[0019] The drawings which illustrate presented invention and subsequently described examples of particular design do not in any case anyhow limit the extent of the protection stated in the definition yet merely clarify the essence of the invention.

THE EXAMPLES OF INVENTION DESIGNS

[0020] The kayak with additional drive is according to illustration in FIGS. 1 to 3 formed by a hull 1 whose part is a bottom 11 and a deck 12. In the hull 1 are formed a crew chamber 102 which is accessible from above through a boarding opening 121 which is made in the deck 12 and it is equipped with a seat 13, a waterproof back storage chamber 103 and behind it, in the back end part of the hull 1 of the kayak, is placed an engine chamber 104. The back storage chamber 103 is from the engine chamber 104 separated with a waterproof back screen 105. In the engine chamber 104 is placed a supporting frame 2 which is designed as a vertical flat board which is situated perpendicularly to the lengthwise axis of the kayak. To the supporting frame 2 of the kayak are fixed two lengthwise placed cooling bodies 21 in the shape of thin strips or bars adjoining from inside along sides to the bottom 11 of the kayak which are made from a heat conductive material. On the supporting frame 2 is, by the help of a flat engine frame 22 which is fixed to the supporting frame 2 and it is parallel with its plane, placed an electric engine 23 which is by the help of a transmitting element 25, preferably a chain or a toothed belt, coupled with a gear box 24 which is fixed on the supporting frame 2. An input shaft 241 of the gear box 24 is then situated in the area between the supporting frame 2 and the engine frame 22, whereas the input shaft 241 is parallel with an engine shaft 231 of the electric engine 23. The electric engine 23 is connected with a regulator 233 which controls its performance. On an unmarked protrusion of the gear box 24 is placed a drive element 26, preferably designed as a shaft, which is directed toward the stern of the kayak, in whose wall is waterproof way pivoted and is consequently in an axial direction taken out from the hull 1. On the back end part of the drive element 26 is then fixed a screw-propeller 27. The back end part of the hull 1 of the kayak is, in its lower line, finished with a protective barb 28 which overreaches not only lengthwise but also vertical outline line of the screw-propeller 27. To the hull 1 of the kayak is, in its back end part, around the vertical axis pivoted a helm 29 whose working area is situated behind the screw-propeller 27. In the front end part of the hull 1 of the kayak is removable placed a battery box 3, preferably waterproof, with batteries 33 to which is, by the help of electric conductors 31 through a safety switch 32 connected the regulator 233 which is then connected with a wireless receiver 232. The safety switch 32 is placed on an unmarked welt of a boarding opening 121. On the side wall of the boarding opening 121 is placed a potentiometer 235 with an integrated non-illustrated wireless transmitter which is connected with the wireless receiver 232 through which is the potentiometer 235 connected to the regulator 233. On the shaft 41 of kayak paddle 4 which is an essential part of the kayak, is placed a controller 234, preferably a button type, with a non-illustrated integrated wireless transmitter through which is together with the wireless receiver 232 is the controller 234 connected with the regulator 233.

[0021] Connection of the electric engine 23 with the drive shaft 26 by the help of a transmitting element and the gear box 24 is not only possible design. Alternatively the electric engine 23 can be connected directly to the drive shaft 26 as is it illustrated in FIG. 0.5.

[0022] In alternative design which is illustrated in FIG. 6 is the battery box 3 placed in a waterproof bow chamber 106 which is formed in the front end part of the kayak and is from the crew chamber 102 separated by a waterproof front screen 107. The bow chamber 106 is accessible through a bow opening 108 which is formed in the deck 12 and it is waterproof way sealable with a bow cover 109.

INDUSTRIAL USABILITY

[0023] The invention is usable for structures of primarily man powered small vessels for example kayaks or canoes designed especially for leisure time purposes.
