Historical information

This rocket launching machine is used in conjunction with the Dennett Rocket Set. Both are part of the rocket rescue equipment that launches the line-throwing rescue rockets. A light line is threaded through the carved holes in the 8 foot long shaft and attached to the scribed channel at the base of the shaft. The rocket head is fitted to the shaft and inserted into the machine. The machine is set at an angle determined by the person in charge of the rescue crew, and the legs and base of the machine are adjusted accordingly with the use of the quadrant, or protractor, and plumb-bob on the side of the machine. The rocket is then ignited and fired across the vessel in distress.

John Dennett -

John Dennett was from Carisbrooke, in the Ilse of Wight, UK. In 1826 he invented, patented and demonstrated an improved method of rocket powered, line firing rescue equipment for saving lives. The rockets had a longer range than the mortars being used, they were lighter, needed less preparation time, only needed one line for repeated shots, and fewer people were needed to move the equipment. Very favourable reports of Dennett’s rockets were received by those in charge of His Majesty’s Naval and Military services. In 1832, Dennett’s rocket-thrown line was sent out to the wreck of the ‘Bainbridge’, and was responsible for nineteen survivors coming ashore in two boatloads, along the fired line. Dennett’s rocket received national fame, and a one-year contract to supply rockets to the Coastguards. He became known as ‘Rocket Man’ and his rockets were used in rescues at least until 1890, when his son Horatio was running the business. A rocket weighing 23 lb would have a range of about 250 yards (228 metres), on average.

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. In 1859 the first Government-built lifeboat arrived at Warrnambool Harbour and a shed was soon built to house it. In 1858 the provision of rocket and mortar apparatus was approved for lifeboat stations in Victoria, and in 1864 a rocket house was built to safely store the rocket rescue equipment. In 1878 the buildings were moved to the Breakwater area, and in 1910 the new Lifeboat Warrnambool arrived with its ‘self-righting’ design. For almost a hundred years the lifeboat and rocket crews, mostly local volunteers, trained regularly to maintain their rescue skills. They were summoned when needed by alarms, gunshots, ringing bells and foghorns. Some became local heroes but all served an important role. By the end of the 1950s the lifeboat and rescue equipment had become obsolete.

Rocket Rescue Method -

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 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 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 tally board was then sent out to the ship with instructions in four languages. The ship’s crew would haul on the line to bring out the heavier, continuous whip line, then secure the attached whip block to the mast or other sturdy part the ship. The rescue crew on shore then hauled out a stronger hawser line, which the ship’s crew fixed above the whip block. The hawser was then tightened using the block on the shore end of the whip. The breeches buoy and endless whip are then attached to the traveller block on the hawser, allowing the shore crew to haul the breeches buoy to and from the vessel, rescuing the stranded crew one at a time.

Significance

This rocket launcher machine 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.

Physical description

Rocket launcher, named a Rocket Machine, and storage box. Launcher has a long open metal channel with a spike at the base, and narrow, rectangular device, which is the line-firing rocket machine, at the top, all painted blue. Two hinged wooden legs are attached where the channel and machine meet. The side of the machine has an oval cut-out window and an attached quadrant, or protractor, with a plumb-bob on it. The quadrant has angles marked in degrees. The long protective box has white stencilled letters along the side. Its lid has three hinges and is fastened with two metal latches.
