opened in stages as sections were completed, with the Rochdale Branch the first in 1798 and further sections in 1799. The bottom nine locks opened in 1800 and boats using the Ashton Canal could reach Manchester. Officially, the canal opened in 1804, but construction work continued for more three years. A 1.5-mile (2.4 km) branch from Heywood to Castleton opened in 1834.
Apart from a short profitable section in Manchester linking the Bridgewater and Ashton Canals, most of the length was closed in 1952 when an act of parliament was obtained to ban public navigation. The last complete journey had taken place in 1937, and by the mid 1960s the remainder was almost unusable. Construction of the M62 motorway in the late 1960s took no account of the canal, cutting it in two.
When an Act of Parliament was sought in 1965, to authorise the abandonment of the canal, the Inland Waterways Association petitioned against it, and when it was finally passed, it contained a clause that ensured the owners would maintain it until the adjacent Ashton Canal was abandoned. Discussion of the relative merits of restoring the canal or the Huddersfield Narrow Canal in 1973 led the formation of societies to promote both schemes in 1974. The Rochdale Canal Society wanted to see the canal fully re-opened, as part of a proposed Pennine Park
The Rochdale Canal Society worked hard both to protect the line of the canal and to begin the process of refurbishing it. A new organisational structure was created in 1984, with the formation of the Rochdale Canal Trust Ltd, who leased the canal from the owning company. The MSC-funded restoration was approaching Sowerby Bridge, where planners were proposing a tunnel and deep lock to negotiate a difficult road junction at Tuel Lane, so that a connection could be made with the Calder and Hebble Navigation. The entire eastern section from Sowerby Bridge to the summit at Longlees was open by 1990, although it remained isolated from the canal network.
In 1997, the Rochdale Canal Trust was restructured, in response to announcements that there might be large grants available as part of the millennium celebrations. The canal was still at this point owned by a private company, and the Millennium Commission would not make grants to a scheme which was for private profit, rather than public benefit. The restructuring would allow the Trust to take over responsibility for the canal from the Rochdale Canal Company. However, the plan was rejected by the Commission, and in order to access the grant of £11.3 million, the Waterways Trust took over ownership of the canal. As restoration proceeded, boats could travel further and further west, and the restoration of the sections through Failsworth and Ancoats were a significant part of the re-development of the north Manchester districts. The restored sections joined up with the section in Manchester below the Ashton Canal junction, which had never been closed, and on 1 July 2002 the canal was open for navigation along its entire length.
