A dorade is a type of ventilator that permits the passage of air in and out of the cabin or engine room of a boat while keeping rain, spray, and sea wash out. The basic form is a low, rectangular box fixed to the deck or cabin top, fitted with interleaving vertical baffles. The baffles alternate to be free at the floor of the box, or free at the ceiling, forming a series of chambers. A horn-shaped ventilation cowl is usually fitted facing forward to a large hole at the top of the chamber at one end of the box with another large hole opening down into the boat from the chamber at the other end. Limber holes perforate the wall of the box at the floor of each chamber. Dorade boxes operate on the principle that air can pass relatively freely through the chambers, yet rain or sea wash will be trapped in successive chambers and drain out the small holes in the sides of the box. The first appearance of Dorade boxes was on the Olin Stephens-designed Dorade, a yacht built in 1929 for ocean racing. As originally built, the Dorade's vents led directly below, but this was found to allow water below, and the vents were modified in the early 1930s.An early piece of marine equipment from the 1930s that still is in use today on smaller vessels to improve below deck ventilation.

A dorade is a type of ventilator that allows air to move in and out of a vessel's cabin or engine room but baffles or screens within the box it is fitted to prevent the rain and seawater from getting inside. A Dorade was first seen in use on the "Dorade", an ocean racing yacht designed by Olin James Stephenson II and built in 1929. Since then there have been modifications to the original design. The yacht, Dorade, could have been named after the Mediterranian dorade fish.An early piece of marine equipment from the 1930s that still is in use today on smaller vessels to improve below-deck ventilation.Dorade vent cowl; a cast brass ventilator.

Professor Arthur Barrington (Barry) Baker was the first Australian anaesthetist to gain a DPhil in anaesthesia. He completed his DPhil at Oxford University at the Nuffield Department of Anesthesia in 1971, titled, Physiological Responses to Artificial Ventilation. The Waveform Ventilator is the machine developed to illustrate his DPhil. The waveform ventilator was used in several scientific studies on 'the effects of varying inspiratory flow waveforms and time in intermittent positive pressure ventilation (IPPV)', published in the 'British Journal of Anaesthesia'. Professor Arthur Barrington Baker had an extensive career in research and clinical practice including holding the position as the Nuffield Professor of Anaesthetics at Sydney university (1992 - 2005) and also as the Dean of the Australian and New Zealand College of Anaesthetists (ANZCA) (1987-1990).The variable waveform ventilator is of national significance, due to its association with Professor Arthur Barrington Baker (Prof. Baker) the first Australian academic anaesthetist, and the representation of historical social themes and research and design, in anaesthesia. Historic significance – It is a rare type of ventilator in good condition and well provenanced. It is a tangible record of the beginning of the long established and distinguished career of Prof. Baker, the first anaesthetist in Australia to gain a DPhil. Prof Baker has a strong involvement in the Australian and New Zealand College of Anaesthetists (ANZCA) organisation. The object is a product of Prof Baker’s Doctorate of Philosophy (DPhil) on respiratory physiology and is associated with the prestigious Oxford University and the well-known Nuffield Department of Anaesthetics. It also represents the social theme of migration to England from Australia in the 1960s and 1970s to access and experience academic and artistic opportunities limited in Australia at the time. Scientific Value – The object is of scientific value as it offers major potential for education and interpretation in anaesthesia. Although ventilators are common equipment, this specific design and construct prototype is one of a kind, designed and used specifically for research purposes. A rectangular shaped object on a trolley with four wheels. The top half of the object consists of two panels, one of cream coloured painted wood, the other black plastic, both containing several dials of different shapes and sizes. The wood surface also contains several gauges and a safety pressure clear plastic box. The plastic surface also contains a pin board. The bottom half of the object consists of two shelves. The whole object's perimeter is lined with perforated metals. The top wooden surface has several metal pieces of equipment and a long tube. The rear of the object contains numerous types of tubing and wire, a gas cylinder and two leather straps with buckles. The bottom half of one side of the objects has 3 electrical power outlets.Waveform Generator, Drs Colliss N Cowie, Dr Baker Dr Murray Willson, Dr Babbington, Safety Pressure, Error POS F/B, Position, Feedback, Set Balance, Reset, Full Stroke, Velocity, Converter Current, line Pressure, Low Pressure, Bias Pressure, Start, Stop, Stop, Reset Press, Max Press, W/G Output, A/CRO B/2.baker, arthur barrington, baker, barry, professor, academic anaesthetist, oxford university, nuffield department of anaesthesia
