published. However, it has been suggested that the data is the first step to improvementswithin the sport. There is little evidence of quantitative data for water skiing available inthe research literature, and this has most likely limited development within the waterskiing industry.This study was developed to overcome the challenges of applying an IMU/GPSinstrumentation system in the natural environment of water skiing, and to providequantitative data to analyse water skiing’s complex kinematics. It expanded on the workof Runciman (2011) to include a more structured experimental procedure that providedqualitative data for the performance of six advanced slalom skiers on four different skidesigns. The goal was to be able to identify different performance achievements on thedifferent ski designs as well as identify different performance achievements between theskiers. Advancements in sports technology will allow for the implementation of animproved instrumentation system that will be able to produce quantitative data that willfill the void found in literature. This type of data set will act as a tool for improvedanalysis of skier performance and being able to assess skier performance in more detailthan previously possible will act as the primary step towards advancements in productdesign and coaching techniques.22
