vessels awaiting lockage as well as their schedule and direc-tion of transit. Each lock transmitter relays information related to its traf? c and status as well as its adjacent locks.All of this information is available for display on ves-sels using their existing VHF AIS equipment and an ECS that is AIS message 21 and Application Speci? c Message (ASM) capable. RosePoint – a marine navigation system and software provider – has been a leader in implementing the AIS ASM standards, which allows the AIS data mes-sages to be displayed in a user-con? gurable fashion. Rose-Point currently supports these e-Nav messages, but it must be enabled in the settings ? rst by enabling Experimental ASM in the Settings-Rose Point Labs menu.As more ECS providers enable their software to properly interpret and display the AIS information (which is be-ing received presently), the more readily all stakeholders can use the data. There are currently minimal standards for how the e-Nav information is displayed or portrayed on ECS; thus end users and manufacturers must work to-gether to ensure that the data are displayed in a useful, but non-intrusive manner. As the manufacturers adopt more of the e-Nav standards, the more con? gurable and custom-ized each ECS display can become.
