NEW STEAMER

CORRUGATED SIDES. DESIGNED TO SAVE COAL, FREMANTLE, This Day. On its maiden voyage to Australia, the steamer . Zuriehmoor, which was launched in England last July, was berthed at Fremantle, where it will lift a cargo of wheat. Other steamers having “blisters” running the length of the hull near the waterline have visited Australia, but the Zuriehmoor is a new type. It has two “blisters,” forming a central channel, and the corrugated sides give a grotesque appearance to its hull. Officers of the ship said the idea was to give increased space. It was contended that the corrugations gave a cleaner waterline between the two “blisters.” The water flowed along the channel between the “blisters” to the after end of the ship, where it converged in an unbroken flow on to the propeller. In the case of ordinary steamers the water which flowed on to the propellers was was more or lesfe broken water containing air bubbles, which robbed the*- revolving blades of some of their efficiency. The Zuriehmoor is fitted with superheated engines, which, together with the advantage of the corrugated sides, enable an average daily saving of four tons of coal compared with an ordinary steamer of the same size fitted with engines of similar power.
