“…Hence, approaching performance analysis through the riders' perspective is complementary with statistical approaches of performance analysis. 2,14 However, while technological developments now provide a wide range of tools to measure performance "from the outside" (e.g., wearable GPS, compact waterproof and shockproof inertial measurement unit), little has been done to measure performance "from the inside" in an appropriate way that takes into account the constraints of the actual practice sessions.…”

“…5 Research on sailing in sports science has focused on three main topics: (a) physical characteristics of the sailors, studying the biomechanical, physiological, and anthropometric determinants of performance, [6][7][8][9] (b) psychological aspects of performance, studying the process of decision-making with regard to strategic choices, 10,11 and (c) statistical analysis of GPS data to compare the speed and distance covered by the sailors. 2,[12][13][14] For example, in Formula Kite, the speed, distance traveled, number of maneuvers, and time spent on the courses of upwind, downwind, and beam reach of Olympic sailors were analyzed. 2 To do so, researchers used data collected through the SAP-Sailing® application during Formula Kite-class World Cups.…”

Formula Kite is a high-speed sailing sport using hydrofoils, recently included in the Olympic sports list. In Formula Kite, the riders’ technical abilities to reach and maintain high speed are key to achieving performance. The aim of the present study was to analyze Formula Kite riders’ performance during speed tests in practice sessions by combining qualitative descriptions of their lived perceptual experiences “from the inside” with measured correlates of performance. The courses of experience of four expert Formula Kite riders’ speed tests were analyzed, compared, and discussed in relation to their measured Velocity Made Good. Results of the qualitative analyses provide original insight into the fine technical adaptations of the riders in their pursuit of performance. Furthermore, the comparison between the evaluated performance using speed measurements and the perceived performance assessed by the qualitative analysis shows interindividual differences as well as inconsistencies between the two modes of analysis. Based on these results, the present study opens practical perspectives for improving training practices, consisting in “calibrating” the sailors’ perceived performance with measured performance.

The open-water training conditions in sailing sports limit the coach’s ability to provide instructions. Auditory feedback provided using a smartphone application in real-time seems to be a promising tool in the training process. The aim of the study was to assess the usefulness of a smartphone application created to support tactical decisions via an auditory display. Thirteen successful windsurfers competing in RS:X class took part in the study. The results, collected with the use of a questionnaire, related to the technical and aesthetic aspects of the functions as well as decision-making assistance of the application during upwind sailing races. Most of the competitors positively evaluated application function (54–85%). Real-time information about the deviation from the set course and information about potential tack change due to a changed wind direction were statistically significantly more helpful for less experienced windsurfers (rho = −0.68 and rho = −0.78, respectively) and those with lower sports level (rho = −0.63 and rho = −0.65, respectively). It can be concluded that the use of sound feedback in the conditions of training on-water in sailing has potential, primarily for younger and less experienced competitors. Quantitative evaluations of the sailing performance should be considered in further research on the functionality of the application.

The aim of this study was to analyse the variables that determine the performance of the Optimist class during a regatta in different wind conditions. A total of 203 elite sailors of the Optimist class (121 boys and 82 girls) participated in the study. According to their ranking in the regatta, the sample was divided into four performance groups. In a regatta with 11 races, the velocity made good (VMG), the distance and the manoeuvres were evaluated by means of GNSS equipment in three different courses. The boys performed a greater number of upwind and running manoeuvres than the girls. The very-low-level sailors obtained a lower VMG in all the courses analysed compared with the rest of the groups of sailors of higher levels. Upwind manoeuvres, broad reach and running VMG were significant variables for establishing differences in performance level when the wind speed was in a range of 5 to ≤8 knots. When the wind speed was in the >8 to ≤12 knot range, upwind distance was the key variable in determining performance differences. VMG, upwind and broad reach distance and broad reach manoeuvres were the most important variables when the wind speed was in the >12 to 15 knots range. The boys performed more manoeuvres than the girls in the upwind and running courses.
