You enter a harbor. You see a lateral spar buoy with red and white vertical stripes. What should you do?

The lateral spar buoy with red and white vertical stripes indicates that you are approaching a channel or area where you should keep the buoy on your port (left) side while navigating. This marking typically signifies a safe route for vessels. Be sure to maintain a safe distance from the buoy and follow any additional navigational aids or local regulations as you proceed into the harbor. Always exercise caution and keep a lookout for other vessels or hazards.
