Masts A mast is a post that has no cargo-handling gear. Masts can appear on the deck, bridge, or funnel of a ship. A mast on a king post is coded as a king post. In all instances, masts are coded if they are heavy enough to be easily discerned. A mast installed on a funnel is coded as if it were located forward of the funnel. A ventilator without cargo-handling gear is coded as a mast if it is prominent. Figure 13-3 1 shows the types of masts usually installed on merchant ships. King Post A king post is an upright with cargo-handling devices attached to it. Since king posts are designed for handling cargo, they are located at the forward or after end of a hatch. King posts may be arranged singly or in pairs. King posts located against the bridge, but not rising above it, are not coded. A funnel serving as a king post is coded as if it were located after the king post. A ventilator rigged for cargo-handling is coded as a king post if it is conspicuous.
