November, 1909 steamer represents the most advanced ideas in tank ship construction. A study of the vessel reveals the three principal requirements upper- most in the mind of the designer: Am- ple strength to battle with the heavy storms encountered on long voyages, especially those which frequently rage in the vincinity of Cape Horn; large cargo capacity coupled with reason- able speed, and finally, ample bunker capacity and large steaming endur- ance for long trips. The hull is 'built of steel to Lloyds classification and is provided with special stiffening members on _ each side just forward of the funnel as well as a center longitudinal bu'khead which divides the port and starboard oil tanks and gives the vessel consider- able additional longitudinal strength. The vessel is 360 ft. in length be- tween perpendiculars, 49 ft. 'beam, with a morded depth of 29 ft. 4 in. to upper deck. Her deadweight capac- ity on 24-ft. draught is 6,100 tons. The engine and boilers are placed amid- ships, with cargo tanks both forward and aft. There are three cofférdams; both fore-and-aft and transverse oil tight bulkheads separate the various oil tanks from each other and from other parts of the vessel. There are four oil holds forward of the ma- chinery and three aft; each hold con- tains two tanks, one port and one starboard, making 14 tanks in all. In addition there are four small summer tanks situated aft of the engines and above the main tanks. When carrying creosote under or- dinary conditions No. 1 tanks and No. 7 'tanks are not loaded. The capacity of the vessel in tons, carrying creo- sote is as follows: : Tank Tons NO ea POR feces shee ose Sees os ene 439 Os, 2.5 Statboatdl © ep Hare ous 5 vere wieieee' eel 439 INO; 3; port 62.40.
