Evaluation of rowing speed andeffectiveness using the innovative “Laura” boatcompared to other rescue boats

Aim. The objective of this work was evaluation of rowing speed and effectiveness using the innovative “Laura” boat comparedto other rescue boats.
Basic procedures. The research was conducted in July 2017 on Rożnów Lake amongst 20 men within the age of 20-22 years, students of the University of Physical Education in Kraków. Their task was to cover a 100-m length in “Laura”, “Iwona” and “Mazurek” row boats. The evaluated items were speed of swimming by measuring the time to cover the route and the effectiveness by counting executed rowing cycles while rowing in a straight line – from halfway (50 m) to the buoy located in the middle of the return route (25 m before the finish).
Results. Based on the calculations, it was concluded that the fastest boat was “Laura” (average time: 105.22 sec) and the slowest was “Iwona” (average time: 143.74 sec). Also, basing on an analysis of rowing straight and round a buoy, it was proved that the subjects rowed the most effectively using the “Laura” boat, making less paddle movements than in the other vessels. Main findings. The results of the research authorize the statement that the innovative “Laura” boat, apart from its many pros connected with its design, allows efficient and fast rowing both in a straight line and when turning.
