The production quality is very impressive It made my day better.

I have been studying for my OUPV six pack, and this was a fantastic explanation. I really appreciate the clear diagrams and scenarios. Thank you!

One way I remember green markers are odd numbered is a slogan I came up with "green is odd, and if you're odd your square".  My other saying is for the ICW. That saying is "green tea - green sea" meaning in most cases is if I am south bound on the ICW on the east coast of the USA I should keep my green markers to my port.

These rules only apply in the US. In Australia the red markers are to port and green to starboard when returning to harbour. This might be good to note in the videos.

OMG, you did a fantastic job on explaining this Nav aids, after i watched many youtube videos, yours is the most cleared one. keep it short keep it clear!

This was a great refresher course, since I already have my FL Safe Boater card after taking the course at my local USCG Auxiliary back in 2012.  Thank you !!

Thanks Scott, this was super helpful! - extra helpful for me personally because I work on the architecture tours in Chicago and in the harbor so I knew where I was haha

Great boating the USA instructional video.

In Canada we use some different terms but the international system is similar otherwise. I live on the Canada-USA border and I have sailed all the Great Lakes and the connecting rivers (except Lake Michigan) all the way to the Atlantic many times. I have never seen a preferred channel marker showing two colours on four parts. They are always two colours on three approximately equal-size parts. I believe your example of a port hand preferred channel buoy should appear as green, red, green. In the video the top and bottom parts of the preferred channel marker should be green and cover a total of approximately 2/3 of the buoy with the middle 1/3 red. A simpler description would be a green buoy with a red band. I like to associate the main colour with the main channel. Pass the buoy as though it displays only its main colour to continue in the main channel. Pass it as though it displays only its secondary colour to enter the secondary channel. Ultimately a preferred channel buoy is two buoys in one. It marks the boundaries of both the main and secondary channels where the port side of one channel meets the starboard side of the other.

Great job love it... Thank you so much

This is one of the clearest and informative explanations I've seen yet. Thank you very much !!

Great video. Thank you

Well done! I now have clarity regarding returning to shore vs. ICW markers. Thank you!

Perfect example of explain it to me like im 5 years old lol

Thank you for your very clear explanations.

comprehensive explananation.

My friend, It's called Aids to Navigation, not Navigation Aids.

The Nav aids are the tools in the vessel, such as ECDIS, Radar, GPS, navigation charts, etc.

But the Aids to Navigation are buoys, beacons, lighthouses, etc.

Great video!! Thank you for making it! Very clear!

well done Captain Scott!  Excellent teaching/demo methodology to assist learning :)

This is excellent Captain. New subscriber.
