Drysuit Undergarments


Drysuit undergarments (or undersuits) are worn beneath the dry suit to provide much of the actual insulation for the scuba diver and have a large impact on the enjoyment of a dive.

Undersuits are used for providing additional warmth when diving, traditionally under a drysuit but some are now ideal for use under a wetsuit as well. Undergarments are available in a wide range of styles, thickness grades and materials, spanning from the thinnest (e.g. Northern Diver Thermalskin) up to the much thicker and more thermally insulating (e.g. Northern Diver Metalux Arctic).

For cold-water use, especially diving under ice sheets, the user will usually wear a thick undersuit in a membrane drysuit. The thickness of undersuits varies and can be chosen by the wearer according to the water temperature. Thinsulate or Fleece (e.g. Northern Diver Arctic Base) is one of the preferred fabrics for undersuits. More recently, aerogel material is being added to conventional undergarments to increase the insulating properties of those garments.

Neoprene drysuits are made from a foam-rubber sheet containing tiny air bubbles, which provide insulation by themselves, and can eliminate the need for an undersuit, or greatly reduce the thickness needed for the under fabric. A neoprene wetsuit can also be worn under a membrane drysuit for extra protection against condensation and leaks.

Malaita Shipwreck History

The Malaita was a steel, single screw steamship, built in 1893, by Grangemouth Dockyard Co in Grangemouth, UK, as the Antilla, for the Bahamas Steamship Co Ltd, Nassau. The vessel's dimensions were a length of 200 ft (61 m), beam of 30.2 ft (9.2 m), and draught of 12.3 ft (3.75 m). The vessel was Units: unknown unit type given, and Units: unknown unit type given.

The vessel was damaged by fire in 1904, then purchased in 1905, reconditioned and renamed the Malaita by Burns, Philp & Co, for trade in the Pacific islands. Bought by Huddart Parker in 1914, its engine and boiler were removed and she was converted into a coal hulk. Later sold to Moreland Smelting Co Ltd, in 1919, and towed from Sydney to Melbourne in three days where the engines of the paddle steamer Excelsior were installed. As a steamer once more, the Malaita made several voyages to New Zealand and the Pacific Islands as a cargo ship. She was eventually laid up at anchor in Hobsons Bay.

After partially destroying the South Melbourne baths when she broke her moorings and drifted ashore in a storm on 17 Dec 1926, the Malaita was put back into service, but was soon withdrawn again.

Malaita Sinking

On Tuesday 20 November 1928 the steamship Malaita was towed out into Bass Strait by the tug Minah and scuttled in the Victorian Ships' Graveyard.

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.
