What action should you take to avoid a collision on a boat?

To avoid a collision on a boat, maintain a proper lookout by keeping watch for other vessels, obstacles, and navigational markers. Always follow the "rules of the road" for boating, which dictate right-of-way and safe navigation practices. If a potential collision is imminent, take early and decisive action to alter your course or speed, and communicate your intentions to other nearby vessels if necessary. Additionally, ensure your boat is equipped with navigational aids and safety gear.
