The rope is knotted to lock it in place at the of skilled labor. Another object of this invention is the provision of a sailboat whose hull is almost completely fabricated from plastic, thus requiring no painting or other maintenance, yet which is not subject to deterioration even in salt water. A further object of the present invention is the pro vision of a sailboat having a simple and rugged element which operates effectively ‘both as a rudder and as a keel. It is another object of the instant invention to provide a sailboat having a plastic hull with an unusual con ?guration of combing molded on its upper surface, where by the sailor is able to operate the boat without slipping and to balance his weight against the tilting produced by the wind. It is a further object of the invention to provide a sailboat whose hull is fabricated in an unusual way, so that its manufacture is inexpensive and, yet, results in an unsinkable quality. top of the mast. As has been stated, the sail is in the form of a right triangle made up from relatively narrow strips of nlyon cloth arranged with their lengths ex tending perpendicular to the long or free side of the sail. The vertical edge of the sail is provided with a hollow seam or hem 18 through which the mast passes and the horizontal edge is made with a similar hollow hem 19 in which a boom 21 resides. The ‘boom is formed of aluminum tubing reinforced with elastic foam. The corner of the sail at which the hems 18 and 19 meet is cut away and provided with a reinforcement 22. The reinforcement de?nes a small arcuate area in which the inner end of the boom 21 protrudes from the hem 19 and is provided with a ring 23 which loops loosely around the mast 13 as it emerges from the hem 18. The outer end of the boom is provided with an aperture. A rope 24 passes through this aperture and also through a grom met, not shown, sewn in the adjacent corner of the sail, and is then knotted. The rope hangs downwardly from A still further object of this invention is the provision the boom and is provided at its lower end with a small pulley or block 25. of a sailboat having a shallow-draft rudder and keel, with a rudder-actuating mechanism which is free of com as that of a surfboard, in that it has a boat-like plan, as The hull 11 has a shape which might best ‘be described plication and is unlikely to become entangled in Weeds 55 is evident in FIGURE 2, and a ?at upper surface 26 or the like. and a generally flat lower surface 27, the sides being quite straight or vertical compared with the curved sides With these and other objects in view, ‘as will be ap usually used in boats.

In sailing, the sailor ?nds a and 35 extend along the sides of the hull. The combing is smoothly streamlined into the shape of the hull and the inwardly-facing sides of the legs 34 and 35 are quite steep, as is particularly evident in FIGURES 5 and 6, sitting position which will allow him to shift his weight the easiest while regulating the tiller 44 behind his back. As the sailboat heels over, the sitting position allows him to put his feet against the combing for support. Oc to permit the sailor to lock his feet against them. A diamond-shaped mat 36 of cross-hatching is also molded into the surface of the hull between the legs 34 and 35, the grooves in the surface vbeing V-shaped, as is clear from an examination of FIG. 5. casionally this boat will capsize, due to its small keel and due to the fact that the sailor will be tempted to run with the boat heeled over as much as possible. It is quite easy to right it again if this happens. The sailor swims I The hull shape can be readily visualized from an ex 10 around quickly to the bottom of the boat and, at a posi tion forward of the keel-rudder, places his, knee against amination of FIGURES 3 through 8 which are successive cross-sections taken from the bow to the stern. It is clear that the upper surface 26 is fairly flat and, horizontal, except for the protuberance introduced by the combing 32. The lower surface 27, on the other hand, is ?at only in the center portion, as shown by FIGURES 5, 6, and 7; at the how it is smoothly curved, as is clear from FIG URES 3 and 4-; at the stern it is also smoothly curved, as is shown in FIGURE 8. The hull is considerably thicker in the center portion and the sides in this part of the boat are quite straight, although they merge smoothly with the upper and lower surfaces. The sides at the bow and stern have, a somewhat curved con?guration, as is particularly evident in FIGURES 3 and 8. A bore 37 extends downwardly through the main body 33 of the combing to retain the mast. The bore is rein forced by a short length 38 of aluminum tubing which is the bottom and reaches up with his hand 'to grasp the ' combing. He then pulls steadily, throwing his weight backwards. The water will slowly dump from the sail 15 and then the boat will upright. He then can head the boat into the wind and climb aboard for more sailing. A version of this sailboat which has proved extremely popular and practical had an overall length of 12'0", a width of 311/2”, a draft of 10'', a mast 17'0" in length, a sail which has dimensions of 14'0" by 8'6" (618 square feet, and a hull weight of 85 pounds; this boat was capable of carrying a crew of 350 pounds. It is obvious that minor changes may be made in the form and construction of the invention without depart 25 ing from the material spirit thereof. It is not, however, desired to con?ne the invention to the exact form herein shown and described, but it is desired to include all such supported laterally by the ?ller in the hull and at the lower end by a boss 39 formed on the inner surface of the bottom of the hull shell. Extending completely through'the hull slightly rearwardly of the mat 36 is a bore 41 reinforced by a short length 42 of aluminum tubing. Through this bore extends a rudder rod 43 which is provided with an enlarged upper end to prevent it from sliding downwardly as properly come within the scope claimed. The invention having been thus described, what is claimed as new and desired to secure by Letters Patent is: l.

To the upper end is keyed a wooden tiller 35 44 which extends forwardly and horizontally over the upper surface 26 of the hull. The lower end of the rud der rod 43 extends frornthe hull and is bent at a right angle to form an arm 45. which extends rearwardly of the rearwardly along the sides of the hull, the molding having a substantially greater width than height, the parting-line between the two parts extending in a horizontal plane parallel to the waterline, each part being separately ?lled The rearward end of the arm 45 is bent downwardly to with a plastic foam to the parting line. 2.
