Abstract

Novel nautical craft with a sail or a motor. The invention relates to the conversion of a sailboard into a microlight and fast nautical craft which can be handled by a single person. It can navigate in narrow and shallow waterways. It consists of a sailboard 1, of a cabin 2 stuck onto the board, with a stick rack fixed onto this cabin, of a sliding seat 3 which facilitates the position of the pilot in driving the craft. Incorporated into this seat, a safety device has been fitted, consisting of a push-button (3bis). Two compartments 4 and 5 allow various storage. The intermediate wall of these two compartments serves to support and fix the engine. The shaft of the engine will be inserted through an opening 6 made in the board. Two stabilising floats 7 on the third at the rear of the craft allow good equilibrium and greater stability. Control of the engine may be direct or remote. The assembly is moulded as a single unit, made from plastic and glassfibre.

Description

The present invention relates to a new nautical craft with motor or sail, for use at sea, lake or river.

It has been known from a windsurfing board, co-equipped in a real ultra-light and fast boat, - it can be propelled by an outboard motor or a sail.

 today, there are nautical devices using 2 or more windsurfers connected together, of the catamaran or trimaran type, may require 2 or more people to be able to move them on a trailer or on the gallery of a car, given their weight and their size. To remedy this drawback, a nautical sailing or motorized craft has been designed from a single windsurfing board. The advantages compared to current devices are its lightness, its small size, its ability to navigate in narrow waterways and to be handled by one person.

 This nautical device allows various leisures, for example: - Line fishing or trolling (with rod holders incorporated).

-Submarine fishing; -The walk.

-The race.

 It allows you to navigate in shallow waters (40 to 50 cm minimum).

 Composed of a windsurf board (1) as long and as light as possible, of a cabin (2), large enough to hold various storage spaces, made of plastic material, coated internally with glass fibers bonded with resin, on the Flanche. A removable door on which is fixed a rubber gasket which allows a complete sealing. This door is adapted to the cabin by means of two screws and two wing nuts.

 Two rod holders made of two P.V.C tubes, having an inside diameter allowing the introduction of fishing rods, are fixed to the wall of the cabin, on each side of the door.

 A removable keel (9) can be introduced into the opening of the board, intended for this purpose. The spoon can be used when the engine is not running. It allows greater stability of the machine when stationary, because, if it is running, it prevents normal guidance with the engine. It can be used if you are sailing.

A seat with backrest (3), made of plastic or plywood, supported by an aluminum frame, can be moved forwards or backwards by means of two elastic or aluminum slides, screwed and glued to This seat allows the pilot to move very low (5 to 6 cm above the board), so the slightest imbalance is avoided. I1 also allows the pilot to place himself in the ideal position in relation to the balance of the craft and his driving. A safety system consisting of a push button, fixed in the middle of this seat, allows to open or to close the electrical circuit of the engine. When the pilot leaves his seat, the engine stops instantly. A plug (mix-female) inserted in the circuit allows the pilot, as soon as he wishes, to establish or cut "the system this security't. The engine can work without having to press the button, on the condition Once the plugs are disconnected. Once the plugs are connected (device C; safety engaged), the pilot must be seated on the button for the engine to work. This device consists of a push button of the "ringing" type, with a inner spring harms it always upwards. In this position, two blades on the lower part of the button are in contact, so as each blade is connected to a wire, they produce a short circuit. You have to press the button to cue the blades separate and thus the motor trav-ille. (fig.3 bis)
A compartment (4), in plywood or plastic, with a sliding drawer-style cover, is used to store various items. The rear wall of this compartment serves as support and support for the outboard motor.

 A second compartment (5) in plywood or plastic, located in the rear part of the machine and constituting externally a single block with the first, is arranged so that a rectangular opening (6) can allow the introduction motor shaft (short shaft motor). In order to be able to follow up on this opening, the slide was cut at this location.

The walls of this opening are covered with plywood or plastic allowing a complete seal towards the board and towards the compartment (5). This compartment is completely waterproof, it also serves as an additional float, and it allows the storage of various items of board or other, for example: a
small battery for lighting or other purposes to be considered.

For access to this compartment, a small sliding cover is fitted on the upper part.

 The engine to be adapted to this machine has a ccurt shaft and less power than the CV. It can be controlled directly with the handle or be controlled remotely by means of two. levers fi xed to the outer part of each slide and connected to the engine by the cable and sheath system in the style of bicycle or motorcycle brakes. One lever pulls in one direction, the other, in the other direction. For the accelerator, a pedal is attached to the front, on the cabin (1, door side, and connects to the carburetor by the cable and duct system. In both cases, the two control systems are maintained and independent. For sail propulsion, the hole for fixing the mast in the board has been preserved.

 To give this machine a high degree of stability both when stationary and when in operation, two stabilizing floats have been designed with two PVC tubes, of sufficient length and diameter to allow @@ guer without fear. They will thus train with the teach @@@@ trimaran. These floats are supported with metal supports which pass above the board and which have at each end a colliewr of the diameter of the tube. The tubes are plugged at each end in a conical shape.

 Dotted lines, foreshadowing of the engine, the sail, the rods and the keel.

 All the unreadable parts of the machine are screwed and glued to the board. They can be molded at the time of manufacture of the latter in a single block.

 or the front part of the machine has been fitted a tow hook.
