Saving lives in Warrnambool – The coastline of South West Victoria is the site of over 600 shipwrecks and many lost lives; even in Warrnambool’s Lady Bay there were around 16 known shipwrecks between 1850 and 1905, with eight lives lost. Victoria’s Government responded to the need for lifesaving equipment and, in 1858, the provision of rocket and mortar apparatus was approved for the lifeboat stations. In 1859 the first Government-built lifeboat arrived at Warrnambool Harbour and a shed was soon built for it on the Tramway Jetty, followed by a rocket house in 1864 to safely store the rocket rescue equipment. In 1878 the buildings were moved to the Breakwater (constructed from 1874-1890), and in 1910 the new Lifeboat Warrnambool arrived with its ‘self-righting’ design. For almost a hundred years the lifesaving and rescue crews, mostly local volunteers, trained regularly to rehearse and maintain their rescue skills. They were summoned when needed by alarms, gunshots, ringing bells and foghorns. In July 1873 a brass bell was erected at Flagstaff Hill specifically to call the rescue crew upon news of a shipwreck. Some crew members became local heroes but all served an important role. Rocket apparatus was used as recently as the 1950s. Rocket Rescue Method - Rocket rescue became the preferred lifesaving method of the rescue crews, being much safer that using a lifeboat in rough seas and poor conditions. The Government of Victoria adopted lifesaving methods based on Her Majesty’s Coast Guard in Great Britain. It authorised the first line-throwing rescue system in 1858. Captain Manby’s mortar powered a projectile connected to rope, invented in 1808. The equipment was updated to John Dennett’s 8-foot shaft and rocket method that had a longer range of about 250 yards. From the 1860s the breeches buoy and traveller block rocket rescue apparatus was in use. It was suspended on a hawser line and manually pulled to and from the distressed vessel carrying passengers and items. In the early 1870s Colonel Boxer’s rocket rescue method became the standard in Victoria. His two-stage rockets, charged by a gunpowder composition, could fire the line up to 500-600 yards, although 1000 yards range was possible. Boxer’s rocket carried the light line, which was faked, or coiled, in a particular way between pegs in a faking box to prevent twists and tangles when fired. The angle of firing the rocket to the vessel in distress was measured by a quadrant-type instrument on the side of the rocket machine. Decades later, in about 1920, Schermuly invented the line-throwing pistol that used a small cartridge to fire the rocket. . The British Board of Trade regularly published instructions for both the beach rescue crew and ship’s crew. It involved setting up the rocket launcher on shore at a particular angle, determined by the Head of the crew and measured by the quadrant, inserting a rocket that had a light-weight line threaded through its shaft, and then firing it across the stranded vessel, the line issuing freely from the faking board. A continuous whip line was then sent out to the ship’s crew, who hauled it in then followed the instructions – in four languages - on the attached tally board. The survivors would haul on the line to bring out the heavier, continuous whip line with a tail block connected to it. They then secured the block to the mast or other strong part the ship. The rescue crew on shore then hauled out a stronger hawser line, which the survivors fixed above the whip’s tail block. The hawser was then tightened by the crew pulling on it, or by using the hooked block on the shore end of the whip and attaching it to a sand anchor. The breeches buoy was attached to the traveller block on the hawser, and the shore crew then used the whip line to haul the breeches buoy to and from the vessel, rescuing the stranded crew one at a time. The rescue crew wore scarlet, numbered armbands and worked on a numerical rotation system, swapping members out to rest them. This rocket launcher key is a necessary part of the equipment for the the rocket launcher, which is significant for its connection with local history, maritime history and marine technology. Lifesaving has been an important part of the services performed from Warrnambool's very early days, supported by State and Local Government, and based on the methods and experience of Great Britain. Hundreds of shipwrecks along the coast are evidence of the rough weather and rugged coastline. Ordinary citizens, the Harbour employees, and the volunteer boat and rescue crew, saved lives in adverse circumstances. Some were recognised as heroes, others went unrecognised. In Lady Bay, Warrnambool, there were around 16 known shipwrecks between 1850 and 1905. Many lives were saved but tragically, eight lives were lost.Key, part of the Rocket Rescue equipment.
