When arriving to KNGP from the south, which point marks the crossing of the beach line?

The point that marks the crossing of the beach line when arriving at KNGP from the south is indeed Port Royal. This is significant because the beach line often serves as a geographical reference for navigation and approach to coastal areas.

Port Royal is recognized as a notable landmark in this context, as it is positioned along the shoreline and plays a critical role in delineating the boundary between the land and the water. Being familiar with such landmarks is essential for pilots or navigators in ensuring safe and efficient travel to and from coastal destinations. Understanding the beach line is crucial for various activities, including determining approach angles and ensuring proper clearance over water.

The other locations, while they may have their own significance or be relevant in other contexts, do not serve as the primary marker for the beach line in this scenario.
