To avoid running aground in unfamiliar waterways, what is the best practice?

Obtaining a nautical chart or seeking local advice is the best practice for avoiding running aground in unfamiliar waterways because it provides critical information about water depths, underwater hazards, and navigation aids specific to the area you are navigating. Nautical charts are designed for boaters and include detailed representations of the waterways, including shallow areas, rocks, and obstructions. Additionally, local advice can offer insights not always captured in charts, such as current conditions, seasonal changes in water levels, and any recent hazards that may not yet be charted.

Using a nautical chart allows boaters to plan their routes more effectively and make informed decisions about where it is safe to travel. This knowledge significantly reduces the risk of hitting bottom or encountering obstacles that could cause damage to the vessel or jeopardize the safety of those onboard.
