Shipbuilding in iron and steel / a practical treatise . . n in place, the inside part of the stanchionis secured by the pin marked a, which is removed Avhen the top-sides are to be turned down, and they then move upon the hingemarked h.

In the Affondatore the bulwarks are in lengths Chap. XII. Topsides. 245 of 8 fee^inches, each length being secured by three hinges. Thebulwarks are lower than those of the Scorpion/and are made up of light plating (j^g-iuch), witha plain rail on the upper part, and stiffening angle-irons on the edges. The hinges are differentlyformed and secured from those of the Scorpion,as will be seen from Fig. 193. When in place thebulwarks are secured by stays similar to s, andT-iron and angle-iron stiffeners are worked uponthe bulwark plating in order to stiffen it in wakeof the stays. In these ships it is usual to place. Fi;;. 193. 246 Topsides. Chap. XII. the awning stanchions in such positions as to bring them be-tween two lengths of the bulwarks. A side view of one of thesestanchions, as fitted in the * Affondatore, is marked a in Fig. 193,and will serve as an example of the ordinary method of securingthem. In these low-decked vessels it is very essential to havethe means of speedily clearing the water from the deck; forthis purpose flap ports are fitted in the bulwarks, and are soarranged as to open outwards under pressure,.while they preventthe entrance of the water. It will be obvious that when thebulwarks were turned down against the side some difficulty wouldbo experienced in raising them again, unless special provision weremade for that purpose. In Fig, 193 there is given a separatesketch showing the plan adopted in the Affondatore. The bulwarkis shown turned down, and it will be seen that in order to give agood lead to the rope by whi
