The 2025 JRSC Turtle Island Race (for adult One-Design Classes) will be raced in the Ottawa River and the Maumee Bay. Racing will begin at the end of the JRSC T-Dock, proceed to an optional weather mark, down the Ottawa River, out into the Maumee Bay, around Turtle Island, and then back to the JRSC T-Dock. (Alternate racing only on the Ottawa River should weather conditions warrant.)
