POOL CO.’S NEW SHIP.
SUCCESSFUL TRIALS OF THE s.s. ROCKPOOL.
Northern Daily Mail. 16th Nov 1927
The steamer Rockpool built by Messrs. William Gray and Co., Ltd., to the order of the Pool Shipping Co., Ltd., West Hartlepool, successfully ran her official sea trials yesterday.
The vessel is built to the highest class in Lloyd’s Register, and is of the following dimensions: Length overall 418ft.; breadth, 53ft. 6in., depth moulded to upper deck, 29ft. 5 ½ in., with long bridge, poop, and forecastle. It is interesting to note that the deadweight carrying capacity is about the same as in a number of other steamers recently delivered by Messrs. Gray to the same owners, but the Rockpool is 15ft. longer with 18in. less beam, and has a finer model. There modifications illustrate the modern insistence on improved steaming performances.
The ship is constructed on the cellular double bottom principle, with fore and aft peaks, for water ballast, the framing being of the deep channel type, and has six watertight bulkheads, together with a steel centre line bulkheads, and wood shifting boards dividing the holds for grain carrying.
Spacious accommodation for the officers is arranged in a steel house amidships. The engineers being berthed in large steel houses alongside casing, and the crew in cubicles in the forecastle, with separate mess rooms.

For the quick handling of cargo, ten powerful steam winches are provided to work 12 derricks. A direct-acting steam windlass forward and steam steering gear amidships are also fitted.
The topmasts are telescopic, lowering to a height suitable for the Manchester Canal Bridges.
The vessel is completed in all respects as a first-class cargo steamer, including an efficient wireless installation and electric light throughout.
The propelling machinery, supplied by the Central Marine Engineering Works of the builders, consists of triple-expansion engines, having cylinders 26, 43, 71 inches diameter x 48 inches stroke, and three boilers working at a pressure of 180lbs per square inch.
