In the navigational rules What is the duty stand on a boat?

In navigational rules, the "stand-on" vessel is the boat that has the right of way in a crossing situation. This vessel is required to maintain its course and speed, while the "give-way" vessel must take action to avoid a collision. The stand-on vessel should be prepared to take evasive action if it becomes apparent that the give-way vessel is not taking the necessary steps to avoid an incident. It's important for the stand-on vessel to keep a lookout and assess the situation to ensure safe navigation.
