				LAUNCHES ON THE WEAR AND AT WEST HARTLEPOOL
Northern Echo 7/5/28
The monitor ship Rio Diamante, which has been constructed by William Gray and Co., of West Hartlepool, successfully completed her official sea trials on Saturday. The vessel is one of comparatively few monitor ships constructed in this country, their peculiarity being a series of corrugations which run from end to end of the ship. Their purpose is to minimise rolling, provide more cargo space, and obtain the maximum thrust from the screw. In the trials of the Rio Diamante the absence of roll was most noticeable, and the vibrations from the engines were also distinctly minimised.
 
Messrs. William Gray and Co., Ltd., have launched from their Central Shipyard, West Hartlepool, the s.s. Carperby, another fine addition to the Ropner Shipping Co., Ltd., of West Hartlepool. She is 418ftft. in length, 53ft 6in. broad, and 29ft. 6in. in depth. Triple expansion engines will be supplied by the Central Marine Engineering Works of the builders. 
The christening ceremony was performed by Miss Clare A. MacGregor, daughter of Dr A. V. MacGregor, of West Hartlepool.
