To overcome this the present hull is formed with the outer-portion thereofof the usual'contour which is designed forthe best results in speed boats, and aninner shell in the shape of an inverted arch between which and the outerportion theremay be a filling of anylight but firm materiah'such'as balsa wood. 7 .o I :These important features are" attained by the novel design, construction and arrangement of parts hereinafterjdescribed and il- 'lustrated in the accompanying drawing, forming .a material .part hereof and in .Whl0h2 v s I v I Figure. 1 is aside-elevational view of an "embodiment of the invention as disposed with relation'to the surface of water.
