Do you personally pronounce this word booo-eee or boy? I'm a booo-eee speaker.
Sometimes you can use the tilt of markers to tell which way the current is going and how strong. Once we saw this huge marker tilted over at a 45 degree angle and were worried until we saw a huge fat sea lion on it.
Here is a smaller sea lion making a smaller angle on a buoy as we came by Port Townsend on our way to the Wauquiez Rendezvous this year.
