So far, the most reliable technique I have found for dealing with bow windage is to use my 25lb lead 'drudging' weight. Just let it go over the bow when the boat is in midstream, wait a few moments while she settles head to wind and then motor slowly ahead, recovering the weight as you go.
Whilst waiting for the boat to settle head to wind, there is time to light the pipe that John Morris probably assumes us old fuddy-duddy long-keelers smoke.
