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. A' J' shaped hollow brass cylinder with a wide open mouth twisted to the side. The inside is painted. A Dorade vent is normally fitted into a chamber box but this was not included.Noneflagstaff hill, warrnambool, maritime museum, great ocean road, shipwreck coast, ventilator, dorade, vent, cowl, ship fittings, maritime equipment, ventilator box, dorade vent, collector box, cowl vent, olin james stephenson ii

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 and 40s that still is in use today on smaller vessels and ships.Dorade Cowl (Ventilator), brass casting with wide open mouth twisted to side.
