Used to work for me this way if departing a ship to return to that ship:
Plot point of departure with chinagraph on windscreen - plot to scale your track - plot to same scale ship track - when ready to return apply wind vector to your position - plot track from end of wind vector to ship's new position - assess bearing/distance and head home. Used to out navigate most baby "lookers".
