yep need the forward facing white or all round white and with the seperation. The forward facing part of the white light is showing that you are a power driven vessel. As the visibility of the white is greater than the red/green it is in your own best interests anyway to ensure that you can be seen easily by someone looking through wheelhouse windows in the dark, cos it aint easy.
Over 50m (thats a BIG vessel) two forward facing whites are needed, highest one on the rearmost mast.
I work out of Ijmuiden in Holland a lot and the light arrays (towing/pushing lights,restricted manouverability, constrained by draught) coming out of there, one of the busiest ports in Europe, are awesome - incorrect arrays just add to the stress when you are trying to see whats what in the dark and rain.
