Re: AIS Everywhere

The VTS buoys here in Puget Sound are mostly in 600 to 700 feet of water - so again - they are not about running aground - but to keep ships from running into each other - ATON's have many uses -

Maybe I am a Luddite - but in talking to captains of large vessels they still reference the physical buoys - they still look out the windows - and seems to me having a physical buoy helps to give that visual edge

Re: AIS Everywhere

My guess is the first physical ones to be replaced are going to be the entrance markers in very deep water. We have some on the gulf coast that are dropped in very deep water and mark the entrance to safety ways or regulated zones. Not that people don't need to know where they are, but no one is going to run aground if it isn't there.

I don't see ais replacing channel marks very soon, since so few recreational vessels have ais so far.

At the recent USCG GMDSS Task Force meeting one of the USCG reps said there are 80 synthetic (AIS on top of physical ATONs) ATONs in place. He said that sea buoys will be the first to go virtual. I don't know if that was policy or opinion.

Re: AIS Everywhere

They are adding AIS to some of the sea buoys - that gets the collision avoidance and CPA of the navigation systems to help ships know when they will hit a buoy -

What I have seen so far is the adding of AIS to ATON's but not replacing ATON's with AIS. Remember that not all boats have AIS systems on board.

I got a ride on the Coast Guard Cutter Healy - an Icebreaker - I ask the Captain about using physical ATON's vs/ depending on their fancy dual navigation systems - his reply was that the watch-standers ALWAYS used the physical ATON's - he said that he had all the electronic nav systems go out once (not sure which ship it happened on) - and he was not taking any chance - the paper charts they had out had special symbols (triangles, squares etc.) so a lookout could tell what type of ATON was there from 4 feet away from the chart (there are a couple of pictures of the chart on my article about the Healy trip on my site, sorry the pictures are not very large, but you can see the general idea)

At the ATON listening session I went to the Coast Guard repeated several times there were no plans to replace large numbers of physical ATON's with electronic versions - however - that person was getting ready to retire and spent his entire life working with ATON's and started on ships when there was not much in the way of electronics for navigation - so hard to say what will happen when the "video game generation" are in charge.

Re: AIS Everywhere

Sea buoys--very expensive to place and maintain--will be the first to be replaced with virtual ATON.

Re: AIS Everywhere

Many interesting points in your article. One is that there are "92,000 aids to navigation" in the USA alone!
If you look on a more international basis and see the cost saving WORLDWIDE if only 20% of physical AtNs are removed.

Some structures at sea or on the coast are so huge they must cost millions to build and more to maintain.

I am not suggesting we get rid of them all, but now for example, Singapore Straits only has a physical marker every 5nms.

Other new thing about AIS is in New Zealand they have made a virtual channel marker bouy with an AIS unit placed on land beaming the signal so it appears the marker is on a submerged rock.

In the future a lot of difficult markers and channel marks may well be vortual AIS marks.
That is also being done in the U.S also - but in some cases they put an AIS transmitter on the physical ATON (giving the true position of the ATON), the AIS can transmit a signal that matches to a physical ATON or as in the above example they have an AIS signal where there is no physical ATON (three flavors to choose from)

Since AIS can be turned on an off it is also being used for temporary safety zones such as yacht race courses

A while back I wrote an article for my web site on changes to Aids To Navigation: 21st Century ATON?s & Waterway Safety | Boating Safety Tips, Tricks & Thoughts from Captnmike

to be hit by or to hit a mexican panga means your life as you know it ENDS. they OWN you. keep your eyes open at all times and do not be fooled by fancy tools that aree not adequate to find everything on the surface of the ocean.
whats a mexican panga?

Re: AIS Everywhere

The R10 SRS is a great idea and has only one purpose. The ability to find a man overboard by watching your AIS screen is a must at night and in big seas. If you are going offshore and have AIS then all crew should have the R10 on their PFD. Besides the R10 SRS, your PFD should have a tether cutter, whistle and strobe. In the old days we had the MOB pole in bright orange and all offshore boats with crew still should have one on board but for anyone who has ever used one in 3 meter seas or better knows they are hard to see. The R10 SRS is just a far better idea than the MOB pole, thank god for modern technology.

Let us hope that no one ever has to use one.
