    The invention relates to a method of assistance from a boat participating in a regatta. It also relates to the device implementing the method.
    BACKGROUND
    In a race regatta, the boats must not cross the starting line before the start, otherwise it will be necessary to turn around to then return to the starting line.
    This starting line can be defined by the position coordinates of two points defining a virtual line.
    In these racing regattas, it is not only necessary to cross the starting line first respecting the top start but also with a speed of the boat closest to its maximum speed.
    In a race regatta, competitors have a pre-start that occurs 5 minutes before the start to maneuver to pass the starting line at best.
    It is known a device for assisting the crossing of the starting line comprising a means for creating a virtual starting line, a means for knowing the position of the boat instantly with respect to the virtual line, a means in view to know the instantaneous speed of the boat and means of calculations to indicate the distance with the virtual starting line and the time remaining before the start.
    From this knowledge of the remaining distance and time remaining, the boat must adjust its speed to cross the line, leaving the boat's commander a lot of choice and therefore uncertainties.
    However, if the skipper must maneuver his boat to adapt to this information, it will affect the start.

    The invention will be better understood from the following description given by way of non-limiting example with reference to the drawing which represents:<tb> Fig. 1 <SEP> represents a view of a body of water showing the starting line and the boat.<tb> Fig. 2 <SEP> represents a schematic view of a regatta assistance device.<tb> Figs. 3 and 3bis <SEP> represent a view of a body of water showing the remoteness line at its maximum distance from the starting line.<tb> Fig. 4 <SEP> represents a view of the body of water of FIG. 1 the countdown is started.<tb> Fig. <SEP> represents a view of the water plane of FIG. 1, the boat moving at the same speed as the line of removal.<tb> Fig. 6 <SEP> represents a view of a watch equipped with the assistance device.<tb> Fig. 7 <SEP> represents a view of a watch variant equipped with the assistance device.
    DETAILED DESCRIPTION
    Referring to the different figures, we see that it has been shown a body of water for a boat regatta.
    It has been shown in FIG. 1, the starting line 2 which can be determined from two geographical points A, B whose coordinates are, for example, data provided by geostationary satellites. There is also a boat 1 that must cross the starting line 2.
    The start of a regatta is an important moment. Indeed, it is necessary to cross the starting line after the start and at the most important speed because if the starting line is crossed before the start, the competitor has to turn around to then reverse the line in the right direction .
    Indeed, if to avoid crossing the line in advance, the competitor suddenly drops his speed, it will take a period before returning to speed and his departure will be bad.
    It is therefore appealing to a portable device 100 using a method of assistance from a boat participating in a regatta.
    The portable device 100, visible in FIG. 2, will include a calculator 10 for the overall management of the portable device. The portable apparatus 100 further comprises a satellite positioning means 11, a storage means 12 for storing the data and a means 13 for introducing into the computer and / or the memory information relating to the position from a starting line. This means 13 may be one or more buttons or tactile means.
    These means will be supplemented by means 14 to determine beforehand a maximum test speed associating for example a time base and the location device for determining a speed. However, it can be expected that the speed can be recovered from an external device.
    The computer 10 which may be a microprocessor or microcontroller, comprises means 10A for calculating a distance distance corresponding to the calculated maximum speed multiplied by a time T corresponding to the duration of a pre-race, means 15 to simulate the displacement of a so-called distance line at the so-called test speed Vm, means 16 for comparing the speed and the position of the boat relative to the displacement of the distance line L and the means 17 to provide information on speed deviation and / or distance between boat and outbound line.
    Incidentally, it comprises means for calculating an evolution of the speed of the boat so that its displacement coincides with an optimized displacement relative to a starting line to be crossed, and display means 19.
    In a first step visible in FIG. 1, the geographical points forming the starting line are recorded in said object. These geographical points can be manually entered or downloaded or saved by positioning themselves on a point of the starting line thanks to its GPS and by pressing a button of the portable object, the position will be memorized. The operation is repeated to get the second point to trace the start line.
    This method then comprises a second step or preparatory step of a duration T.
    In this second step visible in FIG. 3, simulating at least one race start to measure and record at least once a parameter that is the maximum speed Vm said test speed of the boat via the means 14 to determine a speed. This simulation takes the form of a pre-race test in real conditions. This speed information is used by the means 10A to calculate a maximum distance D that could be traveled during the pre-race duration T if the boat was moving at the said test speed and thus determine the position of a line L called maximum distance. This distance D is recorded by the computer 10 via the storage means 12. The latter can be a flash type memory.
    In a third step or starting step, the boat 1 is positioned between the line L of maximum distance and the starting line 2. The start of a countdown of duration T is triggered.
    During this countdown, the computer moves the line L away to the start line at the test speed Vm as visible in Figs. 4 and 5.
    Comparing then, via the computer, the position and / or actual displacement of the boat 1 parameters with the displacement of the line L distance. Indeed, the boat can be motionless or be in slight movement.
    This calculator 10 thus provides indications on the approximation of the distance L line with the boat 1 so that the boat 1 adapts its speed v and / or its route. This allows, when the boat 1 is caught by the remoteness line, said boat 1 to move at the same speed as that of said remoteness line.
    Therefore, as time goes by, the boat 1 will accelerate and the line L of distance will get closer to the boat. The difference between the speeds will be limited as well as the distance between the line of remoteness and the boat 1. It is thus possible to calculate parameters allowing a change in the speed and / or the road of the boat 1 so that its displacement coincides with the displacement of the distance line L, of course before the passage of the starting line 2.
    It will be understood that the various measures such as the distance of the boat 1 from the starting line 2 take into account the relative position of the boat. Indeed, the boat 1, in the direction of the wind, does not always sail in a straight line.
    This fact implies the existence of a real distance and a relative distance. The actual distance d1 is the shortest distance between the boat 1 and the starting line 2 while the so-called relative distance d2 is the distance between the boat 1 and the starting line 2 taking into account the direction of the boat. The actual distance d1 passes through a straight line perpendicular to the starting line 2. The relative distance d2 is calculated by determining the angle α between the line perpendicular to the starting line 2 which is the real distance d1 and the line formed by the direction of the boat as shown in fig. 3bis, d2 = d1 / cos α.
    Therefore, the computer 10 is capable, depending on the position of the boat 1 and its direction, to determine the actual distance d1 and the relative distance d2. It will be understood that for a regatta start, the real distance d1 is the important distance because the boat 1 is likely to tack so that the relative distance is unstable since it varies according to the angle α while the actual distance remains stable. The goal is to have the speed as well as the position of the boat 1 so that the end of its course during the pre-race coincides, both in distance from the starting line 2 and speed, with the displacement of the line of distance L which corresponds to a crossing of the optimized starting line 2.
    For this, the device provides the boat 1 information, for example, the speed difference, the distance between the distance line L and the position of the boat 1, as well as predictive instructions for changes in speed. .
    This information is provided by information means 20 and 19 display means. These information means 20 may be either in a digital form that is to say figures or in the form of visual indications such as indicator lights 21 or needles 22 moving on a marker.
    [0044] Preferably, the information is presented in the form of visual indications. Indeed, these visual indications are easier to apprehend insofar as the pilot of the boat 1 has other tasks in progress. For example, indicator lights may come on as colors can be used.
    In the case of color, an example may comprise a plurality of light indicators in the form of segments. These light indicators can be of different colors, the colors being associated with a particular information.
    In an example of the invention shown in FIG. 6, the portable object is provided with 11 light indicators. In detail, there will be 5 light indicators of a first color 21a, a light indicator of a second color 21b and 5 light indicators of a third color 21c.
    When the countdown is triggered, the 5 light indicators of a first color 21a are lit. The first color can be red. When the distance line L is going to get closer, indicator lights will go out so that the closer the distance line L is and the lower the number of illuminated indicators 21a will be lit. At this moment, the boat 1 accelerates.
    When the line L of distance is at the level of the boat 1 and the speed of this line of distance L is close to the speed of the boat 1, the indicator light of a second color 21b will light up . The second color can be green. This means that the boat 1 is in an optimal phase that is to say, it is at a good distance and with good speed to pass the starting line 2 optimally.
    If the indicator lights of a third color 21c start to light, it means that the boat is ahead of this distance line L and it must slow down. The third color can be orange.
    It can therefore be warned by a right-left distribution, that the boat 1 is ahead, in phase or late compared to a curve of evolution of its movement according to the lit color. The skipper is able to know if he is early (orange color), late (red color) or timing (green color).
    This also makes it possible to indicate whether this advance or delay is significant by means of the number of illuminated indicators 21.
    Of course, it is conceivable that the light indicators are in the form of three bars, each having a color. The bars for signaling the advance or the delay then consist of a plurality of zones so that the longer the advance or the delay, the greater the number of lit zones will be important.
    These means are housed in an envelope of a portable product such as a phone, a tablet or a watch case.
    The speed of movement of the boat 1 can be obtained by satellite positioning type GPS (Global Positioning System). Pressing a button on the watch or on the phone keypad also records the maximum speed. It is also possible to obtain this speed via an external sensor.
    The device can thus, as shown in FIG. 7, include a dial comprising a needle 22A which in the 12 o'clock position indicates that the difference between the instantaneous speed and the speed of the remote line is equal to zero. If the needle moves to the right on a scale 22B it could mean that the instantaneous speed is greater than the speed of the line of remoteness so that it is necessary to slow down, and if the needle moves to the left that the Instant speed is not enough. The amplitude of the angular displacement gives an idea of the importance of the difference; it is also possible to place the needle in front of an explicit pictogram representing for example a sign - or a + sign.
    A second needle 22C may as the previous indicate the distance between the line of removal from the boat on a scale 22D.
    Instead of needles, it can be segments in the form of camembert parts.
    As the simulation is done before the race, we can take into account the weather conditions by averaging different tests. This average could be affected by a correction depending on the wind speed measured at the time of the race. The maximum speed of the remoteness line can be the average of several simulations.
    It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention described above without departing from the scope of the invention defined by the appended claims.
    The storage means 12 may be a rewritable semiconductor mass memory using NOR or NAND technology.
    Moreover, the present invention will not be limited to a portable product such as a phone, a tablet or a watch case but may also be a bracelet or a laptop.
