Model of Richardson’s Tubular Life-boat. [Exhibited by W. Varlo Hellyer, Esq., M.R.I.] The Inventor, H. T. Richardson, Esq., in a paper accompanying the Model, stated that “ the Tubular Life-boat cannot upset, sink or be water-logged, can beach through a heavy surf on any sandy or shingle shore, and pull off again without the aid of anchors ; steers, rows, and sails well. Its extra buoyancy is six tons, ex- clusive of its own weight, which is within two;—it rows sixteen oars, and carries two lug sails, a jib and top sails—and can row and sail at the same time. In construction it is totally different from all other boats, being formed of two metal tubes forty feet in length, by two and a half diameter, tapering at either end in a manner so as to give the appearance of sheer. An iron frame- work securely rivetted unites the whole into one complete mass, the tubes having longitudinal bars of iron and hoops within, and iron keels running from end to end. They are divided into water-tight compartments, have air-proof bags in the four corners, and the two middle are filled with cork ; a ■ cork fender also surrounds the whole fabric. The rowers and passengers are placed on a platform above the frame-work, which is surmounted by a light gunwale the height of the row-locks; a rope passes along under the keelson for the purpose of towing.
