SS Kyarra (Swanage Liner Wreck)

Overview

The SS Kyarra is a 6,993-ton steel-hulled passenger and cargo liner built in Scotland in 1903 for the Australian United Steam Navigation Company. During World War I, she was requisitioned for the war effort and served as a hospital ship. In May 1918, while carrying a highly diverse general cargo bound for Australia, she was torpedoed by the German submarine UB-57 just off the coast of Swanage in Dorset. She sank rapidly, though thankfully with a relatively small loss of life (six crew members).

Today, the Kyarra rests upright on a seabed consisting of mixed sand and shingle at a maximum depth of approximately 30 meters (100 feet). The upper decks and hull plates have collapsed inward over the decades, bringing the shallowest sections of the wreck up to roughly 24 meters (80 feet). Because of the depth, the low light conditions, and the incredibly strong tidal streams that sweep the area, the Kyarra is strictly an advanced dive. It is not suitable for an open water course. However, for divers living in the UK looking for the best places to learn how to execute decompression procedures on a historic wreck, the Kyarra is a premier location.

The Dive Experience

Accessing the Kyarra typically involves chartering a hardboat or RIB departing from the nearby Swanage Pier or Poole Harbour. The transit is short, often taking less than 30 minutes from Swanage.

The dive is completely dictated by the tide. The currents rushing past Anvil Point are ferocious, and diving the Kyarra is only possible during the brief window of slack water. Divers must descend the shot line rapidly; missing the wreck can result in a long drift dive into the English Channel.

Visibility is generally fair, averaging between 5 and 12 meters, but it can drop significantly after heavy storms. Water temperatures follow the standard UK profile, peaking at roughly 16°C (61°F) in late summer. According to cold-water travel and packing guidelines, a drysuit is heavily recommended. Because the working depth of the dive is between 26 and 30 meters, the use of Enriched Air Nitrox (typically EANx32) is standard practice to extend bottom times and manage nitrogen loading.

What You’ll See

The Kyarra is famous within the UK diving community for its cargo. Because she was carrying general goods for civilian use in Australia, the wreckage is filled with fascinating artifacts. Over the years, divers have recovered brass portholes, medical supplies, sealing wax, and thousands of intact glass perfume bottles. While the most accessible cargo was salvaged long ago, winter storms continually shift the sediment, regularly exposing new artifacts among the collapsed hull plates.

The massive triple-expansion steam engines and towering boilers remain clearly identifiable in the midships section, providing impressive structural elements to navigate around. The wreck is also heavily colonized by marine life. Enormous conger eels reside in the pipework, while large edible crabs (brown crabs) and squat lobsters hide in the darker crevices. The wreck is continually shrouded in vast shoals of pouting and poor cod.

Planning Your Dive

Due to her immense popularity, the Kyarra is heavily booked by dive clubs throughout the summer season.

Artifact Policy: While the Kyarra has historically been heavily salvaged by recreational divers, it is crucial to recognize that the wreck is owned, and removing artifacts without express permission and proper declaration to the Receiver of Wreck is illegal under UK maritime law. Divers should focus on observation and photography, leaving the historical artifacts undisturbed for others to enjoy.
