What is the primary function of GPS in small boats?

The primary function of GPS in small boats is navigation. GPS, or Global Positioning System, provides precise location information that enables boat operators to determine their exact position on the water. This functionality is crucial for maintaining a safe course, avoiding hazards, and reaching destinations effectively. Beyond simple positioning, navigation using GPS can include the use of waypoints, routes, and tracking movement, which are essential for effective travel over water.

While communication, speed measurement, and fishing assistance may also involve various technologies used on boats, they are not the core purpose of GPS. Communication typically involves devices like radios or satellite phones, speed measurement might use different tools or systems specifically designed for that purpose, and fishing assistance generally relies on sonar and fish finders. Thus, the navigation capabilities provided by GPS remain the most relevant and critical aspect of its function in small boating operations.
