SS Wyola was a 306 GRT steam tug built in 1912 by LT Eltringham & Co of South Shields, England for the Swan River Shipping Company of Western Australia. Wyola was 125 ft (38 m) long between perpendiculars, had a beam of 24.7 ft (7.5 m), a depth of 13.1 ft (4.0 m) and a draught of 14 ft 0 in (4.3 m). Her 179 NHP (1,200 horsepower) triple-expansion engine gave Wyola a speed of 11.5 kn (21.3 km/h). She was also fitted with a powerful salvage pump, making her one of the most powerful tugs in Australia at that time.
