What action is required of powerboat when approaching a sailboat head on in darkness or reduced visibility?

When a powerboat approaches a sailboat head-on in darkness or reduced visibility, it is required to take action to avoid a collision. The powerboat should alter its course to starboard (right) to pass the sailboat on its port side (left). Additionally, the powerboat must ensure it is displaying the appropriate navigation lights to signal its presence and intentions. Maintaining a proper lookout and safe speed is also essential in these conditions.
