Dorade Boxes
 
<HTML><!-- eWebEditPro 1.8.0.2 --><FONT face=Arial><P>What is a dorade box? </P><B><P>Ralph Doolin responds:</P></B><P>In simple terms, a dorade box, or collector box, is intended to extract water from air intakes leading into the engine or other compartment. Although&nbsp;sizes and shapes vary from boat to boat, the principle is always the same. The Dorade Box is a single chamber system with a baffle between the intake air supply and the&nbsp;interior space-air feed. The baffle helps keep smaller water droplets from being carried through by the incoming air. As a result, most of the water ingested through the air intake drops to the bottom of the box and is drained away, either into the bilge, overboard through a dedicated vent above the waterline, through the hull, or to a sump, to be automatically pumped overboard. </P><P>This ventilation system was named after the yacht <I>Dorade,</I> which was designed, navigated, and sailed by American naval architect James Stephens. The <I>Dorade </I>was the winner of the 1931 Transatlantic and Fastnet races. We have an example of a dorage box pictured on our site in our Store here, you may see it by <A class=articlelink href="http://www.sailnet.com/store/item.cfm?pid=3348">clicking here</A>.</P></FONT></HTML>
