The Lintrose was a small iron twin-screw river steamer built in 1897 by Fleming and Ferguson of Paisley, Scotland, measuring 126.5 ft by 26 ft with a draught of 5.9 ft and a tonnage of 148. She was wrecked in 1932 near the Iron Pot while carrying telegraph poles, after her cargo shifted in heavy weather. The Marine Life Network guide places the wreck halfway between the Iron Pot and the next large rock to the north, in 2-5 m – very shallow at low tide – and notes that little remains apart from steel plate, the motor and a pair of steel propellers.

Even so, the twin propellers and engine are recognisable and make an interesting focus for a shallow dive or snorkel, and the wreckage has become encrusted with weed, sponges and small invertebrates that attract wrasse, leatherjackets and other reef fish. The site's shallow depth and proximity to the Iron Pot make it an easy add-on to a reef dive there. It is suitable for newer divers and snorkellers, though surge can be a nuisance in any swell.

The Iron Pot area has a long maritime history – the lighthouse dates from 1832 – and the Lintrose is one of several small vessels lost around the Derwent entrance. As with all historic wrecks, look but do not remove anything. Plan the visit on a higher tide to avoid grounding the boat and to give a little more water over the wreck.

A mask, snorkel and fins are enough for a good look on a calm day, while scuba divers can take their time photographing the propellers and the life that has colonised the steel.

South Arm is about 35 km (40 minutes) south-east of Hobart: cross the Tasman Bridge, follow the South Arm Highway (B33) through Rokeby and Lauderdale to South Arm. The main boat ramp is at South Arm (Blessington Street/Harbour area) with trailer parking and toilets; Lauderdale (Doran's Road) is an alternative ramp further north. The wreck is beside the Iron Pot, about 10-15 minutes from the South Arm ramp.

The Marine Life Network guide notes it can be located from the surface; approach carefully in the shallows, ideally not at dead low tide.

The South Arm peninsula and Iron Pot sit at the junction of the Derwent and Storm Bay. Western shores and the lee sides of the islands are sheltered from easterlies; eastern and southern faces are exposed to southerly swell rolling in from Storm Bay. Strong southerly winds and swell close the exposed sites; northerly and light westerly winds give the best conditions.

Visibility varies widely, from 3 m after Derwent floods to 15 m in clear marine water after a dry spell and a flood tide. Afternoon sea breezes can make the boat ride back choppy. The Marine Life Network suggests the Lintrose as an alternative to Betsey Island in rough weather, but at 2-5 m it is affected by any surge.

Anchor nearby in sand, swim to the wreck and survey the steel plating, engine and twin propellers, then explore the adjacent reef.

No regular operator; private boats and club divers, often combined with Iron Pot Reef.
