WETSUITS


A wetsuit is a garment, usually made of foamed or compressed neoprene, which is worn by surfers, divers, windsurfers, canoeists, and others engaged in water sports, providing thermal insulation, abrasion resistance and buoyancy. The insulation properties depend on bubbles of gas enclosed within the material, which reduce its ability to conduct heat. The bubbles also give the wetsuit a low density, providing buoyancy in water. Contrary to popular beliefs, the layer of warm water normally trapped between the wetsuit and the skin provides very little thermal insulation.

Semi-dry suits are effectively a thick wetsuit with better-than-usual seals at wrist, neck and ankles. The seals limit the volume of water entering and leaving the suit. The wearer gets wet in a semi-dry suit but the water that enters is soon warmed up and does not leave the suit readily, so the wearer remains warm. The trapped layer of water does not add to the suit's insulating ability. Any residual water circulation past the seals still causes heat loss. But semi-dry suits are cheap and simple compared to dry suits. They are made from thick Neoprene, which provides good thermal protection. They lose buoyancy and thermal protection as the trapped gas bubbles in the Neoprene compress at depth. Semi-dry suits can come in various configurations including a single piece or two pieces, made of 'long johns' and a separate 'jacket'. Semi dry suits do not usually include boots, so a separate pair of insulating boots are worn. They are used typically where the water temperature is between 10 and 20 °C (50 and 68 °F).

The Lydia shipwreck lies out from the shore opposite Lydia Place in Port Fairy Bay on Victoria's Shipwreck Coast. Port Fairy Bay is notorious for vessels dragging and parting with their anchors when southerly and south-easterly gales prevailed. A total of 30 vessels were wrecked in and around the waters of Port Fairy between 1836 until 1876.

Diving and Snorkelling the Lydia Shipwreck

Diving the Lydia shipwreck requires calm conditions and a very low swell. See WillyWeather (Port Fairy Bay) as a guide for the tide times and the height of the tide.

Lydia Shipwreck History — Built in 1825

The Lydia was a three-masted wooden barque of 277 tons, built in 1825, at Liverpool, United Kingdom.

At the time of its demise the Lydia was owned by its master P. Petrie and registered in Liverpool.

Lydia Sinking — 2 February 1847

When the barque Lydia called into Port Fairy en route from Sydney to London on 2 February 1847, the anchors were dropped in eighteen feet of water, although the vessel was drawing thirteen feet. As the tide began to fall, the Lydia started to strike the bottom in the swell. The sternpost was driven up and the vessel began to take water rapidly. To prevent his ship from sinking, the master Captain P. Petrie slipped the anchor cables and ran the Lydia ashore. Although the cargo was saved, the vessel was a total wreck.

Eastern Maar country
Eastern Maar country

Traditional Owners — This dive site is in the traditional Country of the Eastern Maar people of south-western Victoria between the Shaw and Eumerella Rivers and from Yambuk in the south to beyond Lake Linlithgow in the north. This truly ancient Country extends as far north as Ararat and encompasses the coastal townships of Port Fairy in the west, Warrnambool, Peterborough, Port Campbell, Apollo Bay, Lorne, and Airies Inlet in the east, including the Great Ocean Road area. It also stretches 100 metres out to sea from low tide and therefore includes the iconic Twelve Apostles. "Eastern Maar" is a name adopted by the people who identify as Maar, Eastern Gunditjmara, Tjap Wurrung, Peek Whurrong, Kirrae Whurrung, Kuurn Kopan Noot and/or Yarro waetch (Tooram Tribe) amongst others. We wish to acknowledge the Eastern Maar as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging.

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.
