ORDER FOR ARDROSSAN YARD
CONTAINER SHIP FOR COAST LINES

A container ship which, at 1550 tons gross, will be the biggest in their fleet, has been ordered by Coast Lines from Ardrossan Dockyard Limited. The order will provide about a year's work for the Ardrossan yard.
Equipped with an Atlas Polar diesel engine of 2800 brake horse power and designed for a service speed of about 12 knots, the new ship will join several others of the same type which are now being operated by Coast Lines.
The Spaniel and the Pointer, on the Liverpool-Belfast run, were converted from general cargo carrying to container carrying at the Ardrossan yard last year.
Coast Lines container ships are also operating on the Ardrossan-Newry run.
