124 heavy construction and a_ design which aims toward maximum cargo capacity within the limitations of the . vessel. : ue The hull is 473 ft., 3 in. in length between perpediculars, with a molded beam of 57 ft. The depth of hold is | 31 ft., 10 in.; the molded depth to the -- upper deck is 35 ft. and to the shelter » deck is 42 ft, 6 in... The height be- tween decks is 10 ft. The vessel is. 5 built according to Lloyds classifica- tion No. 100-A. Her summer free- board is 5 ft. 61%4 in. from the main deck; the winter freeboard is 6 ft. 1 in. from the main deck. The length of the double bottom is 422 ft., 6 in.; the breadth and depth of the double bottom are 45 ft., 2 in. and 4 ft., 2 in., respectively. The frame spacing is 26 in. throughout. There .are three complete steel decks and one steel orlop deck forward. The sheer is 8 1, 3% 1%. forward. and: 4: ft. 1) in, aft. The net weight of steel. in the vessel is 3,912 tons. With a displace- ment of 17,800 tons the draught is 29 ft., 6 in. The displacement per inch of immersion is 55.5 tons. The. ratio of length to beam is 8.6 and of length fo dGepin, 15:1. it is interesting. to note that the length divided by the breadth of the Columbian is 8.86 and the same function of the passenger steamer H. B. Kennedy (described in the April Marine REVIEW) is only 6.8. This is a pertinent illustration of the deceptiveness of appearances, as the latter vessel is supposed to be, pro- portionately, much narrower, Bilge keels, 15 in. wide, are fitted. The cargo space is divided into four holds served by seven hatches. The dimensions of these hatches are shown on shelter deck plan. To handle the cargo to and from the ship there are two masts, four crane posts and two light posts at the forward end of the deck-house carrying in all twenty derrick-booms. These derricks are manipulated by 14 steam winches. Steam for the winches is. supplied from either main or donkey boilers.
