Of single screw DESCRIPTION The New York Cen- tral is the owner of a large fleet of harbor craft of all kinds. Its marine department in charge of this floating equipment is constantly trying to reduce cost of operation. Lighter No. 35 is propelled by a powerful diesel engine direct connected _ to propeller. Cruising speed is estimated at eight knots. diesel drive the vessel is at all times imme- diately ready for operation and while not being used there is a minimum expense for power. It is of the covered type and is used for the transfer of more valuable freight requiring protection from sea and weather. With the addition of Lighter No. 35, the New York Cen- tral fleet now consists of 45 self-propelled boats plying the waters around Manhattan. The proportion of beam to length is some- what greater than in the tugboat type giving greater deck room and increased stability and seaworthiness. A cruising speed of eight knots is possible with the single 600 horsepower diesel engine direct connected to the propeller. That this vessel is of heavy substantial construction and fully equipped in every way is indicated by the period of time necessary for construc- tion. The keel was laid in February 1930; launching took place Aug. 12, and the lighter was completed and delivered Oct. 15, 1930. With a fuel capacity of 24 tons, she has a cruising radius, when operating 10 hours a day, of about 16 days. It will be interesting to observe her perform- ance in practical service. The experience so gained will point quite definitely to the most satisfactory type of power for this important class of vessel for harbor work. ik ame es a heaes yi t ¥ i Sl. MARINE REVIEw—April, 1931
