Dorade Boxes for Boreas

These dorade boxes drain off any water entering the cowl ventilator and can be closed off entirely by means of the incorporated, internal stainless steel mushroom ventilator. The mushroom ventilator also includes a mosquito screen.

Male-threaded deck rings of Vetus Cowl Vents, made of either stainless steel or plastic, can be easily fitted to the dorade box using the nuts and bolts supplied.

These BOX75, BOX100, and BOX125 boxes have a top section made of plastic and a stainless steel base section which houses the mushroom ventilator.
They are designed to fit the modern designed Broeas, Levanter and Mistral Cowl Vents, but also work with the traditional (old) style Donald, Jerry, Tom and Yogi Vetus Cowl Vents.


SV Dorade —
Dorade boxes are designed with internal baffles to capture and drain any water entering a cowl vent, before it can find its way into the boat's cabin.
They were first used on the 1929 racing yawl, "Dorade" - from which their name is derived.

Dorade boxes are traditionally rectangular. The cowl was mounted at one end, and had a long neck inside the box which extended downward, almost to deck level. At the other end of the box the deck opening to the cabin had a similar long neck, but extending up, almost to the top of the box.
In practice, the box would have to fill almost entirely with water before it could find its way down into the cabin.
Drain holes along the bottom of the box allowed water to easily drain before it could reach the level of the intake tube.
