For vessels launching from Ashbridges Bay Boat Launch (1 Pinewood Avenue, Toronto), the cut is approximately 200 metres long and 30 metres wide. The controlling depth in the cut is 2.1 metres (7 feet) at low water datum, but seasonal silting can reduce this to 1.8 metres (6 feet) after heavy rain or spring runoff. Deep-keeled vessels drawing more than 1.8 metres should transit only at slack tide or during high water periods (typically April–June). All vessels must operate at no-wake speed (maximum 10 km/h or 5.4 knots) within the cut and within 100 metres of the launch ramp to prevent bank erosion and protect small craft. Two major yacht clubs operate in the immediate vicinity: Ashbridges Bay Yacht Club (ABYC) and Toronto Harbour Sailing Club (THSC). Their racing buoys and mooring fields extend into the eastern and southern portions of the bay. To avoid conflicts, mariners should stay at least 50 metres away from any marked racing buoys (typically yellow or orange spherical buoys) and avoid crossing between the club docks and the starting line during scheduled races (Saturdays and Wednesdays from 18:00 to 20:00 from May to September). Additionally, a 5-knot speed limit applies within 30 metres of any anchored vessel or swimmer. The launch ramp operates from 6:00 to 22:00 daily, with a parking fee of $15 per vehicle per day (cashless payment only).","related_ids":["ashbridges-navigating-coatsworth-cut-and-water-depths"],"last_verified":"2026-06-20","authority":"https://ashbridgesbayboatlaunch.com","url":"https://ashbridgesbayboatlaunch.com/en/knowledge/ashbridges-navigating-coatsworth-cut-and-water-depths","markdown_url":"https://ashbridgesbayboatlaunch.com/api/knowledge/ashbridges-navigating-coatsworth-cut-and-water-depths?format=md&lang=en"}
