When a powerboat is approaching the starboard side of a sailboat in darkness or reduced visibility, it must maintain a safe distance and be prepared to take evasive action if necessary. According to navigation rules, the powerboat is considered the give-way vessel, meaning it should avoid interfering with the sailboat's course. The powerboat should also ensure that its navigation lights are clearly visible to indicate its presence to the sailboat.
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.
