Sažetak
As a part of the hydrofoil optimisation project for windsurfing, a system for measuring vessel motions,
weather elements and water conditions was developed. By measuring the speed, acceleration, angular
velocity, inclination and direction of the vessel movement and weather elements in real time, the
hydrodynamic optimisation process of hydrofoils was accelerated. Measurements were performed with
a measuring device attached to the observed vessel, while measurements of weather elements and sea
conditions were performed with another device on the accompanying vessel. Wind speed, direction
and temperature, environmental temperature, atmospheric pressure, surface water current and wave
properties were measured. By combining data from both devices, a database was created on the state
of the environment and the vessel motions. Analysis of the database provided the necessary data for
the hydrodynamic optimisation of the hydrofoil. The polar diagram of the vessel speed in relation to
the speed and direction of the wind, together with the data on the inclinations of the hydrofoil and the
angle between the direction of movement and the pointing direction at the moments of reaching the
maximum speed, accelerate the hydrofoil hydrodynamic optimisation process.
