The intense qualification phase for both « Light Transport » (LT) and « Mass Transport » (MT) categories of the HYDROCONTEST has drawn to a close last night at Pyramides de Vidy in Lausanne. During three days, the participants did everything in their power to get the best rankings possible with their light and heavyweight boats in order to be one of the 8 teams to compete in the quarterfinals. Right from the start, the competition has turned out to be full of stress, surprises and emotions for the competitors who had to dive into the deep end of energetic efficiency. Different levels of preparation of the prototypes, race strategy, and the heatwave – for both the students and their equipment… These are a few examples of the numerous factors that have tipped the scales in favour of results varying from success, sometimes unexpected, to complete failure.
