54-529: A Casey and Mobbs partnership, and a large number of prospectors worked in the surrounding hills. After a winter closure, the Ulvin hotel reopened in spring 1905. The gold boom over, the town quickly faded. During 1913–1915 and 1922, gold dredging operations took place on the river. The train made a one-hour meal stop at the Miners' Hotel into the 1920s. Emma Rear, step-daughter of John Ulvin, later operated

135-495: A river at right angles to the current, the ferry is, in sailing terminology, sailing on a reach with the true current exactly at right angles to the direction of crossing. For the anchored-tether type ferry this is valid when the tether is parallel to the current, near the middle of crossing. In sailing, the speed is governed by the lift-to-drag ratios (L/D) of the sail and the hull including centerboard or keel and rudder. For reaction ferries, L/D ratios also apply except that one

162-434: A rudder change the relative lengths of the bridle or multiple tethers in order to steer. The lateral force of the current moves the ferry across the river. A now rare type of reaction ferry uses a submerged cable lying on the bottom across a river or tidal water. This can be a wire rope or a chain and is pulled to the surface by the ferry or its operator. It passes through moveable pulleys or belaying points whose location sets

189-409: Is really a three-dimensional situation. R can be resolved in a drag component directly downstream and a component in the direction of crossing, the thrust T which drives the ferry. This is balanced by the opposing drag of the traveller pulleys. The amount of lift required is set by the angle of incidence of the ferry to the apparent current (here 10°), often done with a rudder (not shown). In the figure

216-786: Is reputed to have been designed by Leonardo da Vinci . A number of reaction ferries operate: Four passenger ferries cross the Rhine in Basel . Three such ferries cross the Aare in Bern . A small traditional ferry, the last on this river, crosses the Doubs . The Hampton Loade Ferry , which carried passengers only, crossed the River Severn at Hampton Loade in Shropshire until 2017. It

243-409: Is very high, for example typically 30 for a traveller on a steel rope, as visible in aerial photographs, and the other can vary from low, e.g. 1-2 without a centerboard, to 3.5 with one. A diagram is shown which follows the standard force diagram for sailing. It is drawn with a traveller L/D of only about 6 in order to make it clearer. The ferry L/D is drawn at 1.5. The lift L acts at right angles to

270-407: The reaction of the current of a river against a fixed tether to propel the vessel across the water. Such ferries operate faster and more effectively in rivers with strong currents. Some reaction ferries operate using an overhead cable suspended from towers anchored on either bank of the river at right angles to the current flow. A "traveller" with pulleys runs along this cable and is attached to

297-525: The Île Bizard . Reaction ferries cross the rivers Sava and Drava . A number of reaction ferries operate in Germany, particularly across the rivers Elbe and Weser . Between the 17th and 19th centuries, they were quite common on the Rhine . Currently operating ferries include: The Traghetto di Leonardo  [ it ] is a historic reaction ferry across the Adda River at Imbersago . It

324-488: The 1890s, the trail from Lardeau to Trout Lake joined the Lardeau River at Cascade Creek, just upstream from the future Gold Hill. Second Crossing was the original name, being the second place the railway crossed the river. In 1903, Edward Mobbs established a town during the goldrush, which he called Uto, but then renamed as Goldhill within days. Some early newspaper reports did not clearly differentiate between

351-537: The Ulvin Bros applied for a liquor licence that November, their Miners' Hotel may well have opened months later. Casey and Murphy opened the Hotel Bosworth in the new year, but the location could have been closer to Bosworth. In March 1904, Hawthorne Bros completed their store. During the brief 1904–1906 post office existence, Charles Hawthorne was postmaster. By summer 1904, the Hotel Bosworth had become

378-466: The crossing and Bosworth, which might suggest the commercial enterprises were found somewhere in between. During the railway construction, grading northwestward had reached Duncan City (Howser) by 1899, but clearing extended well beyond. At the second crossing, about 13 kilometres (8 mi) away, a ferry operated across the river. When the reaction ferry barge was launched for the season in June 1901,

405-443: The crossing speed is the same as the speed of the true current. With a centerboard or keel, the hull's L/D could increase several times. This would increase the crossing speed also several times, but according to the drag equation the forces increase with the square of the speed and put a great load particularly on the overhead cable. With the anchored-tether type ferry, such high speeds would be unobtainable because its tether drags in

432-408: The direction of the apparent current, the vector sum of the true current and the current component due to the crossing speed. The drag D acts parallel to the apparent current. The vector sum of L and D is the resultant force R. This force can only exist because the tether exerts an opposed force of the same magnitude (see Newton's laws of motion ), in this simplified two-dimensional projection of what

459-457: The ferry with a tether rope. This can divide into a two-part bridle which defines the angle of the ferry to the current. Sometimes two pulleys and tethers are used. Sometimes a single tether is attached to a bar that can be swung from one side of the ferry to the other. This type also uses a rudder in order to set the angle of the ferry to the current flow from zero - it is then stationary - to the best angle for maximal crossing speed. Ferries without

486-414: The ferry's angle. In order to set off, manual work is required to initially pull the cable and also to manoeuvre, especially during the turning of the tide. The ferry may consist of a single hull, or two pontoons with a deck bridging them. Some ferries carry only passengers, whilst others carry road vehicles, with some examples carrying up to 12 cars. A reaction ferry operates as a sailing craft where

513-520: The highway bridge underwent extensive repairs. It is unclear whether this was the former rail bridge and current highway bridge. The narrowed valley at this point provided a good location for a bridge. The northwestward advance of the Arrowhead and Kootenay Railway rail head reached Second Crossing in November 1901. That month, a temporary bridge was completed, to be replaced by a truss bridge in

540-424: The hotel. One account suggests closure in the 1940s and the later dismantling and removal of the building to Gerrard . Another account suggests the hotel was still operating into the 1950s. All the earlier buildings have since disappeared and only a few scattered later residences remain. In 1912, land was promoted for developing orchards. Reaction ferry A reaction ferry is a cable ferry that uses

567-479: The line and the rail bed was adapted to become a public highway. Both Edward Mobbs and Hugh McDonald applied for liquor licences in 1901, but only Joseph Howson, who ran the Ottawa House hotel, was granted one. Months later, he transferred the licence to McDonald. By summer 1903, a new mining camp held a large number of prospectors. At the time, the wagon road from Poplar Creek was upgraded. Although

621-438: The spring. That December, five construction crew sustained minor injuries when their handcar collided with a stationary flatcar just south of the crossing. After a break over the winter, tracklaying on this Canadian Pacific Railway (CP) subsidiary resumed the following May and was completed to the foot of Trout Lake in early June. During 1904, Gold Hill may also have been an unofficial flag stop . In 1942, CP abandoned

648-450: The traveller pulleys represent the wheels of a land yacht and the moving fluid is the water current rather than the wind. In the case of a reaction ferry with an anchored tether, the analogy can also be to a kite . In both cases the ferry's hull itself represents a sail and is angled to the apparent water current in order to generate lift in the same way a sail is set at an angle to the apparent wind . With an overhead cable stretched across

675-592: The water or is supported by buoys that do and this drag would also increase with the square of the speed. At one time over 30 reaction ferries crossed the rivers of British Columbia , primarily the Fraser River and the Thompson River . Those still operating include: In Quebec , the small Laval-sur-le-Lac–Île-Bizard Ferry operates seasonally across the Rivière des Prairies from Laval-sur-le-Lac to

702-413: The wild current took up the slack in the cable, creating a sudden jerk. The cable drum snapped off and two of the seven railway engineers on board were propelled overboard. Although both were rescued, the barge was destroyed on rocks downstream. Assumedly, the ferry operated at least until the permanent rail bridge opened in late 1902. A road or footbridge opened at least within a few years. In 1964–65,

729-664: Was operated partly by the current and partly by punting . Several reaction ferries crossed rivers in the Ozark Mountains of the central United States during the first half of the 20th century. The Akers Ferry across the Current River near Salem in Missouri remains in operation. Menor's Ferry in Jackson Hole, Wyoming, was a dual-pontoon reaction ferry built in the 1890s and operated until 1927. A replica
