Dangerous AIS Targets? New Challenges To Safe Navigation

A Busy Waterway, However The AIS Fish Beacons Give Me Great Fears


















Heading north around Cape Hatteras a few weeks back, we found ourselves facing a number of targets along our intended course - only some were more dangerous than others. That green target at top right of the image (36870200) was an American aircraft carrier performing incredibly tight turns and circles - but that wasn't the danger. Neither was the fast moving target to the left of our track (the track in black), which was the Captain Caden, a 21 meter fishing vessel out of Barnegat Bay.

FV Handful & Four Local AIS Beacons
The real danger was that tiny cluster of targets on our starboard side - the US flagged fishing vessel Handful, seen here with a cluster of AIS beacons around it (note : this image, and those that follow, is produced by replaying our voyage on our electronic nav system. The target shapes are different when in actual navigation mode). If we zoom in (at right), the picture becomes more clear - one primary AIS target, being the fishing vessel Handful itself, plus a cluster of four AIS fish net beacons floating around her. Fish net beacons, using AIS. Hmm. OK, read my lips. Say after me. This is not good....

The AIS system was devised and built as a safety system for vessels under management. It was not built as an identification system for unmanned, unpowered fish net and long line floats that do not ask questions and cannot correct their course. If the technology is used for net tracking, the targets should display with a clearly different icon or graphic on screen. But they do not. They look just like ships on screen.

The IMO (International Maritime Organisation) has published guidelines for the display of navigation related symbols on screen (read them here) and no fishing target beacons are included. The United Nations Food & Agriculture Organisation has published a draft paper (read it here) on marking of fishing gear, which acknowledges the illegal nature of AIS fishing beacons, but doesn't come down against them.

Thanks to Ben Ellison, author of the excellent PANBO marine electronics blog, I obtained the following information from a US Coast Guard website :

"18. Can I use AIS to mark nets, pots, traps, moorings, or as a race mark, etc.? There are no outright prohibitions to use AIS (i.e. AIS AtoN) as a marker (see Types of AIS and IALA Recommendation 1016 – Mobile Marine Aids to Navigation). However, it is not permissible to do so with equipment intended for use on vessels, (i.e. AIS Class A or B devices), for lifesaving (i.e. AIS SART, MOB AIS, EPIRB AIS), or with devices that are not FCC certified and licensed. See 47 CFR §§ 2.803, 2.805, 2.301, and 80.13 regarding licensing, station identity, and the prohibition to sell, market, or use radio devices that are not FCC authorized (search, Equipment Class: AIS)." It appears then that so long as these devices are FCC approved, they can be used at sea. But are they FCC approved?

So, what has gone wrong? Firstly, Chinese manufacturers have seized on an opportunity to use AIS electronic packages as fish net beacons, though without any approvals from relevant international AIS scheme managers. Secondly, US fisherman keen to track their nets (at  very low cost) have seized on these tools and deployed them, even though they are illegal under US law (my opinion). In fact you can't buy these readily in the USA - you have to order them online through Ali-Baba or one of the foreign web supply chains.


















Above is the Ova fishing buoy beacon, sold out of China on the internet for not much over US$100.00, waterproof to 10 meters, and it comes pre-programmed with it's own MMSI number. Wait a minute - how did that happen? An MMSI number is supposed to be a Maritime Mobile Service Identifier - a number that identifies a vessel and an owner and tracks back to the national registration of the identified vessel.

Who ever heard of MMSI numbers being issued by the factory that built the product.... geez. They are supposed to be issued by the country of registration!

Then there are other brands and models - in fact there are so many models that there is an entire market place on the web where you can buy these (illegal) devices. Check out the page at this address. Many are shipped with software on disk plus a cable that allows the user to program the MMSI number - this is completely illegal under US FCC regulations.

Many fisherman, reading this story, will be wondering what the heck I'm complaining about - OK so it's illegal, but where is the harm? In fact it can be said that the fisherman are doing us a favor by identifying nets and floats that otherwise would be invisible to us at night. However until these beacons can be identified easily on screen as floating beacons (and not ships), then I believe that some dangerous situations are being created. Read on for the story on that ....

Ocean Cruising Club - Potomac River History Cruise

OCC Dinghy Drift At Leonardtown (Image Courtesy Tong Gibb)
Last Saturday the Ocean Cruising Club started a six day mini-cruise of the lower Potomac River, from here in Reedville, Virginia. We joined the group of 25 boats for those few days, visiting St Mary's (the original capital of Maryland) and also Leonardtown. Both cities have a long history dating to before the revolutionary war - in fact Leonardtown was burned by British Marines during that war.

On Wednesday night the boat crews met upstream for a sunset dinghy drift - combining the boats together in a massive raft and then drifting downstream as the cocktails and nibbles were passed from boat to boat. Lots of fun that continued for several hours. Thursday was Flag Day here in the USA, so we dressed ship to join in the celebrations. This morning we cruised back down the Potomac River to Reedville once again, where Crystal Blues will rest until the end of the month.

Return To Reedville

Crystal Blues Shares The Dock, With The Beautiful Grand Banks Trawler Slow Dancing, Plus Dingies From The Visiting OCC Fleet

















On Virginia's "northern neck", Reedville is a small village with a proud commercial fishing history. Right now it has aged gracefully to become a popular retirement and vacation area, set among rural farmlands, surrounded by a myriad creeks and bays.

Reedville Peninsular
Its a beautiful environment, still with a large population of working watermen, engaged in oystering, crabbing and net fishing. A fleet of large trawlers still work the Menhaden schools at the bottom of Chesapeake Bay and in the nearby Atlantic ocean. The Menhaden fish has been called "the most important fish in the sea". By tonnage, Reedville is still the second largest fishing port in the USA.

The Menhaden fishery once gave Reedville a fabulous wealth - it had the highest per capita income in the United States. Millionaires row in Main Street Reedville is evidence of this - scores of magnificent homes line the single street that forms the spine of this tiny peninsular.

Our friends Walter Keith and Mary Frazer have welcomed us back to their home and dock. There is a busy social calendar this time of the year, and in between music and social events we're trying to work on maintenance and repairs, but that is proving difficult.

On June 9th the Ocean Cruising Club started a Potomac River History Cruise from here, so we suddenly found the anchorage filled with 25 visiting OCC boats. Then cruising friends Bill & Jean Crew arrived on Pelican Express, with four legged crew mate Bella. Local friends are also calling to welcome us, several arriving by boat.

 Yesterday was a big day for the OCC rally group - they came for cocktails here at Walter & Mary's home, then we all crossed the street for the first musical concert of the year at the Reedville Fisherman's Museum. Bluegrass and country rock kept our feet tapping until predicted thunderstorms shut down the evening.

Between the rain storms the social schedule has been frantic and the maintenance schedule continues to take a beating. Tomorrow we're off to cruise the lower Potomac River for three days with the OCC.

Back In The USA , Its Springtime Cruising


Arrival At Sunset, Chesapeake Bay




















778 nautical miles later, we arrive in Norfolk, Virginia, after a very quick (3.5 days) transit from Great Sail Cay in the Bahamas. For the sailors reading this, that is an average of 9.26 knots. Of course we had 3 to 4 knots of lift from the Gulf Stream current for some of the passage, but we were pleased with our sailing speeds never the less. Cleaning the hull underwater, before we departed, also helped quite a lot.  The passage was completed with about 80% of the distance under sail, so not too much motoring.

Approaching The Sea Buoy Off The Chesapeake Bay Entrance
The warm weather had followed us north, so we sailed into harbor in shorts and not much else. After anchoring overnight we moved into a commercial marina berth the next morning, to allow for the necessary inspection by Customs & Border Protection

The clearance process here was simple and friendly, unlike the fairly shabby treatment we had received in Charleston the previous year. Next day we visited the Customs offices to obtain our 12 month Cruising Permit, and with that last piece of paper in place we could relax - we'd officially arrived.

In our approach, our first time here, we passed the enormous US Navy ship yard complex that stretches out along both sides of the river - a spectacular statement about US military expenditure - there were more ships here in just one river than in the entire Royal Australian Navy.




















Rockets R Us























OK, so the 10.0 knot speed at the top of the screen possibly caught the eye of the boating folk, but that's what happens in the Gulf Stream heading north. However anyone familiar with my dim dark past will smile at the small print on the navigation screen, just ahead of us in this image .... rocket impact area? Yes, we are south east of Cape Canaveral, where Ley and I watched the Space-X launch late last year, and where I watched the last moon shot (Apollo 17) take off back in 1972. Memories can surface on the midnight watch.
