Cardinal buoys indicate an obstacle and the direction to use to safely pass it. They do indicate this by two cones, a colour coding and different flashing intervals at night. For those with nautical interest, more info can easily be found here.
You can use them to decorate your shoreline and make sure your ships steer clear of any danger zones and shallows. Content
