Ship Cover for various yard craft, primarily coal, mooring, provision and victualling lighters,barges and tank vessels. A number of the lighters and barges are numbered/named, but are too small to appear in mainstream fleet lists and reference works. The only vessels of consequence [in terms of size] are the tank vessels Asp (1890), Monkey (1896), Tortoise (1897) and Chub (1897). The documentation is fairly eclectic, consisting mainly of basic design proposals/justifications, comparative tables of barge data, trial reports for some coal barges, statements of dimensions and weights, stability calculations, stores lists for various lighters, condition reports of existing vessels, general correspondence between the Admiralty, naval representatives and tendering firms, and abstracts of tenders with reference to numbers of barges and lighters required in yearly estimates. The Cover is generally organised by vessel type and port of deployment, and relates in this respect to major naval coaling/victualling bases in home waters and overseas. The date range covered by the papers is February 1877 to November 1907. A note among the documents for Monkey indicate further information on this ship is to be found in Cover 147.
