The Rotomahana (aka SS Rotomahana) was completed in 1879 in Dumbarton, Scotland. Said to be the first steel hulled steamer in the world, she had a clipper bow and graceful hull. She served for many years on the Melbourne to New Zealand routes and was known as the "Greyhound of the Pacific" due to her great speed.

Little other than the four massive boilers remain, although there are plenty of steel girders and other debris including the old bowsprit. Some penetration is possible between and underneath the boilers of the shipwreck.

The overall length of the vessel was approximately 90.89 metres (298 feet), beam 10.73 metres (35 feet) and draught 7.22 metres (24 feet) giving a displacement weight of 1,777 tonne (1,959 short tons).

The Rotomahana was laid up in 1921, purchased by a Melbourne ship breaker in 1925 and slowly stripped of valuables. On 28 May 1928 the tug Minah towed the Rotamahan from Station Pier, through the heads, and out into Bass Strait. Three former captains of the Rotomahana were aboard the pilot steamer Victoria to witness the scuttling by explosive charges.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
