United States Patent 3,111,691 SECTIONAL BOAT STRUCTURE Ormond Louis Luger, 9612 Oakland Ave. S., and Rennold J. Luger, Jr., 4505 Belvidere Lane, both of Minneapolis, Minn.

Filed June 22, 1959, Ser. No. 821,847 7 Claims. (Cl. 9-2) This invention relates to boat structures and more particularly to sectional boat structures.

In many conventional boat kit structures most of the separate component parts are left disassembled in order to permit compact packaging thereof. The assembly procedure of this kind of structure requires a high degree of craftsmanship and specialized tools since, for example, this type of boat structure is often made of wood material which often times requires many of the parts to be steam-bent. It is readily apparent that this assembly procedure of this type of boat structure is not only a complicated one but involves a rather time consuming operation. There are no known boat structures comprised of relatively few integral sections or parts and adapted for ready assembly without requiring specialized tools or the like and constructed in the manner so as to permit compact nesting thereof.

It is, therefore, a general object of our invention to provide a novel sectional boat structure of simple and inexpensive construction and arranged and constructed for rapid assembly.

Another object of this invention is to provide a novel sectional boat comprising a plurality of integral sections arranged and constructed for rapid assembly.

A still further object of our invention is to provide a boat structure comprising a plurality of integral sections arranged and constructed whereby said sections may be nested in compact relation.

These and other objects and advantages of our invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:

FIG. 1 is a view in perspective of the novel boat structure in its assembled condition;

3,1 1 1,691 Patented Nov. 26, 1963 "ice FIG. 13 is an enlarged fragmentary perspective showing a different manner forming the stern of the boat; and

FIG. 14 is an enlarged exploded fragmentary cross section of the embodiment disclosed in FIG. 1 indicating one manner in which the sections may be secured together.

Referring now to the drawings, the novel sectional boat is generally designated 9 and includes a unitary lower hull section 10, and intermediate hull section 11 and an upper hull section 12. These sections may be formed of molded material such as plastic, molded plywood or the like, but the preferred embodiment employs a waterproof tough material such as fiber glass in a suitable plastic binder or matrix.

The unitary lower hull section 10 comprises a bottom 13 whose width progressively narrows forwardly and also includes a conventional keel plate 13a. Bottom 13 has integrally formed side portions 14 extending upwardly and outwardly therefrom. Side portions 14 are elongated and converge forwardly to a bow portion and terminate in bow line 14a which as seen in FIG. 2 extends upwardly and forwardly. Bottom 13 terminates rearwardly in an upstanding wall portion 15 which includes an inwardly offset middle part 15a, longitudinally extending parts 15b, and transverse end parts 15c. Upstanding wall portion 15 is integral with bottom 13 and extends between and is integral with sides 14. The middle part 15a of upstanding wall 15 together with similar portions of other sections provide a mounting or transom for a conventional outboard type motor. This offset type stern, because of its spaced box-like portions, imparts additional buoyancy and stability to the boat. The sides 14 of the lower hull section 10 terminate upwardly in upper peripheral edges 16 which define horizontal attachment surfaces 17 adjacent the forward portion thereof and vertical attachment surfaces 18 adjacent the rear ends thereof.

Intermediate hull section 11 comprises elongated sides 19 converging forwardly to a bow portion and terminate in a bow line 20. Referring to FIG. 2, it will be seen that bow line 20 curves upwardly and forwardly and that the intermediate hull section 11 is of an overall length substantially less than the overall length of lower hull section 10. The elongated sides 19 of intermediate hull section 11 have substantially straight lower peripheral edges 21 which define substantially horizontal attachment surfaces 21a. It will also be noted from FIG. 3 that the upper peripheral edges 16 of lower hull section 10 are also substantially straight. The upper peripheral edges 22 of sides 19 extended from bow line 20 and are parallel with lower peripheral edges 21 over a substantial length thereof and curve rearwardly and downwardly to the lower peripheral edges 21 as at 23. The upper peripheral edges 22 of elongated sides 19 define substantially vertical cooperating attachment surfaces 22a.

The upper hull section 12 includes sides 24 which are elongated and converge forwardly to a bow line 25. Referring to FIG. 3, it will be seen that sides 24 of upper hull section 12 have lower peripheral edges 26 which extend rearwardly from bow line 25 and present a relatively straight surface 26a over a substantial length thereof. Lower peripheral edges 26 curve downwardly at an intermediate part 26b and terminate rearwardly in a substantially straight surface 2450. Again referring to FIGS. 5 and 6, it will be noted that the straight surfaces 260 define substantially vertical cooperating attachment surfaces 27a and the curved surfaces 26b of lower peripheral edges 26 define substantially vertically cooperating attach ment surfaces 27b While the straight peripheral surfaces 26c define substantially vertical cooperating attachment surfaces 27c. The upper edge of sides 24 is substantially straight and whereby said sides 24 are of greater height adjacent their stern or rearward portions than that of their bow or forward positions.

The upper hull section 12 includes a deck 28 integrally formed with and extending between said sides 24 adjacent the bow line 25. Deck 28 includes relatively narrow, spaced side deck portions integrally formed with and extending from the rear edge 28a thereof. Side deck portions 29 extend reanwardly and terminate in inwardly offset enlarged stern deck portions 30 to thereby define a cockpit 31. Referring now to FIGS. 1 and 2, it will be seen that the rear edge 28a of deck 28 terminates in a downwardly extending flange 32 while side deck portions 29 and stern deck portions 30 have their inner edges terminating in depending flanges 33. Upper hull section 12 also includes an upright wall portion 34 which extends between and is integrally formed with flanges 33 of stern deck portion 30. The rear edges of each respective side 24 and its flanges 33 are joined by a vertical section 33a. It will also be noted from FIG. 1 that upright wall portion 34 is offset inwardly from the rear ends of sides 24.

Referring now to FIGS. 5 and 6, it will be noted that cross sectional Widths taken at given points along the intermediate hull section 11 and the upper hull section 12 are greater than corresponding cross sectional widths taken at similar points along lower hull section 10. This relative difference in width size permits the lower hull section to be nested within the intermediate and upper hull sections when packaged for shipping. When the various sections of the boat are prepared for shipping, the upper hull section 12 is first inverted with the deck 28 disposed downwardly. Intermediate hull section 11 is then also inverted and the upper peripheral attachment surfaces 22a thereof are positioned upon the lower cooperating attachment surfaces 27a and 27b of upper hull section 12. It will be noted that the lower peripheral edge portion 26c of upper hull section 12 and lower peripheral edge 21 of intermediate hull section 11 define a substantially horizontal plane. The lower hull section is then placed within the inverted intermediate and upper hull sections 11 and 12 respectively with its bottom 13 disposed downwardly. The height of the section thus nested, as seen in FIG. 4, is no greater than the height of the side of a given section.

In the preferred embodiment, lower hull section 10 is provided with a plurality of hollow ribs 35 which may be molded separately from the lower hull section 10 and which may be form-ed of suitable plastic or fiber glass material embedded in a suitable plastic matrix or binder. Lower hull section 10 is preferably provided with thwarts or seats 36 which may be molded of fiber glass or plastic material.

Thwarts 36 may be provided with conventional seat backs (not shown) which together with the thwarts give lateral reinforcement to the assembled boat at spaced transverse points. A self-bailing motor well 36b as shown in FIG. I may be provided between the rear thwart and the transom and is securely bolted in place when the boat is fully assembled. The self-bailing motor well permits water to be discharged therefrom in a manner well known in the art. In the preferred embodiment, the boat is also provided with a pair of receptacles 360 which are positioned above and adjacent the front thwart 36 and which reinforce the seat back. It will be noted that each receptacle 36c opens rearwardly and comprises a unitary element which may be secured to the inner flange of the upper hull section. Each of the receptacles 36c may be formed of suitable plastic or fiber glass material embedded in a suitable plastic matrix or binder.

It will be noted that the accessories and parts including thwarts 36, self-bailing motor well 36b and receptacles 360, etc, are of such inherent unitary structure to thereby permit them to be disposed within the nested sections.

When the boat is assembled, the upper hull section 12 is inverted and placed upon a floor or supporting surface with the deck disposed downwardly and the engagement surfaces thereof are coated with a suitable plastic cement material. The upper engagement surfaces of the intermediate hull section 11 are also coated with a suitable plastic cement and the intermediate hull section is thereafter inverted and positioned in place upon the upper hull section with the respective lower peripheral edges of the upper hull section 12 engaging the upper peripheral edges of the intermediate hull section 11. Bolts 37, as shown in FIGS. 5 and 6, or clamps or the like may be employed to maintain the attachment surface in binding contact.

A plurality of supporting means such as barrels may then be disposed within the confines of the upper and intermediate hull section and the lower hull section 10 is inverted and placed thereupon with the bottom 13 disposed upwardly. Referring now to FIG. 14, which shows one manner in which the lower hull section 10 is secured to the intermediate and upper hull sections 11 and 12 respectively, it will be seen that a strip of fiber glass material 17a is cemented to the lower attachment surface 21a of intermediate hull section 11. The upper attachment surfaces of the lower hull section 10 are thereafter coated with a suitable plastic cement material as is the strip 17a and the lower attachment surface 27c of the upper hull section 12. The intermediate and upper hull sections 11 and 12 respectively are then lifted whereby the respective lower attachment surfaces thereof engage the upper attachment surfaces of the lower hull section. Bolts or clamps or the like may also be used to maintain these attachment surfaces in their secured binding contact. In order to assure an effective watertight seal along the inner juncture line of the assembled sections, we have provided another strip of fiber glass material 17b as shown in FIG. 14.

Referring now to FIG. 7, the upstanding wall portion 15 of the lower hull section 10 and upstanding wall portions 34 of the upper hull section 12 are secured together to thereby define a stem or transom of the assembled boat. In order to provide a transom having suflicient structural strength to support a substantially heavy outboard motor, these upstanding wall portions are bolstered by a pair of panels 38 disposed on either side thereof and secured in abutting relation against upstanding wall portions 15 and 34 respectively by any conventional securing means such as bolts 37 or the like. The panels may be formed of any suitable material such as plywood or the like. It will be noted from FIG. 1 that the upstanding wall portion 15 and sides 14 of the lower hull section together with the stern deck portions 30, sides 24 and upstanding wall portion 34, of upper hull section 12 define box-like floats which, of course, impart additional buoyancy and lateral stability to the stern deck portion of the boat. When the boat structure is assembled, bow lines 140, 20 and 25 comprise an upwardly and forwardly curved prow line.

Referring now to FIG. 13, a different manner of forming the stern or transom portion of the boat is disclosed wherein the side 24 of the upper hull section terminates rearwardly in transversely extending flanges 39. The bottom 13 of the lower hull section terminates in an upwardly extending flange 40 and the sides 14 are provided with inwardly and laterally extending flanges 41. It is pointed out that the flanges 39, 40 and 41 are formed integrally with the respective hull section and provide means for securing a transom panel 42 thereto. Panel 42 is slightly inclined from the vertical and may be secured to the flanges of the respective hull section by bolts 43 or the like.

Referring now to FIG. 8, it will be seen that we have provided as a different embodiment of this invention, a two sectional boat designated generally 50 comprising a unitary upper hull section 51 and a unitary lower hull section 52 which in the preferred embodiment is formed of fiber glass and a suitable plastic binder or matrix in the manner of the first embodiment of the novel sectional boat. The unitary lower hull section 52 comprises a bottom 53 which width progressively narrows forwardly similarly to the above described three sectional boat. Bottom 53 also has integrally formed side portions 54 extending upwardly and outwardly therefrom and which are elongated to converge forwardly to a bow portion and terminate in a bow line 55. Bottom 53 terminates rearwardly in an upstanding wall portion 56 and, of course, is provided with upper peripheral edges 57 having attachment surfaces for attachment to the lower peripheral edges of the upper hull section 51.

The upper hull section 51 comprises elongated sides 58 converging forwardly to a bow portion and terminating in a bow line 59. The upper section 51 also includes an upstanding wall portion 60 adjacent the rear ends of the sides 58. Referring now to FIG. 9, it will be noted that the overall length of lower hull section 52 is substantially less than the overall length of upper hull section 51. Upper hull section 51 may also be provided with .a deck 61 integrally formed with and extending between the sides 58 adjacent the bow line 59 which together with sides 58 and upstanding wall portion 60 define a cockpit opening 62. Since the overall length of the upper hull section 51 is substantially greater than the overall length of lower hull section 52, the respective sections may be nested with the lower hull section 52 disposed and nested Within the upper hull section 51. One Way of accomplishing this nesting is by inserting the bow end of the lower hull section 52 through the cockpit opening 62 of the upper hull section 51 whereby the bow portions of each respective section are disposed closely adjacent each other in the manner shown in FIG. 9. Sectional boat 50 may be assembled in the manner of sectional boat 9.

Additional parts or accessories such as thwarts, seat backs, a self-bailing motor well, etc., may be provided and, such parts, of course, will be disposed in the nested sections in the manner set forth describing the first embodiment of the invention.

Referring now to FIGS. 10, 11 and 12, it will be seen that we have provided as a third embodiment of the invention, a three sectional boat designated generally 80 comprising an upper hull section 81 and intermediate hull section 82 and a lower hull section 83, each section formed of fiber glass and a suitable plastic binder or matrix in the manner of the other embodiments described above. The unitary lower hull section 83 may include a bottom 84 having a width which progressively narrows forwardly and may include a conventional keel plate 84a integrally formed therewith. Bottom 84 also has integrally formed side portions 85 extending upwardly and outwardly therefrom and which are elongated and converge forwardly to a bow portion and terminate in a bow line 86. Bottom 84 may also terminate rearwardly in an upstanding wall portion 87 which extends between side portions 85. Sides 85 of the lower hull section 83 terminate upwardly in upper peripheral edges 88 which define horizontally extending attachment surfaces 88a.

Intermediate hull section 82 comprises elongated sides 89 which converge forwardly to a bow portion and terminate in a bow line 90. Intermediate hull section 82 may also include an upstanding wall portion 91 adjacent the rear ends of sides 89. Elongated sides 89 of intermediate hull section 82 terminate downwardly in substantially straight peripheral edges 92 defining attachment surfaces 93 for attachment to the upper peripheral attachment surfaces 88 of lower hull section 83. Sides 89 of intermediate hull section 82 also terminate in upper peripheral edges 94 which define attachment surfaces 95.

Upper hull section 81 includes substantially shallow sides 96 which are elongated and converge forwardly to a bow point 97. In the preferred embodiment, the side portions 96 of the upper hull section 81 are not interconnected with a rear wall section and the stern ends thereof terminate in free stern ends. Upper hull section 81 may also be provided with a deck portion 99 integral with and extending between sides 96. Deck portion 99 together with sides 96 define a cockpit opening 100.

Sectional boat may also be provided with thwarts or seats of the type described in the other embodiment and may also include the self-bailing well also described with respect to the other three sectional boat. Sectional boat 80 may also be assembled in the manner set forth describing the assembly process with regard to the other three sectional boat.

Referring now to FIG. 11, it will be seen that three sectional boat 80 is nested in a manner somewhat differently than that of the sectional boat 9. It will be noted that the peripheral edges of the respective sections of sectional boat 80 are in substantial parallel relation with each other and that the attachment flanges associated with each section is disposed in a substantially horizontal plane when the boat is assembled. It will also be noted, of course, that the lower hull section 83 has an overall length substantially less than the overall length of the intermediate hull section 82.

To nest three sectional boat 80, the lower hull section is inverted with the bottom disposed upwardly and the intermediate hull section 82 is placed thereover with its lower peripheral edges 92 disposed downwardly. The order of nesting these two sections may be reversed whereby the lower hull section 84 is disposed within the intermediate hull section 82. In order to obtain a compact nested relationship the upper hull section 81 is thereafter inverted with the deck 99 disposed downwardly and with the attachment flanges 102 thereof resting on the attachment flanges of the intermediate hull section 82. It will be noted, of course, that the bow end portions of their respective sections when so nested are positioned adjacent each other and the resulting nested relationship permits the nested sections to have a height or depth approximately the height of the side of the intermediate section 82.

Although not shown in the drawings, it is contemplated that the accessories and parts including thwarts, seat backs, self-bailing motor well, etc. may also be provided to this embodiment and may be disposed within the nested sections to thereby present a shallow package.

It will thus be seen by the preceding paragraphs that we have provided a novel sectional boat which includes relatively few integral sections having structural shapes and details to permit rapid assembly thereof. It is also apparent from the foregoing description that the various sections of our boat are so arranged and constructed that the use of specialized tools is obviated and the structure may be assembled by one having no specialized knowledge of boats. It is also apparent from the above description that this novel boat structure is of such inherent construction that the same may be nested into a compact assembly for packaging thereof.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of our invention which consists of the matter shown and described herein and set forth in the appended claims.
