Two boats are operating near each other. which is the boat that maintain its course?

In maritime navigation, the boat that maintains its course is typically referred to as the "stand-on vessel." This vessel is required to continue on its current path while the other boat, known as the "give-way vessel," must take action to avoid a collision. The stand-on vessel has the right of way and should not alter its course unless it becomes apparent that a collision is imminent.
