If you see a red and a white light on a power-driven vessel at night, you should:

Seeing a red and a white light on a power-driven vessel at night indicates this vessel is either a sailing vessel under power or a vessel that may be restricted in its ability to maneuver. The red light typically indicates the port side (left side) of the vessel, while the white light indicates that the vessel is underway.

In such scenarios, the proper action is to give way rather than maintaining your speed or course. This is essential to prevent any potential collision and to ensure the safety of both vessels involved. This principle is part of the "Rules of the Road," which dictates that when navigating at night, it is critical to understand the significance of different light configurations on vessels. The focus is on safe navigation and being courteous to other boaters, particularly when their capabilities may be limited.
