The white flag bears a blue star, recalling the early Blue Star Line trading name. US Navy 1961 attributes the livery to H.C.S. Coasters.
The Log calls the funnel yellow, while Mitchell shows orange in two line drawings, leaving the shade uncertain.
Harold Crofton Sleigh began his Melbourne business in November 1895, advertising Melbourne–Western Australia sailings as Blue Star Line. The brief Australian Transport venture with John McIlwraith was sold to AUSN in 1897. Sleigh returned to shipowning in May 1924; after his death in 1933 his son Hamilton succeeded him. Golden Fleece was the petroleum trade name. The later public company originated in 1947 as Golden Fleece Petroleum, subsequently H.C. Sleigh and Caltex Properties. Maritime subsidiaries included Singapore Navigation, formed in 1950, Kowloon Navigation, formed in 1957, and Dominion Navigation, which took over Singapore Navigation’s fleet.
Sleigh’s 1959 bid for Adelaide Steamship failed, as did a later Ampol bid for Sleigh and a proposed Boral merger. Caltex became a substantial shareholder and partner in Australian Tanker and Botany Bay Tanker; Sleigh sold those tanker interests in 1982. Dominion Far East Line and Flinders Shipping were ventures with Jardine, Matheson. Shipping interests faded around 1980. The later holding concern became Petersville Sleigh under Adelaide Steamship control and acquired an interest in Howard Smith in 1988.
