Serial No 528,174. assembly. A of the 'boat is built of'steel or N This invention relates to a boat construction,the general object of the invention being to form a light-weight boat of strong structure by forming the frame of the boat of aircraft tubing or channel steel, all parts of which are welded together with the planking T fastened to the frame with self tapping sheet metal screws and the framing beingconnected at the sides to metal members which act to stifien the boat longitudinally and also act to support a coaming in a'water proof manner.
Another object of the invention is to pro" vide a waterproof flooring in the lower part of the boat which forms with the bottom part of the boat an air chamber which may be divided "into compartments by waterproof bulk heads so as to prevent the boat from sinking when damaged below the water line.
This invention also consists in certain other features of construction andin the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended Figure 1 is a perspective view of, the frame of the boat constructed in accordance with this invention. a

or brazed or connected by gussetplates and boltswhere necessary; I f
As shown in Fig.1, the frame'Ais 'composed of a plurality of transverse members which passes through recesses 5 formed in the central portion ofthe bottom partof the members and the'upper ends of each of the members 13 is bent inwardly asshown'at 6 B which are connected togetherby a keel 4 and connected'tothe longitudinal members 7 n which act'as longitudinalstiifening and bracing members, and'also as supports for coaming. These members 7 are connected to the side portions of the member B by the diagonal bracesS. These members 7 may extend from the stern frame to the first frame or member B having cross beams for'the decking incorporated in its structure, orthey may'extend {)hroughout the length of the boat in undecked oats.
As shown in Fig. 2, the framing maybe shaped to provide around bottom boat or it theflooring 10, and thecross members 9am bracedbythe bracesll. i V The flooring 10, the planking 12 and the coaming (not shown) arepall fastened to the frame by the self tapping sheet metalscrews are covered on both sides with airplane fabfabricwaterproof.

The screws 13 which. passthrough the front ends of the planking also pass through the plates 18 and the tube 17. Thenose member 19 is of substantially triangular shape, and abuts the front end of the planking and is fastened to the tube 17 by meshed-metal screws 20. a r v p 1 From the foregoing it will be seen thatwe have provided a light-weight boat, the framing of which is formed of any suitable metal of tubular, channel or other suitable cross sectional shape, and the parts"ofwhich"are .all iwelded, brazed'or otherwise connected together, the boat being provided with airtight compartments in its lower, part to prevent the boatfrom sinking and all thewoodenv parts are covered with aeroplane fabric or the like treated with aeroplane dope to prevent dry I rot and to make the parts waterproof.
v The boat can be constructed at low cost 7 and has great strength andv is of, light-weight equipment.
and, is thoroughly seaworth. Each channel member is built up from three strips'of sheet steel,.the center one straight and bent as need- 7 ed, andjthe outer ones out, curved as needed and welded together so as to form a boat rib ofthe proper shape without necessity for further "bending after the strips are .welded together.
A boat rib of this construction would be as strong asadi-est amped one and uch easier to make (with less expensive ,It is thought from the foregoing description that the advantagesandnovel features of the invention'w ill be readily apparent.
