The steamer Sheaf Crown, built by Messrs. William Gray and Co., Ltd., to the order of the Sheaf Steam Shipping Co., Ltd., Newcastle–on–Tyne, successfully ran her official sea trials on Friday.

The vessel, which is of the open shelter deck type, takes the highest class in Lloyd’s Register, and is of the following dimensions: Length overall 418ft. 4in.; breadth, 54ft. 6in.; depth moulded to upper deck, 24ft. 10 ½ in

She is constructed on the cellular double bottom principle with deep channel framing, and has six watertight bulkheads, together with a steel centre line bulkhead and wood shifting boards dividing the holds for grain carrying. The fore and aft peaks are suitable for water ballast. A Tutin balanced rudder is also fitted.

Spacious accommodation for the officers is arranged in a steel house amidships. The engineers are berthed in large steel houses alongside the casing, with the necessary mess room and lavatory accommodation. Large airy accommodation is arranged in the forecastle for the crew, including separate dining rooms.

For the quick handling of cargo, 11 7in. x 10in. steam winches are provided which work eleven derricks. A direct-acting steam windlass forward and steam steering gear amidships are also to be fitted. The masts are suitable for the Manchester Canal Bridges.

                                          A FIRST-CLASS CARGO STEAMER.

The vessel is complete in all respects as a first-class cargo steamer, and has an efficient wireless installation and electric light throughout. The propelling machinery, supplied by the Central Marine Engine Works of the builders, consists of reciprocating engines of the balanced quadruple inverted direct acting surface condensing type, to work at a pressure of 260lbs.per square inch. The boilers will be worked under forced draught and are fitted with superheaters. They are arranged to burn either coal or oil fuel. A number of auxiliaries of the “CMEW” type, are also fitted, including centrifugal circulating pump, pair of independent feed pumps, overhead direct contact feed heater, high pressure live steam surface feed heater, harbour feed pump, general service and ballast pumps. Singlex oil transfer pump, pair of oil fuel separators, evaporator, auxiliary condenser, steam scrubber drain and scumming tank and gravitation feed filter.

A “CMEW” thermocouple installation will also be fitted, be means of which the temperatures of the gasses in the combustion chambers of the boilers, smoke boxes, the base of the funnel and other points may be easily and conveniently read at one place in the engine room.

The owners were represented on the trial by Mr. W. A. Souter, Captain Clarke, and Mr. Keith Scott (Messrs. Jos. R. Scott and Sons, Newcastle), under whose supervision the ship and machinery have been built.
