## Quick answer

Strictly follow the lateral buoys through the narrow Coatsworth Cut channel and monitor late-season water depths, which drop from 8 feet to 6 feet, avoiding all unmarked shallow hazards outside the lane.

## Detailed answer

Navigating Coatsworth Cut from the Ashbridges Bay Boat Launch requires strict adherence to the marked channel due to significant seasonal marine logistics constraints. The cut is a notoriously narrow passage clearly defined by lateral buoys; boaters must stay precisely within these markers. Straying even 10 feet outside the designated lane poses a severe risk of grounding or damaging your vessel on underwater shallow hazards, such as submerged rocks and shifting sandbars, which are unmarked and extremely unpredictable. Water depth constraints are a critical factor for a safe transit. Early in the boating season, the channel typically maintains a navigable depth of approximately 8 feet at average water levels. However, as the season progresses into late summer and early fall, water levels recede significantly, causing the depth to drop to a mere 6 feet or less. This 2-foot reduction means boaters with deeper draft vessels must calculate their clearance carefully, accounting for the vessel's draft, the weight of cargo and fuel, and the engine's lower unit. Always plan your transit during calm conditions to minimize squat, and proceed at a slow, no-wake speed to maintain full steering control while closely monitoring your depth sounder within the 8-foot to 6-foot transition zone.
