Scale: not calculated. A model of a launch which appears to correspond to an entry in the 1906 catalogue of the Museum of Artillery in the Rotunda, Woolwich (Class XXVII No.33), which lists a “Model of a launch, showing the plan adopted by Sir W. Congreve for using the rockets in Basque Roads”. It is equipped with a single oar, though it is fitted with ten thole pins. The model has been sturdily built to show a heavily framed and carvel planked boat that would withstand the shock of being used as a rocket-firing platform. The shallow draft and wide beam would have given the vessel stability, while the provision for ten oars would have been required to give the vessel optimum manoeuvrability. One suspects that the model is now incomplete; nevertheless it is an interesting and important item dating from the earliest development of rocketry.
