The Aagot was a three-masted iron barque built in 1882 (in Glasgow, per earlier records), a typical deep-water sailing ship of the grain and timber trades. On 12 October 1907 she struck rocks on the western side of Wardang Island, at the place now called Carpenters Rocks, and became a total loss. The Department for Environment and Water notes her remains are scattered both underwater, at about 4 m, and ashore.

More than a century of south-westerly swell has broken the barque into fragments – iron plates, frames, knees and fittings wedged among the rocks and partly covered by weed and moving sand. Earlier surveys noted weed cover of 10-50% on the wreckage, and the site's appearance changes as sand shifts. Fish life is typical of shallow gulf reefs: sweep, old wives, magpie perch, leatherjackets and wrasse, with crabs and octopus under plates.

The Aagot is one of the less-visited wrecks on the Wardang Island Maritime Heritage Trail because it is on the exposed western shore and so shallow that surge dominates. On a flat day, though, it makes an atmospheric snorkel, and it combines easily with the Investigator and Notre Dame d'Arvor a little further south. It suits snorkellers and divers who enjoy piecing together scattered wreck sites, visiting on the calmest days.

Remember that Wardang Island is Aboriginal land: wreckage ashore should be viewed from the water unless landing permission has been obtained. The trail booklet published by the Department for Environment and Water and the Port Victoria Maritime Museum's displays give useful background and photographs of the barque before her loss, which help in interpreting the scattered pieces underwater.

From Adelaide drive about 190 km (2 hours 15 minutes) via Port Wakefield and Maitland to Port Victoria. Launch at the Port Victoria boat ramp beside the jetty and run west to Wardang Island – the island's nearest shore is about 8 km away and the southern wreck sites about 11 km (20-30 minutes in a small boat). The Port Victoria Maritime Museum and the Department for Environment and Water trail booklet give site details and coordinates.

Wardang Island is Aboriginal land held by the Point Pearce (Narungga) community: diving the wrecks from a boat is fine, but landing on the island requires permission. The Aagot is at Carpenters Rocks on the exposed western side of Wardang Island, about 10 km from the ramp (25-30 minutes), reached by running around either end of the island. Anchor well off the rocks in sand; approach only in low swell.

Wardang Island lies 8-11 km off Port Victoria in Spencer Gulf. Its western and southern shores – Aagot, Investigator, Notre Dame d'Arvor, Monarch, Australian and MacIntyre – face the open gulf and are subject to south-westerly swell, surge and wind-driven sand movement, so they need low swell and light winds, ideally easterlies. The eastern and northern sites (Songvaar, Moorara) are more sheltered from the prevailing south-westerlies but exposed to northerly and easterly chop.

The 20-30 minute boat run from Port Victoria becomes uncomfortable above about 15 knots. Summer and autumn mornings are the usual window; winter fronts bring days of south-westerly weather. The Aagot site, among rocks on the western shore, is badly affected by surge, current, wind and moving sand; it needs genuinely flat conditions.

Snorkel or dive along the rocks at 2-4 m following the scattered plating and frames, keeping out of the surge line, and return to the boat.

No regular operator; occasionally visited on Wardang trail weekends and by private boats.
