Portable object for regattas

A race start assistance method for a boat participating in a regatta including a pre-race having a duration before the crossing of the start line, the method comprising:

• creating and storing the start line in virtual form, and determining the instantaneous speed of the boat and the position thereof with respect to the start line, in order to provide at least one indication on how to proceed in the pre-race;
• simulating, prior to the race, at least one race start is-simulated by performing a pre-race test, to measure and store, at least once, a parameter that is the maximum speed or test speed of the boat, to deduce therefrom a maximum distance that could be travelled during the pre-race duration if the boat moved at said test speed and thereby to determine the position of a line called the maximum distance line;
• and
• starting, after positioning the boat between the maximum distance line and the start line, a countdown period having a duration during which, on the one hand, the distance line moves towards the start line at the test speed while the boat also moves towards the race line at a lower speed than the maximum test speed and during which, on the other hand, the actual motion parameters of the boat are compared to the movement of the distance line to provide indications on the closeness of the distance line to the boat to enable the boat to adjust the speed and/or route thereof so that when the distance line catches up with the boat, said boat is moving at the same speed as said distance line.
