The 2021 Hydroplane Racing League season kicks off in Cambridge, Maryland, USA.
The calendar, which runs from May to September, is made up of eight events in Canada and the United States. The most anticipated event on the schedule is without a doubt the Salaberry-de-Valleyfield edition which will take place on July 16, 17 and 18.
The HRL organization wishes to stress that the holding of the events will be conditional on the health measures dictated by the public health and government authorities of the region where the event will be held. Other factors may be taken into account.
