I think girls make better navigators these days. As they are used to playing will all those switches on the cooker, kettle, microwave etc. Not much different from the tilt and gain and the comms. box's. In fact I think OASC should re think the aptitude tests for Nav's and bring in some Zanussi equipment and a pile of washing to see which candidate can wash, dry and iron the quickest!
Sorry to the female Nav's who know me.
