A method of making a marine indicia marking on the surface of a steel hull, and the product produced thereby. The method comprises establishing a preconceived pattern for the marking and welding a plurality of nipples to the outside of the hull conforming to the pattern. Preferably, stud arc welding is used to weld the nipples to the hull. The stud used in the stud arc weld gun is of the knock-off variety and includes an upper knock-off portion and a lower permanent stud. After installation, the surface of the stud may be made smooth by grinding or other suitable methods. Finally, the studs and adjacent portions of the hull surface are painted with contrasting color paint.
