Gustav Adolph was a Norwegian barque of 757 tons built in 1879 in Arendal, Norway, and wrecked in 1902 on the South African coast some 90 km (56 mi) east of Cape Town.

[1][2] En route from Fremantle to Cape Town under Captain Anton Gjeruldsen (1862 Barbu, Norway - 1902) with a cargo of 14,000 jarrah sleepers, intended for use by the burgeoning Cape Government Railways, she was wrecked in a strong gale on 28 June 1902 just west of the Palmiet River mouth.

Drowned aboard the second boat were the Captain Gjeruldsen, two crewmen, and a Mr. Perkins, who was a clerk from Perth.

Gjeruldsen left behind his wife Inga, 10 years his junior and from Øyestad; a 1900 census showed that the couple were childless.

Two crosses made from salvaged timber were erected in memory of those who lost their lives.
