NTSB: F/V Tremont Hit MSC Boxship as it was Fixing Gyrocompass While Underway

The 115-foot trawler had a crew of 12 plus the captain and mate’s 2-year-old child aboard as a passenger when it left New Bedford, Massachusetts on October 7, 2022, for squid fishing off the U.S. East Coast. The crew told the NTSB about four or five days into the 20-day trip “the vessel’s gyrocompass became ‘kind of sporadic,’” but since the error was last than 10 degrees the captain and mate, “determined it ‘was something we could live with,’” and so they continued to operate along the East Coast. They also knew that the vessel’s AIS was not fully functioning and while it was transmitting it was not displaying on the trawler. more, >>click to read<< 07:41

North Korean fishing trawler presumed scrapped returns from the dead

A large North Korean fishing vessel supposedly scrapped years ago reappeared last month, state media showed, renewing uncertainty over just how well ship trackers can monitor the country’s commercial fleet. The ship in question is the Sam Chon Li 1, a 3,800-ton trawler that last broadcast over its automatic identification system (AIS) in late 2018 with an unknown destination, according to maritime intelligence platform MarineTraffic. Records show the ship is either “decommissioned or lost,” suggesting it had been scrapped. But KCTV footage from late last month appears to show a fully intact Sam Chon Li 1 docked at Sinpho,,, >click to read<  21:48

Marine Navigation Safety Regulations 2020: Canada Announces New Marine Regulations to Improve Safety, Security and Protection

Canada has published new Marine Navigation Safety Regulations, which now apply to commercial vessels of all sizes, including fishing vessels, workboats, water taxis and ferries. The new regulations, which reflect extensive consultation with Canadians and the marine industry, represent a consolidation of nine existing sets of marine safety regulations into a single one,, The Marine Navigation Safety Regulations 2020 require vessel owners to have equipment to help reduce the risk of collisions that could cause pollution, like oil spills, and threaten endangered marine life, such as whales. They are also required to have lifesaving equipment that will send emergency signals and provide the vessel’s location. >click to read< 08:38

Ray Hilborn: New study provides no new information on global fishing footprint

University of Washington fisheries researcher Ray Hilborn said that a new study using satellite data from industrial fishing vessels to map global fishing effort fails to provide any new insight, despite media reports indicating otherwise. The study, published in Science in February, used messages transmitted between 2012 and 2016 from the automatic identification systems (AIS) of more than 70,000 industrial fishing vessels to create a global footprint, concluding that “industrial fishing occurs in over 55 percent of ocean area,” according to the abstract. But Hilborn said the vessels monitored for the study were in large part tuna boats over 100 feet, which have been monitored for decades. >click to read< 11:17

AIS Regulations: New Responsibilities and Opportunities

uscg logoFrom increasing situational awareness and enhancing the safety and security of maritime transportation, to its use in accident investigation, search and rescue, Aids to Navigation and asset monitoring, the role of AIS (Automatic Identification System) as a flexible and developing technology continues to grow in significance. The month of March 2016 – has come and gone – and represents an important milestone which will increase the prevalence and general awareness of AIS. As new United States Coast Guard regulations are introduced, more commercial vessels working along U.S. coasts will need to be equipped with AIS, affecting all mariners in U.S. waters.
