[QUOTE=EO32;352842]So the purpose is to signal that you are a sailboat under power, whereas power boats only have a white stern light..../QUOTE]
Not quite! All power-driven vessels are required to show a white light forward. For vessels over 12 meters LOA, this must be a 225 degree white light, located on the centerline. For vessels under 12 meters LOA, the masthead (or steaming) light optionally may be carried as one 360 degree light (representing both the steaming light and the sternlight). Rule 21.
Power-driven dingys, by the way, are not exempted...they must carry sidelights and an all-round white light.
