The colonial service Acheron-class torpedo boats were built by the Atlas Engineering Company at Sydney in 1879 for the New South Wales naval service. They were originally armed with a single spar torpedo, but this was replaced in 1887 with two 14-inch torpedoes. They were sold in 1902.
Design
The boats were designed by John I. Thornycroft & Company to mount a single spar torpedo. They displaced a mere 16 tons and were 78 ft 0 in (23.77 m) in length.[1]
Construction
In 1877 the Government of the colony of New South Wales ordered the construction of two "outrigger" torpedo boats, in response to concerns about a possible threat from foreign warships. Tenders closed on 17 January 1878 and the winning contractor was the firm of Atlas Engineering Company at Sydney. Both vessels were launched in early 1879 and Acheron started her trials in Sydney Harbour on 1 March 1879.[2]
| “ | The strange craft attracted much attention from the persons aboard the various yachts and steamers as she passed everything at a rate that made them seem to be comparatively standing still, even such boats and the Bellbird and Manly ferry steamers being relatively nowhere and being so small and low, the speed appears much greater than it would in a larger vessel | ” |

Service
Neither of the boats ever left the confines of Sydney Harbour, and they were never used in anger. By 1885 they were in a state of disrepair and were docked at Cockatoo Island. In the late 1880s they were described as "Sydney’s third line of defence", after the naval artillery and the defensive mines. Both boats were refitted again in 1896.[2]
Fates
On 1 March 1901 Acheron and Avernus became part of the Commonwealth Naval Forces. By this time they had become thoroughly outmoded and the Federal Government ordered their sale. In December 1902 Acheron was sold for £425 and Avernus for £502.[2]
Acheron became Sydney’s quarantine boat, renamed Jenner, and was paid off in the late 1930s. In the mid-1990s a workboat of the Royal Australian Navy detected a long thin hull with her side-scan sonar, which was thought to be the remains of Acheron.[2] On the other hand, after sale Avernus was abandoned on the shores of Rushcutters Bay and in the 1940s was sunk for reclamation of land at Glebe.[2]
