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.”
