NEW TUG’S PILOT HOUSE CAN BE RAISED OR LOWERED (Dec, 1933)
NEW TUG’S PILOT HOUSE CAN BE RAISED OR LOWERED
Equipped with a movable pilot house that can be hoisted to a height of twenty-two feet above the waterline, or lowered to ‘ the main deck, one of the strangest of tow-boats is being built for service on the Chicago River. Its design gives the pilot the elevated point of vantage necessary for maneuvering a long string of barges, while providing for the fact that the vessel must pass under bridges where the clearance is only twelve feet. When a bridge is approached, cables will lower the pilot house, and a motor-driven hoist will raise it when the obstruction is passed. The 113-foot craft will be driven by a 550-horsepower Diesel engine and will have three rudders, one in the usual position and one on each side of the propeller shaft.
