Figure 13-32.—Types of king posts. appear in pairs abreast, they are coded as a single crane. When located outboard from, and in line with, a mast, the crane is coded as if it were located forward of the mast. When two cranes are mounted on the same pedestal but are arranged fore and aft, they are coded as two cranes. Figure 13-33 shows examples of cranes. Gantry A gantry is unique in appearance and function. Typically, the gantry spans the width of a ship and has a boxlike shape. It also has the ability to traverse fore and aft along the ship's deck line, stopping over cargo holds. Figure 13-34 shows an example of a gantry. Funnels No distinction is made between the shapes of funnels on merchant ships. Funnels are not coded if they are so small that they are difficult to see, including the small pipes found on some motor ships. Though extremely rare, a few ships still exist with funnels that resemble king posts. Such funnels are coded if they appear after the king post. Funnels paired athwartships are coded as a single funnel. Figure 13-35 shows examples of funnels. BOW AND STERN Bows and sterns can also assist in the identifica- tion of ships. Bow types (fig. 13-36) are as follows: Straight, plumb, or vertical—This type is the oldest type; it offers the most resistance to the sea. Raking or sloping, and curved and raking— Angle varies greatly. Clipper or cable bows come within this group. 13-24
