X-LIGHTERS

A listing of the 'X' series of lighters built as an emergency measure during the First World War

The X-class lighters, nicknamed 'Black Beetles', were designed by Walter Pollock, naval architect of James Pollock & Sons Ltd. but none were to be built by the company's own shipyard which was established at Faversham in 1916. The craft were born out of the need for a basic, shallow-draft powered 'landing craft' and many were equipped with a hand-operated ramp extending over the spoon-shaped bow, while others were completed as water tankers and later saw service as fuel tankers. The first batches, completed in 1915 were towed out to the Mediterranean in time to see service in the ill-fated Gallipoli campaign. Later, some took part in the Russian campaign based in the White Sea. They were among the earliest 'small craft' to be equipped with oil engines, the majority with the 'hot bulb' engine by Bolinders of Sweden, for whom Pollock's were the U.K. agent.

Those which arrived in the Aegean were given additional 'K' numbers for troop carriers and 'L' numbers for water tankers. Some were subsequently sent to Mesopotamia and designated 'ML' for motor lighter.

Some remained in naval service but the majority were sold post-1918 and saw long service as dry cargo and tanker vessels in the short-sea and estuarial trades, especially on the Thames and Medway.
