On my 1979 Cheoy Lee Offshore
41 I have several dorades feeding fresh air into the cabin
. On the Dorade box sits the air scoop and directly behind it is a plate with a screw on cap. This cap if removed, opens to the hole that is the vent into the cabin
. Each Dorade is equipped this way. I cant really make up my mind why the extra cap and hole are there. I have thought that it might be so that you can change the position of the Dorade when in port in calm weather
so the air comes directly down the hole into the cabin. Other than that I am not sure why these extra plates are there. Does any one have any ideas. Or does anyone have a Cheoy Lee
and the original brochure. These Dorades are original to the boat from the pics I have seen from the Mfg.????
