The principal objects of the invention are to provide a light 'weight sectional boat adapted when in knock-down condition to occupybut small space and capable of bemg easily transported in a pleasure motor vehicle or by a small trailer; one which is capable of being easily assembled, and where in the joints between the sectionsaremaintained Water tight, and wherein the means for maintaining the sections in assembled relation affords a plurality of braces longitudinally of the hull at spaced points throughout its full length.
The invention consists primarily in a plurality of metallic, preferably aluminum, hull sections, including intermediate and end sec tions adapted for nesting when disassembled to provide a compact structure requiring but little space in transporting, sections having interlocking connection at adjacent edges, there being provided a keel and there beinw provided flexible uniting member secured to one end section and engaeeahie with the other end section whereby the same extend lcngitudinall'y of the hull at s ced points on its outer surface, and there is h further ovideda means for maintaini the lexiuniting members under ten ll ith the above mentioned jects in view the invention co in the novel construction combination of parts hereinafter described, lustrated in the ac companying drawings and set forth in the claims hereto zwpended it being understood that various chang s in the form, propor 'tion, size andmi; ails of construction Within the scope oi L e claims sorted to Without dep or en 'iici m hoat illustrating the sections in assembled relation.

In t e drawings wherein like characters of reference designate corresponding parts, the boat is indicated generally by the numeral 1, and the same consists of a hull formed of a plurality of one piece metallic hull sections 2', preferably oi aluminun. The upper edges 01 the hull sections are bent over into tubular formation as at 3, The transverse rear edge of each intermediate hull section and the edge of the how secti each preferably hent outwardly an Wardly on at 5, and the rem"- the mat ial 3 turn be rallel which s orel e? suitable cutting mate edge of each intermed I he forward te section 2 the edge of the stern i by a relatively rein ced 12 re ined in po t? r by heudir over the e 13 ion in Figure Z. i e
. 1. oro-vides a water L 1 ssernhied se ne i i 3 6p! wardly i new and the how till provided with the well known keel portions 14, the adjacent ends of which are adapted to abut when the hull sections are in assembed relation as in the drawings. The keel sections are longitudinally grooved as at 15, as illustrated in Figure 4.
To provide a means for affording a plurality of braces longitudinallyof the hull and to retain the hull sections .in assembled relation with the calkings 10 under compression, I prefer to employ a plurality of flexible cables or members 16 each preferably secured to the bow section 4, flexible members or cables being illustrated as five in number. One member 16 is disposed to extend longitudinally of the keel 14 and to be received in the groove 15 therein, and two other members are attached to the bow section of the boat to extend in a straight line rearwardly therefrom substantially parallel with the load water line, and two others, those termed the gunnel cables are each one adapted to pass through the tubular portions 3. Each cable when in assembled position is adapted to be drawn tight, andto facilitate this tightening at its free end carries a threaded member 17, and these threaded members are adapted for reception within apertures in the plates 18 disposed radially of the stern-board 19 of the stern section 11, and to receive the takeup members 20 illustrated in the form of winged nuts. The as- I sembling of the parts as indicated in the lid drawings and the disposal of the cable 16, as illustrated, enables the sections during their assembly to be maintained with their interlocking edges one received Within the other and with the cables afi'ording' braces longitudinally of the hull for its full length exteriorly of the hull forming plates.'
WV hen it is desired to knock down the boat, it is only necessary to release the nuts 20, withdraw the flexible cable 16, separate the sections'Q, l, and ll, and nest the same for trans ortin l c aim 1. A knock down boat including a metallic hull divided transversely into a plurality of nestable sections, the metal at one transverse edge of each intermediate section being bent hackwardly upon itself and thence for-- wardly substantially parallel spaced relation to the hack bend to provide edge receiving channel extending substantially the full length of one transverse edge, the opposite transverse edge being provided for its full length with a reinforced member, a calking in the base of the channel, and means for detachably securing the sections into heat forming position,
2. A knock down heat including a metal lic hull divided transversely a plurality of nestalole sectiens, the metal one transverse edge of each intermediate section losing bent backwaraly upon itself thence for 'wardly in substantially parallel spaced relation to the back bend to provide an edge receiving channel extending substantially the full length of one transverse edge, the opposite transverse edge being provided for its full length with a reinforced member, a calking in the base of the channel, and means for detachably securing the sections into boat forming position, said means affording a continuous brace at spaced points longitudinally of the boat.
3. A knock down boat including a metallic hull divided transversely intol'a plurality of sect-ions adapted for separation from each other, an interlocking calked connection be tween the cooperating edges of adjacent sections, a plurality of flexible tie members secured at one end to one terminal boat section for extending longitudinally of the exterior of the hull on the assembling of the sections, and means forattaching said tie members to the other terminal boat section and for drawing the same taut.
4. A knock down boat including a metallic hull divided transversely into a plurality of sections adapted for separation from each other, an interlocking calked connection between the cooperating edges of adjacent sections, a plurality of flexible tie members secured at one end to one terminal boat section for extending longitudinally of the exterior of the hull on the assembling of the sections, and means for attaching said tie members to the other terminal boat section and for drawing the same taut, said tie members affording a plurality of braces longitudinally of the heat at spaced points on the exterior of the hull.
5, A knock down boat including a metallic hull divided transversely into a plurality of nestahle end and intermediate sections, the metal for substantially the whole length of one transverse edge of each intermediate section and the one transverse edge of one end section heing bent outwardly and backwardly on itself and thence forwardly in substantially parallel spaced relation to the hack bend, to provide an ripen-ended receivmg channel, the metal for sulostantially the whole lenr th cf the other transverse edge of each intermediate section and the edge of the other end section losing bent out wardly to provide'a pocket, reinforcing member held within the-pocket, callring in the base of the channel, a plurality of flexible tie members secured tc one end memloer, devices asseciated with the other end member for receiving the free ends of the tie mernloers, and take-up means associated with the tie members for maintaining the same taut when the heat secticns are in.

6. A lrnocn-dc-wn heat including a hull divided transversely into a plurality of seci, tions adapted for separation from each lid other, an interlocking connection between the co-operating edges of adjacent sections,
a plurality of flexible, tight members se cured at one end to one terminal boat section for extending longitudinally of the hull on the assembling of the sections, and means the [same taut, said tight members affording a plurality of braces longitudinally of the 10 boat hull to maintain the sections with their edges in co-operating relation.
In testimony whereof-I have signed my name to this specification.
