Patented Apr. 5, 1932 UNITED vsrxrss RICHARD J'. `IEOGOGIK, 0F MILIEGRD, CONNECTICUT :BEACH BOAT Application `iled November, 1930. Serial No. 494,261.

This invention relates to boats and more particularly to a relatively flat raft type 'of boat which may be termed a beach boat, as it is well adapted for use about beaches by bathers in swimming costume or the like. It

will be understood, however, that the embodiment of my invention which I have illustra-ted and described is not limited to this use, but may be used as a duck boat, rowboat, or canoe, andis also adapted to be used for surf riding', or may be towed behind a motor boat as an aquaplane.

One object of the invention is to provide a boat suitable for use around bathing beaches or in shallow water which will have great stability and be very buoyant and of light weight. Y

Another object of the Vinvention is the provision of a boat ofthe type described which may be used in shallow water and which will be relatively light in weight so that it may be transported easilyf from place to place and may be readily drawn out of the water upon the beach desired.

A still further object o f the invention 1s the provision of a relatively flat boat which will be very buoyant and stable and will ride waves or rollers easily so that the interior of the boat will not be filled with water.

Another object of the invention is to, provide a relatively flat boat having a hollow body, the boat being shaped to a suiicient extent to ride waves which may be encounf tered, and which will have substantially no suction in mud or sand, such as is customarily encountered in the case of a boat having a flat bottom.

A still further object of the invention is to provide a light and stable and non-sinkable type of craft for use lin water sports so constructed that it may be manufactured economically and at the same time be a practical type of boat which may be put toa great variety of uses.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the drawings:

Fig. lis a top plan view of a boat embodyingmy invention;

ig. 2 is a slide elevational view of the` same ' Fig. 3 is a sectional view on line v3 3 of Fig. 1, and

Fig. 4 is a sectional view on line 4-4 of Fig. 2.

The boat which I have selected to illustrate and describe as a preferred embodiment of my invention, comprises, as will be observed from an inspection of the drawings, a hollow body of `raft-like appearanceexcept that it is shaped to some extent to provide a depressed Vinterior or upper surface, and a convex or. depressed lower surface. be observed, these upper and lower surfaces are substantially parallel although this characteristic is not absolutely essential, and variation in this respect may be resorted to if desired. l

The frame of the boat may, and preferably does, comprise crossed beams extending diagonally between the opposite corners ifV the boat is of rectangular shape as shown. As shown, these

beams

10, 11, 12 and 13 extend inwardly and'downwardly from the respective corners to have their inner ends embedded in or secured to a block 14 disposed substantially at the centereof the craft.' It will be noted from Fig. 3, for example, that each of these beams extends downwardly in an inclined position so that the upper surface of the block 14 will lie somewhatv below the corners andsides of the boat'so as toprovide a dished ordepressed upper surface which constitutes'the interior of the boat.

Secured upon the upper surfaces of the diagonally" extending beams, by any suitable means such as nails or screws, are p-ieces of

ply board

15, 16, 17 and 18. In the form of boat shown, these pieces of ply board are of triangular shape meeting at the center of the boat 19 on the upper surface of the block 14. Suitable crossbeams 20 may be provided wherever desired to give suiioient rigid support to the ply board between the diagonals.

The sides and ends of the boat areV then closed by the

end members

21 and 22, and the sidemembers'23 and 24. It will be under- As will stood that the pieces of ply board forming the upper surface of the craft are also secured to the end and

side members

21, 22, 23 and 24C so as to be supported at their outer edges by thesel members. It will also be understood that glue may and will preferably be used at the joints between the ply board and the supporting members where water-tight joints are desired.

The bottom of the boat is substantially a duplicate of the upper surface in that it will also consist of four pieces of ply board 25, which, like the ply board forming the upper surface of the boat, will be secured to thediagonal and crossbeams and the side and end members and glued where desired. As the diagonal beams extend downwardly from the corners, it will be apparent that both upper and lower surfaces of the boat will extend downwardly in aninclined direction from each of the sides and ends toward the central portion of the craft. As the

diagonal beams

10, 11, 12 and 13 are of uniform depth, the upper and lower surfaces of the boat are substantially parallel although this may be varied, if desired, and the vbeams made wider at one end than at the other so that, if desired, the hollow interior may be of greater height at the center than at the side edges.

It will be observed that as shown, the upper and lower surfaces of the boat are substantially pyramidal in form, the bottom surface projecting downwardly toward the center so that the bottom of the boat will be slightly inclined to enable it to ride the waves or rollers and the sides will be suliiciently elevated so that the waves will `not break thereover. Likewise the concave interior or upper `surface of the boat provides for a greater stability, as the occupants may sit near the central lower portion thereof.

v On'the otherl hand the upper surface is sufficiently -flat so that the entire surface may be used, if, for instance, one wishes to lie upon the boat for a sun bath or use it, as a raft for diving or the like, or for surf riding or aquaplaning.

Y Oar locks 26, 27, 28 and 29 may be provided at Vboth the sides and ends of the boatso that it may be rowed in any direction, or it may, of course, be poled or sculled if desired. Rope or cable loops 30 may also be provided at the corners so that the boat may be towed, or these may be used for bathers to hold on to the Yboat while learning to swim. These loops' may be passed through vertical openings 31 in

theend beams

21 and 22.

In order that the interior of the boat may be drained in case any water should seep therein, the diagonal beams and also the crossbeams 20 are provided with openings 32, which, when the boat is upended, will allowV the water to drain down to one end where it may pass out through an opening 33 in the end member 21. It will be kunderstood that the opening 33 will be kept plugged when the boat is in use.

Although, in the embodiment of my invention shown in the drawings, the boat is of substantially rectangular shape, it will be obvious that the invention is not limited in this particular, as the ends may be rounded or maybe pointed if desired.

While I have shown and described a preferred embodiment of my invention, it will be understood that itis not to be limited to all of the details shown, but is capable of modification and variation within the spirit .of the invention and within the scope of the appended claims.
